Transparent Ready is the Schneider Electric communication solution that gives you access to important data available from your Medium Voltage and Low Voltage power equipment.You can access them wherever you are, from any PC connected to your Intranet via a simple Web browser.There are many parameters to take into account in order to retain control over an installation: energy, current, voltages, cos

ϕ

, harmonic distortion level, load trip analysis, etc.These parameters are essential in order to understand the electrical phenomena of an installation. The number of parameters to consider depends on the site’s activity¸ on the installation, on performance levels, on the expected accuracy, etc.It is therefore important to correctly target your requirement before any approach to select equipment so that the selected metering devices are suited to your requirements.Furthermore, you must not forget that metering is only a tool that helps solve electrical problems more effectively; it cannot solve everything by itself. The interpretation of measurements is a decisive factor in terms of the results obtained.

Keep control over your power consumption

Transparent Ready provides comprehensive, real-time, permanent andremote power consumption data. Consumption by building, sector, unit, workshop, site, excessive or abnormal consumption, variations, you have all the data you need to make direct savings on your electricity bill.Electricity is one of the energy sources consumed by the end user (building, factory, workshop, etc.). The costs of this energy are constantly increasing. End users can therefore benefit from monitoring their electrical network to avoid any wastage and to provide power where it is really needed.

Improving power supply availability

With Transparent Ready, you anticipate production stoppages.Transformer overloads, phase unbalances, motors exceeding their running time among other faults can cause production facility downtime. Finding out about possible malfunctions allows you to anticipate faults in your power supply and therefore improve its availability.Continuity of service is a key issue. By monitoring the installation, managers opt for preventive maintenance, which is a much more flexible method in terms of actions and, in the end, less costly for the company.

Better managing your electrical installation

Your electrical installation is constantly monitored by Transparent Ready.Knowing the status of your electrical equipment means that you get the full benefit of its performance capability. This allows you to optimise installed base management and investment spending.

How to make your electrical network Transparent Ready ?

Methodology is important to the approach as it determines the performance and profitability of the monitoring solution. It basically depends on the consumer's priorities which generate requirements:

b

for keeping control over your power consumption

b

for improving power supply availability

b

for better managing electrical installation.

Preliminary step : check the current situation and build a financial scenario

The need for a metering installation is justified by the gains it will bring. A solution that covers the entire installation represents a major boost to company competitiveness, but also requires the appropriate staff to use the capacity properly.

DB

1077

82

Step : set up priorities

Every facility has specific needs and has a specific electrical distribution architecture. According to the application, we can determine which priority should be allocated from among an end user's three most important concerns covered by the Transparent Ready solution: monitoring consumption, power availability and installation optimisation.

Example: if the application consumes high levels of electricity and is not sensitive to electricity quality, the suited metering system should guide us to the right metering products.In the same way, a highly sensitive application relative to electrical power quality will require a different type of metering product.

Step : define key electrical values

b

once priorities have been decided, we can define the key electrical values to be integrated into the metering system

b

the parameters to be taken into account allow us to detect a disturbance or a phenomenon as soon as it appears, i.e. before it has any detrimental impact on the electrical installation and its current consuming devices

b

the method involves installing a suitable device on every feeder involved, so as to be as close as possible to requirements and another one at site installation head to provide an overall view.However, we also have to identify feeders that are vital for the company’s activity and feeders on costly processes in order to integrate this information into the solution.

Step : select the components

The Transparent Ready Equipment and Products chapters in this document let you select the right products.For existing installations: some of your power equipment already integrates metering products.

Example: protection relays often have metering capability.

You only need to let them communicate via a Modbus serial link to the Intranet.

Measures that put you in control

0

DB

Once the metering system is installed on the electrical network, it becomes possible to interpret the measurements based on two analysis levels:

b

electrician's level: the special user of Transparent Ready solutions

b

electrotechnical expert's level: present in all companies highly dependent on electrical power (end user, contractor, panel builder, design offices or Schneider Electric).What follows in the document presents a summary of interpretations of the measurements provided by the Transparent Ready solution and intended for electricians.

These measurements are linked to the three major benefits you derive from Transparent Ready solutions:

b

keeping control of your power consumption

b improving power supply availabilityb better managing your electrical installation.

14



Energy-power

DB

1077

84

There are three parts to your electricity bill:b subscribed apparent power, the fixed part of your billb consumed real energyb consumed reactive energy.

Example: in France, electricity bills can roughly be split into:b 40 % network connection cost as set by government regulationsb 20 % national and local taxesb 40 % energy consumption.

Power and energy levels are taken into account for monitoring electrical consumption as well as for predicting when existing installation capacity will be exceeded.These electrical values vary according to:b the type of processb the season, if outdoor temperatures vary considerablyb date and timeb changes or extensions of the siteb etc.Putting utilities into competition has led to ongoing changes in supply offers where it becomes strategic for end users to manage the annual load profile at their facility.Harmonic currents create significant additional power losses and contribute to increase power consumption.

MeasuringAll Transparent Ready products are de facto metering units for currents, voltages and power energy (e.g. Power Meter, see Transparent Ready products).Some of them have a long term recording capacity (e.g. EGX400 for historical data recording, see Transparent Ready products).

ImpactShort term issuesb Knowledge of consumption: measuring power consumption, power and current levels, to get a better idea of when and how energy is consumed, all year long. Moving consumption towards cheaper rate periods then becomes possible. Some power consumption can be postponed without disturbing productivity and without reducing occupant comfort, by managing current consuming devices using an automatic control system.

Example: commonly, this solution is applied for the production of hot water with storage water heaters as well as for storage based electric heating systems.Another application: in some countries, large amounts of ice produced during low price periods are used by refrigeration systems for air-conditioning.

b Minimising electricity costs in real time: disconnecting certain feeders to avoid exceeding the chosen consumption threshold.b Monitoring trend curves: observing power consumption trend lets us estimate when there is a risk of exceeding an authorised maximum limit.In the same way, it is possible to plan when it is necessary to change the rating of switchgear (e.g.: Multi 9 compact circuit breaker).b Managing sources: if the company has a second independent source, such as a backup generator and peak-time supplies are costly, it is possible to limit consumption during this period by switching part of the installation onto this second source (generator sets).This ensures that contract limits are never exceeded, reducing overall power costs.In any estimated economic analysis, it is therefore useful to know the cost of the substitution power, for instance generator set yield and the cost of fuel consumed.This substitution of electric power supplied by a utility with power produced on-site will very often be most favourable during the most expensive periods, depending on the supply contract. The economic advantage derived from implementing an internal power source cannot be separated from another very important advantage: the ability to react to an interruption in external supply and to maintain key services.

Example: a French company has implemented several backup generators at the headquarters of a major bank, installed in the Paris La Défense business district. Each set has a capacity of 1250 kVA and one of them is regularly used during peak times. It supplies 800 kW, two hours in the morning and two hours in the afternoon, during the four winter months.

b Optimising reactive energy: by using a power factor correction equipment in order to eliminate penalty charges (which also has the effect of reducing power losses).

DB

1077

Energy-power

DB

1077

86

Long term issue: recording the load profileGenerally over a one year period. The load curve allows us to visualise the current or power as a function of time and therefore to see how high peak consumption is and how long it lasts.

b Power contract negotiationRecording consumed power and load curves has several advantages:v optimising the power contract. When you know your consumption, you can check the suitability of the electrical power supply contract. If it does not match requirements, the company can request a change of contract, which will avoid paying too much compared with its consumption or paying penalties for days with high consumption. Your load profile represents strategic information for "tunnel" type contracts (contracts limited in terms of minimum and maximum consumption set contractually for certain times of day)v aggregating costs. For example by installing a device at each facility, overall consumption is available and negotiating the right contract becomes easier. Aggregating costs also involves having power meters for significant loads and for the main power incomer (e.g. the incomer to a Low Voltage switchboard). By arithmetic substraction, it is then possible to monitor consumption of auxiliary loads on the application. Multiple facility aggregation makes it possible to negotiate a single contract covering several remote facilitiesv identifying available power reserves when extending electrical installations or avoiding penalties for exceeding consumption.

DB

1077

87

Example: the figure shows the change in the load curve and the subscribed power values. The limit not to exceed is the threshold when the higher contract becomes financially more interesting:v a winter subscription of 360 kW seems to be slightly over-sized because there are very few times when consumption exceeds this level between February and March. The optimised estimate of the subscription threshold for winter is 340 kW, however potential savings are too low to warrant any change to the "winter subscription threshold"v the summer subscription of 540 kW seems slightly under-sized because there are a few times when it is exceeded during June, July and Augustv however the months of April, May, September and October have consumption that is well below the subscribed power level for the summer period (540 kW)v we observe that there is a gradual reduction in the active power taken from the month of March through to the month of May. This reduction is probably due to the gradual reduction in need for lighting and certainly for several convector heaters in the plant as daylight hours grow longer. Only sub-metering will allow us to validate this hypothesis.We can see a sharp increase in power from May 26, which then drops back during September. This increase is certainly due to the starting up of air-conditioning in the plant.

bbbb Internal consumption allocationSub-metering allows allocating consumption.Metering electrical power consumption for each significant power consumer by production line, by department, by product in order to allocate electricity costs.

Example: shopping centres, rented office space.

Productivity efforts on-site are measured by significant load (machine, workshop, entire facility, subsidiary) and by comparing equivalent periods or equivalent loads at different facilities.Allocating consumption to a production cycle allows us to analytically allocate the cost of a product at the end of its cycle by recording power measurements at the start and at the end of production.

Power factor and cos ϕ

DB

1077

88

The cos ϕ corresponds to the phase angle of the voltage relative to the current for signals of the same frequency. Power Factor (PF) is the ratio of real power P to apparent power S. (IEC definition).

PF is equal to cos ϕ only under purely sinusoidal conditions, i.e. when no harmonics are present.In case of harmonics, PF = cos ϕ / (1+THD2)1/2. THD (1) is significant for PF only when non-linear loads are present (variable speed drives, UPS, computers, etc.).Consequently, power factor is the most complete quantity but the separate measure of cos ϕ and THD is recommended to better decide how to correct the PF.

(1) THD: Total Harmonic Distortion.

OriginCos ϕ is less than 1 for non-resistive loads, either inductive (motors or fluorescent lamps), or capacitive (capacitors).

MeasuringVoltage and current metering unit to compute power factor and cos ϕ.

Example: Varlogic, Power Meter, etc. (see Transparent Ready products).

ImpactAs the power supply contract from an energy provider is based on real power, the less reactive power is consumed by the site the less apparent power has to be delivered by the energy provider, and the lower is the line current.Low PF can also be due to harmonics.The PF value not to exceed depends on:b the limit set by the electrical power supplier leading to contractual penalty awarded by the utilities who want to prevent the supply of excessive power related to a cos ϕ that is too low. This excess power leads to additional loss effect (temperature rise) on distribution cables managed by the utilities.

Example: cost in France is €1.754/kvarh for kvarh in excess of 0.4 x kWh.

b the main circuit breaker adjustment, in terms of tripping. This tripping is imposed by the power supplier within the framework of certain contracts (France: yellow tariff) rather than tripping related to installation protection.

Impact of cos ϕ on the available active power: this graph shows the change in available active power for various cos ϕ values, for a given apparent power.

Example: for a cos ϕ of 0.8, the available active power will be no more than 800 kW.

Improving power supply availability 0

Improving power supply availabilityWith Transparent Ready, you anticipate production stoppage.Transformer overloads, phase unbalances, motors exceeding their running time among other faults can cause production facility downtime. Finding out about possible malfunctions allows you to anticipate faults in your power supply and therefore improve its availability.

Continuity of service is a key issue. By monitoring the installation, managers opt for preventive maintenance, which is much more flexible and less costly for the company than curative maintenance.

Different benefits of monitoringChecking that the installation operates at its rated levelb Checking that the main electrical values (I, U, f) are at their rated level and that the installation operates normally. b Extrapolating the short and medium term changes to avoid reaching alarm levels or protection device trip levels.

Checking device and machine availabilityBy knowing the position of circuit breakers (open/closed) or source switches (normal/backup), the level of charge of UPS battery, the readiness of motor starters or variable speed drives, the temperature of transformers, the number of connected capacitor banks, etc.

Checking the quality of power and its impact on the installation or processb Avoid premature ageing of equipment related to temperature rise caused by harmonics (cables, transformers, motors).b Avoid equipment destruction due to transient overvoltages and vibrations, reduced continuity of service due to protection tripping, neutral overloading, etc. b Avoid production stoppages leading to non-quality rejects and major financial losses.

Example: in a paper mill, a voltage drop can generate a torque surge and rip the paper roll. In processes such as machining, or glass fiber production, incorrect voltage quality will have an impact on the finished product quality.

Current defects

Current defects, such as unbalance, high current in the neutral conductor and high inrush currents, can be the source of malfunctions in the electrical network.

DB

1077

92

Current unbalanceHigh current in the neutralThere is a current unbalance when the phase shift between the phase currents is not equal to 120˚ or when the rms values are not equal. High current in the neutral conductor is generally due to a current unbalance or the presence of harmonic currents of order 3 (and multiples of 3).

Originb Current unbalance is due to incorrect spread of single phase loads between the 3 phases.b Third harmonic currents are generated by single-phase non-linear loads such as IT equipment, variable speed drives, UPS, battery chargers, etc.

Examples of current (voltage) unbalance.

DB

1077

93

Measuringb phase currentsb neutral conductor current (when neutral is distributed)b unbalance level (directly available on CM and Micrologic P and H : see Transparent Ready products).

ImpactHigh values of neutral current can produce neutral conductor overload, particularly if the neutral conductor is half-sized compared to the phases.Current unbalance produces voltage unbalance which can be harmful to motors (additional power losses, vibrations).

19



Current defects

Inrush current A high transient current: when an electrical device like a transformer is energised (for 0.2 to 2 seconds).This short duration phenomenon is not displayed on the Web pages of the standard Transparent Ready products other than through the recording of the max. current level but it is available from dedicated tools for electrotechnical experts.

OriginEnergising of transformers, motors starting, connection of capacitor banks or lighting ballasts.

DB

1077

95

MeasuringBy metering unit (possibly wave capture with logging), by measuring the max current.

Example: Micrologic H (see Transparent Ready products).

As short duration current phenomena are very specific, they require the knowledge of an electrotechnical expert.The usual way to analyse these phenomena is to capture the wave forms for off-line analysis using a dedicated software tool.For this reason the Transparent Ready standard offer does not include dedicated Web pages but allows the transmission of the complete data over the Intranet.

Example: wave form capture by Sepam, PM850, Micrologic H, CM3000 (see Transparent Ready products) and transmission of data through the Intranet to SMS software for expert.

Voltage

Voltage defects can be the source of malfunctions in the electrical network.For example:b voltage variations outside of a ±10 % band around the rated voltage (including voltage dips)b voltage interruptionsb voltage distortion (harmonics)b transient overvoltagesb rapid voltage changes (producing flicker)b voltage unbalance.

Originb Overvoltage can originate from over compensation of reactive energy, the loss of neutral conductor or a fault affecting the energy provider regulation system.b Undervoltage can be due to the energy provider's distribution line becoming overloaded or the starting of large motors.b Voltage dips are short duration undervoltages, generally caused by faults occuring in the network user’s installation or in the public distribution system.b Transient overvoltages are mainly due to capacitor banks switching or lightning discharge.b Rapid voltage changes are produced by rapidly fluctuating loads such as arc furnace or large motors (elevators, wood choppers, etc.).b Voltage unbalance is the result of the circulation of unbalanced currents, due to unsuitable spread of single phase loads

Measuringb Current, average and maximum voltage phase-to-phase or phase-to-neutral levels.b Unbalance voltage as defined by IEC standard (Negative sequence voltage / positive sequence voltage).b As short duration voltage phenomena are very specific, they require the knowledge of an electrotechnical expert.The usual way to analyse these phenomena is to capture the wave forms for off-line analysis using a dedicated software tool.For this reason the Transparent Ready standard offer does not include dedicated Web pages but allows the transmission of the complete data over the Intranet.

Example: wave form capture by Sepam, PM850, Micrologic H, CM3000 and transmission of data through the Intranet to SMS software for expert.

Impactb Overvoltage: can result in equipment premature ageing or even failure.b Undervoltage: makes motor starting more difficult as the starting torque is reduced. The permanent current absorbed by motors is increased, which may result in overheating and tripping of protection relays.

Long or short interruption Supply interruptions are characterized by a total loss of supply voltage and duration:b < 3 mn: short interruptionb > 3 mn: long interruption.

OriginLong interruptions of supply by the energy provider are whether prearranged for the execution of scheduled works or accidental, generally the consequence of bad weather conditions.Short interruptions of supply are the consequence of fault clearance and automatic reclosing of circuit breakers. Interruption can also originate from failures inside the user’s installation: cable failure, loosening of terminals, short-circuits.

MeasuringPhase-to-phase voltages with recording over time.

ImpactSupply interruptions can have a large diversity of consequences: simple momentary discomfort, loss of production, loss of valuable data, destruction of production tools, danger of life.

Short interruption.

Harmonics

DB

1078

01

HarmonicsHarmonics are present when voltages and currents have distorted, non-sinusoidal waveforms.

OriginHarmonic currents are generated by non-linear loads, i.e. loads that draw current with a waveform that is not the same as that of the supply voltage.Harmonic voltages are the consequence of the circulation of harmonic currents through the system impedance.

Example of non-linear loads: rectifiers, variable speed drives, UPS, office equipment (computers, servers, photocopiers, ...).

The Total Harmonic Distortion (THDu (1) for voltage, THDi (1) for current) characterizes the waveform distortion.

THDu THDi Interpretation< 5 % < 30 % Value considered normal. No malfunctioning should occur.5 to 8 % 30 to 50 % Shows significant harmonic pollution.

A few malfunctions are possible.> 8 % > 50 % Reveals major harmonic pollution.

Malfunctions are probable.In-depth analysis and fitting attenuation devices is necessary.

(1) THD: Total Harmonic Distortion. THDi: in current. THDu: voltage.

MeasuringTHDu and THDi instantaneous and maximum values with power measurement units.

Example: PowerLogic devices such as Power Meter, Circuit Monitor. Included in Micrologic H protection dedicated to Masterpact and Compact.Use of SMS analysis software for expert is recommended for wave form capture by harmonic range.

Impact

DB

Devices EffectsPower capacitors Heating, premature aging (breakdown), resonance.Motors Losses and additional heating. Reduced ability to run at full

load. Oscillating torque (vibration, mechanical fatigue). Audible nuisance.

Transformers Losses (heat-iron) and additional heating. Mechanical vibration. Audible nuisance.

Circuit breakers Nuisance tripping.Cables Additional dielectric and heat losses (especially neutral losses

when third order harmonics are present).

Example: conductor power losses.The following features are shown in the next figure, as a function of THDi:b the increase in rms current, Irms, for a load absorbing a given fundamental currentb the increase in heat losses, Pj, without taking into account the skin effect (taking base 1 as reference on the graph for Irms and Pj in the case where there are no harmonics present). Therefore, harmonic currents generate an increase in losses expressed in Joules from all conductors and additional temperature rises in transformers, switchgear and cables.

In the case of THDi > 50 %, the recommendation is to consider significant load losses increase and that consequently transformer temperature rises exceeding those corresponding to sine wave currents with the same rms value.Refer to the current section on how to take into account the effect of current harmonic pollution.

Better managing of your electrical installation 0

This objective can be reached through monitoring the following aspects.

Electrical network day-to-day operationNumerous operators on-site, electricians, production supervisors, facility managers, need to know the situation of the equipment at any time. The status of breakers or other power devices is a very commonly required information.

Preventive maintenanceThe electrical equipment requires maintenance operations in line with manufacturer's recommendations.Typical parameters often used are equipment temperature, running hours, insulation levels.

Example: the number of running hours of a motor, the number of switching operations for a circuit breaker.

Tailored investmentb Checking that electrical values do not exceed the maximum permissible values given by the manufacturer makes it possible to guarantee the equipment’s service life.b Identifying the available reserve power makes it possible to better manage future investment in electrical equipment.b The same applies to identifying the average load level according to production cycles, seasons, etc. and deducing the available power for new current consuming devices.

Having the real technical information available gives credibility when increase of the power capacity has to be decided.

24



Temperature

DB

1078

02

Temperature is a parameter to be taken into account because it is closely related to the electrical switchboard load and environment.

OriginExcessive temperature is revealing an overload, incorrect connections (not complying with tightening torques) or poor electrical cabinet ventilation.

MeasuringMetering units with temperature probes.

Example: Power Meter or Sepam options (see Transparent Ready products).

ImpactThe main impact of uncontrolled temperature is reduced equipment service life (motor, transformer).Apart from electrical or mechanical faults, the service life of electrical equipment is limited by the temperature its insulation is subjected to: the higher it is, the shorter the service life. Tests carried out on a large number of power devices have shown that the service life of a device is reduced by around half every time the temperature increases by 10 ˚C (outside of its operating temperature range).

Example: an electrical device with a service life of eight years and an operating temperature of 105 ˚C:In this example, the service life of the device falls from eight years to one at an operating temperature of 135 ˚C instead of 105 ˚C.

Example: IEC standards 60-905 and 60-354 define the impact on the service life and on the operation of power transformers (cast resin and oil-immersed types) outside of their maximum service temperature limits.

DB

25



Insulation resistance

Insulation faults lead to leakage current between phase and earth.To avoid a tripping, an IT isolated neutral system is prefered.

Example: operating room in hospitals.

OriginAging cables, accumulation of conductive dust on busbars or terminal boxes.

MeasuringFor IT isolated neutral system: permanent insulation monitoring.

Example: Vigilohm system (see Transparent Ready products).

This measurement is carried out with direct current. The insulation resistance must be measured between each active conductor and earth.Minimum values of the insulation resistance (regulatory thresholds):

Circuit rated voltage (V) Insulating resistance (MΩ)Very low safety and protection voltage levels 0.25Not exceeding 500 V, except in the cases below 0.5In excess of 500 V 1.0

Insulation is generally checked first as far upstream as possible in the specific installation. If the insulation exceeds the value specified in the table, installation insulation is correct.If the measured value is less than that specified in the table, the insulation resistance of each circuit must be measured until the feeder(s) with low resistance is(are) located.

ImpactOn the following equipment: circuit breaker, permanent insulation controller.

26



Number of Switching operations and operating duration

DB

1081

45

Every piece of equipment is designed for a certain number of switching operations, or for a certain service life.The number of successive direct on line start-ups of motors depends on the driven load characteristics (torque curve as a function of speed, inertia). Repeated start-ups increase the motor temperature as well as the strain on the machine. This shortens the service life and can even lead to failure.For more information on the number of authorised consecutive start-ups, refer to the machine characteristics or consult the manufacturer.The load characteristics must be known in order to determine the start-up frequency.If continuity of service is a key requirement, the number of past start-ups may be used to plan preventive maintenance.

MeasuringProvided by metering units, variable speed drives, UPS devices for battery maintenance, etc.

ImpactThese quantities must be taken into account in the equipment maintenance policy, especially when forecasting procurement and replacement during shutdown periods.

Transparent Ready electrical networkThe Transparent Ready solution supports power value retrieval via the EGX400 Web server and the Internet browser and enables them to be used with a Microsoft© ExcelTM type spreadsheet. The power curves can then be plotted in real time by the spreadsheet.No IT investment, whether hardware or software, is needed to access the data via the existing office network.The metering devices also allow measurement of basic electrical parameters as well as briefly checking the quality of electrical power.When used in the commercial sector, PM710 can be replaced with PM9C. According to applications, PM9C may be sufficient. In this case the overview of power quality is not available and the unit is only mounted on a DIN rail.To reduce the electricity bill and limit evening and weekend consumption, the trend curves provided by the PM850 should be studied (see Transparent Ready products).The two figures below show the change in load curve before and after actions intended to reduce the electricity bill.These curves are focused on the change in evening and weekend power levels.

The first way in which we can act involves detailed analysis of measurements. The reports and the consumption curves allow this analysis to take place. These documents help us to detect abnormal consumption.In our example, this involves checking if the consumption drops normally at night or during weekend.Here, consumption during non-opening hours seems excessive, as a result, two decisions were taken:b reducing lighting at nightb switching off air-conditioning during weekends.The new curve obtained shows a significant drop in power consumption.

Case 2 - Tertiary building siteBiotech SA develops software for simulating the effect of drugs used to fight certain human illnesses. It employs external consultants for each kind of drug. An experimental laboratory is used for software validation. It is located in a 20-storey building including the R&D department, the laboratory, support functions and executive management.Following unexpected power outages with expensive consequences, the company decided to replace its existing electrical equipment, and to have a backup power supply as well as having a real-time monitoring system for the electrical situation.

Transparent Ready electrical networkTransparent Ready is integrated into the building’s Intranet infrastructure.The basic values are monitored: current, voltage, frequency, power and energy.For the main circuit breaker: we also have the date-stamped event function, as well as continuous harmonics measurement, order by order.

For the feeders (see Transparent Ready products):b PM820: date-stamped alarms, particularly suited for motor type current consuming devices with a process that is sensitive to power outagesb PM9C: basic values.

Note: the date-stamped alarm function can be achieved with a PM810 combined with a PM810log module which adds an 80 kB memory (which notably allows recording the time and measurements in a data log).

By replacing the PM820 with a PM850, the user also benefits from trend curve and wave form capture functions, for example when an alarm threshold is exceeded.Certain Schneider Electric Web servers allow maintenance staff to be informed of any operating anomaly. To do this, they send historical data or alarms generated by the metering units or by the Masterpact or Compact circuit breakers, by e-mail and text messages, via the Internet service provider.The CM4000 allows verification of EN 50160 conformity as well as the detection and capture of transients of less than 1μ second. It is also equipped with the D.D.D. ("Direction Disturbance Detection") function which records the direction of disturbances, in other words determining whether the disturbance was generated by the facility or the supplier.Sensitive feeders can also be equipped with PM850 enabling wave form capture as well as harmonic content, order by order. A CM3350 is justified by the ability to detect voltage surges and drops.A feeder that is not very sensitive is equipped with a PM700 in order to find out the harmonic distortion level.

Case 3 - Multiple locationsFourcar Inc. is a worldwide consumer products retailer (food, textiles, hardware, etc.), with supermarkets in major urban areas.Constantly searching for productivity gains to highlight its greater financial appeal over its main competitors, this company wants to improve the power performance at its locations and is interested in setting up benchmarking between them in terms of power consumption. It is considering assigning this task to Facility Manager partners chosen by country or region.The company wants to get a management chart to consolidate results on a worldwide scale.The chosen Facility Managers, in charge of all energy consumed on-site, water, gas, fuel, electricity, have to call in an electrical distribution specialist to analyse the data.

Transparent Ready electrical networksTransparent Ready is integrated in the company’s Intranet infrastructure. Site by site, building by building, electrical switchboards are connected to the Intranet to provide key electrical data.

DB

08

On a worldwide level, according to access authorisation rules for the company’s own information and implemented by the company’s IT manager, each electrical switchboard becomes accessible via a simple Internet browser, without any IT investment, either hardware or software.By country or by region, the electrician's team in charge of electrical power availability at several locations can already consult this data remotely without wasting time on transport: they simply have to connect a PC from anywhere on the Intranet.The Facility Manager or the IT expert can access electrical data, yet the company's IT managers forbid any Intranet connection by anyone from outside of the company: this is the most common security policy intended basically to avoid introducing viruses.Sending data out from the Intranet is however allowed.Data can be regularly captured in electrical power spreadsheets stored in a PC at the company and sent by e-mail to the Facility Managers or to the expert electricians, at a preset frequency (daily, weekly, etc.)The Schneider Electric Services e-Analysis offer includes all of these functions to which we can add the provision of a Web portal where the Facility Manager or the company can access the expertise of our electrical network specialists. This expertise is focused on analysing electrical power consumption, power availability and optimising operation of electrical equipment.

Summary

More and more, end user has no time to investigate the electrical network.In some cases the skilled electrician staff is so reduced than minimum operation and regular maintenance are not done, causing unexpected events on the electrical distribution. Consequences can be dramatic in terms of safety and costs, even become a nightmare.

Schneider Electric services activity propose a comprehensive approach to support you in the management of your electrical installation energy and so improve electrical energy efficiency.e-Services are a key component of this approach for installation performance follow-up, equipment ageing assessment, power quality monitoring and energy consumption costs savings.

This section develops the e-Services that Transparent Ready solution make available, either for medium-size site or for large site, to support the maintenance activity and ensure the performance of your electrical installation. The main principles are the following :

b

as your electrical network is Transparent Ready, that means electrical data can be pushed to a e Services internet Web platform then these data can be analysed by expert people to detect abnormal trends or thresholds

b

historical data hosting

b

a Web site allows access to main indicators on energy efficiency, as well as report made each month or quarter depending on your expectations.

Data confidentiality and network security are concerns we have taken into account to build the technical solution. These issues are addressed in the IT section of this document.

Services approach & Transparent Ready e-Services

The first step is a diagnosis of your installation. This diagnosis assesses the following points:

b

the reliability of electrical network architecture

b

the performance, ageing and operational conditions of each piece of equipment

b

the organisation of operation and maintenance activity.The result is a proposed plan for maintaining and monitoring the installation.The monitoring plan identifies the data requested for managing the maintenance plan (number of operations, trippings, load, temperature, levels of harmonics, etc.) and where you need to collect data, based on the reliability analysis of the network architecture.On top of that, this plan also identifies the main consumers and therefore where measurement devices should be installed to perform a relevant consumption analysis.The second step comprises implementing these plans.Although defining a maintenance plan is broadly recognised as a key success factor, implementing a monitoring plan is still considered as "icing on the cake" and this is a big mistake. A maintenance plan remains theoretical and irrelevant without a continuous feed of "live" data from the equipment. In addition, you will never be able to identify real cost savings without accurate data. Up to now, main issues were related to the technical complexity regarding both system installation and data analysis. Thanks to Transparent Ready barriers to implement e-Services have been removed:

b

simple installation: as your network is Transparent Ready data can easily be sent towards a remote e-Services platform

b

progressive implementation: you can start with few communicating devices and progressively extend the system in order to more accurately or broadly cover the installation

b

flexibility: you can choose your policy, either ask Schneider Electric to analyse the data or ask one of your partners to do this, do it by yourself or apply a combination of these options. For example, you could decide to perform energy management by yourself, ask a partner to perform power quality monitoring and rely on Schneider Electric to ensure asset performance/ageing follow-up.

DescriptionThe Canalis high power busbar system has been designed to feed and distribute high power in industrial, commercial or service buildings from 1000 A up to 5000 A for three-phase and neutral power distribution needs. Canalis 250 and 400 A taps for billing and measurements are useful for KT and KS two-level busbar systems.They are equipped with a Power Meter 810 U, a Compact NS with CT that is used to protect and monitor the line. Taps that allow sub-billing with cost allocation and monitoring for secondary lines are connected through a Modbus communication serial link to the Transparent Ready solution.If a switchboard is located downstream or upstream from the high power busbar system, then fit the PM in the switchboard for practical reasons on-site, and not on the tap.The KBA busbar system is used not only for facility lighting but also to supply the PM810 and to wire the Modbus serial link cable.

Description

The Transparent Ready solution is based on finding the right way to capture fundamental quantities, especially current and voltage measurements.Current or voltage transformers between Medium or Low Voltage power lines and measurement products (measurement units, speed drives, UPS systems, etc.) or protection systems (protection relays) are designed to:

b

reduce current and voltage values to levels that are compatible with the products used. These standardised transformers provide the products with a true image of the current (or voltage) values involved

b

uncouple these products with respect to the voltage levels present on the electrical networks, whether permanent or transient ones. Earthing the product is possible (except for devices with inputs that are not insulated), thereby ensuring user safety.

Choosing current transformers (CTs)

The choice of an instrument CT is dependent on the transformation ratio Ip/5 A and the type of installation. It is also necessary to make allowance for the load accuracy class, the accuracy power and the accuracy limit factor.

Example: Merlin Gerin CT transformer characteristics:

b

transformation ratio: 40/5 A to 6000/5 A

b

accuracy: class 0.5 to 3

b

maximum rated operational voltage: 720 V AC

b

standard or tropicalised.

Beware of the fundamental differences between instrument CTs and protection CTs: substituting one for the other is not possible on a given product.Refer to the Merlin Gerin "Electrical Installation Guide".

Example: when a Transparent Ready protection product communicates a current or power measurement, its accuracy remains way below the values communicated by a Transparent Ready measurement unit.

Choosing voltage transformers (VTs)

A voltage transformer (VT) is designed to provide the secondary winding with a voltage level that is proportional to the one applied to the primary winding.These transformers are used when the voltage level that can be measured by the measurement unit is not compatible with the supply voltage.A VT is especially characterised by: primary voltage, secondary voltage, apparent power, operating frequency, accuracy class.

In addition, the optimised size of these products are ideally suited to the size of enclosures used for distributed Compact or Multi 9 systems located in the distribution cabinet. This solution reduces cabling time and cost required to gather circuit breaker status data (digital inputs) and at the same time takes into account the modular architecture of the distribution network.It includes Modbus RS 485 serial link communication. Each base incorporates 12 inputs to energise with 24 V DC. Two inputs are used by a Multi 9 or Compact device (circuit breaker, switch, etc.), one for position, one for status. TwidoSoft is needed for time stamping of the inputs and for sorting the time stamped data in the Modbus table.

TR Web server

Selection guideThe Transparent Ready solution is based on the use of Ethernet TCP/IP communication technology and related software services, the so-called Web. From among these Web services, e.g. Modbus on TCP/IP, e-mail, Web pages, file transfer, time synchronisation, etc., Transparent Ready proposes a dedicated use of Web pages: the HTML service.Through a set of pre-defined HTML Web pages dedicated to electrical distribution and embedded in the MV and LV power equipment, end-users can immediately take advantage of electrical network monitoring from their own Web browser.These HTML Web pages are stored in a Web server connected to measuring devices like the Power Meter or to Altivar speed drives. A standard offer with support for customisation is possible:b as standard, the EGX400 and MPS100 or ECC21 Web servers offer pre-defined Web pages. Electrical data is displayed immediately and no software development work is required. This is the most cost effective solution.MPS100 is dedicated to Micrologic systems and Power Meters while EGX400 offers a wider choice of equipment that can be monitored. ECC21 is embedded in PowerLogic Circuit Monitor with a reduced set of Web pages, i.e. the same circuit summary pages as EGX400b if the application requires custom Web pages, the Telemecanique ETG1000 multi-purpose Web server can be customised by the system integrator. Additional cost will be incurred to create and test the customised Web pages.Where HTML Web pages are not needed, but only a direct access to data in Transparent Ready products, you can install a router: the router converts the Modbus serial link into an Ethernet Modbus TCP/IP link, e.g. EGX100.

Note: Web servers include router capability but the reverse is not true.

Electric power experts use a disturbance analysis software such as PowerLogic SMS or an overall control system (Scada) where a simple router is the right solution.

DescriptionConneXium is the Schneider Electric rugged solution for Ethernet cabling systems especially supporting Modbus TCP/IP. ConneXium products are adapted to electrical distribution and can be mounted on a DIN rail.

ConneXium hubs - passive concentrators to connect Ethernet usersHubs are used for transmitting signals between several ports. Hubs make it possible to create different topologies.

ConneXium transceivers - active device used to create Ethernet subnet in order to optimise response timeConneXium transceivers make it possible to interface products using twisted pair cable Ethernet connections and fibre optic cables. ConneXium transceivers provide fibre optic connections for transmission in areas subject to interference (high levels of electromagnetic interference) and for long distance communications.

ConneXium switchesSwitches are used to increase the limits of architectures based on hubs or transceivers, by separating collision domains (filtering). Certain ConneXium switches also enable redundant architectures to be created on twisted pair copper or fibre optic rings. They can also be remotely administered using SNMP or HTTP protocols for monitoring and diagnosis purposes.

ConneXium connection cablesConneXium shielded connection cables are available in two versions to meet current standards and approvals:b standard EIA/TIA 568 shielded twisted pair cablesb UL and CSA 22.1 approved shielded twisted pair cables. Their fire resistance conforms to NFPA 70.ConneXium provides two glass fibre optic cables for connection of terminal devices to hubs, switches and transceivers.

Cabling systemRS 485 connection

Typical design DescriptionTechnical characteristicsThe physical transmission systems used by Transparent Ready products to send data are EIA RS 485 standard compliant.As standard, only "two-wire" cabling is offered here as it has proven its efficiency in industrial environments.The RS 485 cabling architecture proposed in this section is suited to switchboard needs, for electric power distribution switchboards and motor control switchboards: bus length limited to 1200 meters, total tap length limited to 40 meters, with one meter per tap recommended.The transmission line uses a bus topology and must be "impedance adapted" to limit the distortions to transmission signals from high frequencies signal propagation phenomena. This means that the transmission line must essentially comprise a "trunk line" with a characteristic impedance of 120 Ω, terminated at each end by a "line termination impedance" Rc of 120 Ω. Taps from this trunk line (the stub lines) must be kept "short".

RS 485 polarisationThe effect of polarisation is to continually carry a current through the network, imposing an idle state on all loads. It must be unique on the bus. We recommend using the Modbus master's supply and Rp polarisation resistors.

Note: the EGX400 web server handles polarisation: In practice, the two wire RS 485 link requires a third wire for the common line, separated from the shield and connected to earth at both ends.

A 24 V supply pair is added to the bus pair in the same cable to supply some of the communication devices: the Sepam interface and Micrologic communication module. The Modbus 0 V common line is also the 0 V level for the 24 V DC supply.

Using RS 485 to connect productsSchneider Electric offers various methods for connecting Transparent Ready products to the EGX400 Web server via an RS 485 Modbus communication link:b a dedicated ACE interface for Sepam protection relaysb Phoenix terminal blocks for direct wire connection using screw terminal blocksb CJB306 junction boxes with Sub-D9 connectors and built-in terminal blockb Modbus LU9GC3 splitter block with RJ45 connectors.

Case 1: dedicated ACE interface for Sepam protection relaysThis active interface is required when using Sepam Series 20, 40 and 80 devices.Different versions are available including the ACE949-2 interface(refer to the Sepam documentation).The ACE949-2 interface performs two functions:b the electrical interface between the Sepam device and a two wire RS 485 communication networkb serving as the network cable connector box for connecting a Sepam device with a CCA612 cable.If the interface is on the end of an RS 485 network, a jumper can be set for line-end impedance matching with load resistor.An external 12 V DC or 24 V DC ±10% supply is required.If no Transparent Ready products from other ranges are connected to the RS 485 link, the EGX400 Web server will be directly connected to the first ACE949-2 interface.

Typical design Case 2: Phoenix terminal blocks for direct wire connection using screw terminal blocksPhoenix offers passive RS 485 wiring terminals using daisy-chaining.Daisy-chaining is effective when connecting devices outside the switchboard, or between two switchboard columns that are separated for transport reasons.This method can however also generate wiring errors at each terminal end:Schneider Electric recommends standardising the wire colours used for the RS 485 link when producing the wiring diagrams.With CCR301 cables, the following standard is used:b data wire D1= blueb data wire D0 = whiteb shield (earth symbol) = greenb common (0 V) = blackb VP (24 V) = red.

Case 3: CJB306 junction boxes with Sub-D9 connectors and built-in terminal blockSchneider Electric recommends using CJB306 passive junction boxes for quick set-up and easy error checking as all connections are concentrated geographically at one point: do not "daisy-chain" the devices but connect each of them to the junction block.This method does however increase cable lengths between the product and the junction box in the cabinet. A 40 meter length limit must be complied with when totalling the wire lengths of all of the taps.The CJB306 junction box is used to connect up to six products, receive a 24 V DC (led) power supply, and allows configuration with RS 485 two wire connection and to terminate the last RS 485 link with an end of line resistor. It is connected to earth.The CCD303 cable between the Micrologic unit and the CJB306 also sends the 24 V DC supply required by the Micrologic Modbus communication module.The CSD309 connector is used to connect any product to the CJB306 junction block.Schneider Electric recommends the use of the CCR301 and CCP303 cables as the colour of each wire is used as a reference in section Wiring the Equipment when connecting different Transparent Ready products.

Note: To change from an RS 485 four wire link to an RS 485 two wire link with the CCR301 cable, the wiring is as follows:b In + and Out + are connected to D1 = blue and yellowb In – and Out – are connected to D0 = white and brownb earth = greenb 0 V = blackb 24 V = red.

Cabling systemEthernet plugs & wiring

DescriptionSchneider Electric, provides connector and wiring solutions for connecting PCs to Transparent Ready electrical equipment or Web servers to end user Intranet systems.b The Infraplus* RJ45 protection connector socket is specially designed for highly protected applications in the severe environments that can be found in electric power distribution applications. Made to IP67 standard, it offers full safety for industrial Ethernet applications.The RJ protection connector must be used with a shielded female RJ45 connector like the Infraplus RJ45 slim jack, FTP category 6.Patch cords are Ethernet cables equipped with male RJ45 connectors.b Schneider Electric offers a splitter block to simplify equipment wiring. When 10 Mbit and 100 Mbit connections with standardized Ethernet cable are used, only two of the four pairs are used, so the splitter block lets you use the remaining two pairs so that only one cable is required instead of two. Two Ethernet RJ45 are then available in the switchboard, one for EGX400 and one for the front panel protected RJ45 connector.

This section is intended for optimising the wiring of communicating Transparent Ready products integrated in MV & LV power equipment and the cabling of Transparent Ready equipment on-site.

Earth ground and machine ground

The role of an earth grounding network is to discharge to ground all leakage and fault currents from equipment, common mode currents from external cables, mainly power and telecommunication and direct lightning current.Physically, low resistance in relation to a distant earth ground is fewer relevant than the local equipotentiality of the building. In fact, the most sensitive lines are those which connect equipment together. In order to limit the flow of common mode currents in cables which do not leave the building, voltages between equipment interconnected at the site must be limited.Interconnecting buried networks is recommended. When the area of a building is small, i.e. approximately ten square meters, a simple buried belt is sufficient. For new buildings with a large surface area, we recommend linking buried conductors in a cage measuring approximately 10 m on each side.A machine or chassis ground is any conductive part of a device which is accessible to touch and, although not normally live, can become so if a fault occurs. The contact voltage of two machine grounds which are simultaneously accessible must be lower than the conventional contact limit voltage (25 V or 50 V as the case may be). This is fundamentally all that is important in personnel safety terms, rather than the ground resistance or the way in which machine grounds are earthed.

Electronic equipment and systems are interconnected. The best way of ensuring efficient operation is to maintain good equipotentiality between the different devices. Inter-device equipotentiality must remain satisfactory, particularly for digital equipment, up to very high frequencies:

b

in cases of incompatibility, safety rules take precedence over EMC constraints

b

in cases of incompatibility between the recommendations in this manual and specific instructions for a device, the latter take precedence.

Shielded Cables

A shielded cable provides excellent protection against electromagnetic interference, particularly high frequencies. The effectiveness of a shielded cable depends on the choice of shielding and, even more importantly, on how it is installed.

Choice of cable

The choice of shielding quality depends on the type of connection. Schneider Electric defines the cables for each fieldbus and local network so as to ensure the electromagnetic compatibility of the installation. The problem with taped cables is their fragility. The protective effect of taped cables at HF is reduced as the cable is subject to different forces, such as traction and torsion. Single braid cables are the most common minimum solution for industrial applications.From a few MHz, the protective effect can reach several hundred MHz using a single braid if the shielding connections are suitable. Flexible, strong shielding makes installation fairly simple, and is compatible with Sub-D or mini-DIN connectors.

Where should the connection be made?

Unidirectional connection of the shielding prevents LF currents from flowing through the braid. The shielding masks the LF electric field.Differential signals are thus protected in LF mode. In HF mode, this type of connection is not effective.Bidirectional connection of the shielding can be used to protect against the most severe interference: HF common mode.The problem with bilateral connections is that at low frequencies a current can flow on the shielding (voltage between the two ends or looped field coupling). This current generates a low voltage, sometimes called "hum", or 50 Hz noise, on the pair inside.Both ends of the external shielding of all digital or power connections should be connected to the machine ground at their point of entry into the equipment. Only low-level low frequency unshielded analogue connections should be connected at one end only.

Wiring rules for panelbuilders

Rule no. 1

The outward and return conductors must always be adjacent to each other. For digital or analogue signals, the use of pairs is a minimum requirement. Special attention should be paid to wiring inside enclosures which use separated conductors. The wires must be labelled by signal type and by pair. Special case: the wiring for chains of emergency stop and alarm systems must never be single wire point-to-point but in pairs.

Rule no. 2

Fastening all connections to grounding equipotential structures is recommended in order to benefit from an HF protective effect. Ideally, shielded cables or shielded multiple strands should systematically be used. Nevertheless, the use of ducts for conducting cables provides a satisfactory level of protection in most cases. As a minimum, connection cables between or within buildings should also have a grounding connection: grounding wire or cable ducts. For connections inside enclosures and machines, cables should be systematically fastened against a metal plate. In order to maintain the correct protective effect, the following ratio should be observed: distance between cables/radius of thickest cable > 5.

Rule no. 3

Only pairs used for analogue, digital and telecommunications signals may be adjacent to each other in the same bundle or laid in the same cable group. Relays, speed drives, supply and power circuits should be separated from the above pairs. When installing variable speed drives, it is important to ensure that power connections are clearly separated from data links. Whenever possible, a cable duct should be reserved for power connections in enclosures.

Rule no. 4

The same connector should not be used for connecting different families, except for relays, supply and power circuits. If the same connector is used for both analogue and digital signals, these must be separated by a row of pins at the 0 V connection.

Rule no. 5

All unused conductors in a cable should be systematically connected to the chassis ground at both ends, except for analogue cables. This provides a protective effect with a factor of approximately five in HF.

Rule no. 6

Power cables do not need to be shielded if they are filtered. The power outputs of variable speed drives must therefore be either shielded or filtered.

Electromagnetic Caging

Linking the grounding elements inside an enclosure or a small machine is essential since these elements are directly accessible to electronic equipment. All the metal structures of the bay will thus be interconnected. Equipotential connections for safety purposes must be complemented by direct connections between all elements in the machine or enclosure. Systematic use of a grid or cage at the back of the enclosure for mounting all equipment is recommended.

Warning:

most protective coatings have an insulating effect.

Installation

Protecting external connections to the equipment

Most of the problems encountered on-site are conduction related. It is essential that all wiring connections outside enclosures or machines be protected.A grounding strip or potential reference plate (PRP) will be defined for each enclosure and each machine. All shielded cables and all wiring protection systems outside that enclosure or machine should be connected to it. This PRP can be one of the metal plates of the enclosure or its DIN cage. The PRP should always be connected to the electromagnetic caging of the enclosure or machine and to that of the equipment group. In plastic enclosures (not recommended), a DIN rail or grounding terminal should be used.Connecting shielded cablesThe way in which shielded cables are connected directly determines the HF protective effect. If the connection is made using a "pigtail", i.e. a single wire, protection is no longer provided at HF levels. A shielded fixed connection through the wall using a metal cable gland is the best solution, providing the paint is removed in order to ensure good electrical contact. A jumper can also be used, to ensure contact over at least 180˚.

DB

1080

89D

B10

8090

Using cable ducts

Cable ducts outside enclosures must be made of metal if over three meters long. These ducts must have end-to-end electrical continuity and be directly connected to the grounds of enclosures and machines using trunking joints or connection bars.Any other cable should only be used in cases where no other solution is possible.If a single duct is used, it must be no longer than 30 m if possible. Unshielded cables must be fixed in the corners of the ducts as shown in the figure below.Vertical separation in the duct avoids mixing incompatible cables. A metal cover on signal half-ducts is recommended. It should be noted that a full metal cover on the duct does not improve EMC.

DB

1080

91D

B10

8092

Example: shielded digital connections less than 300 meters in length, without analogue cables. As soon as the length calculated for an installation condition is no longer sufficient (100 meters in the first example), the configuration's EMC must be improved.

A vertical separation in the duct is used to avoid mixing incompatible cables. A metal cover on the half-duct of signal cables limits the interference from signals.The EMC conditions to be observed are thus:

b

each half-duct is no more than 50 % full

b

the separation is made of metal and in contact with the duct throughout its length

b

the cover is in contact with the separation throughout its length.Make allowance for possible future developments.

Connections between buildings

They have two characteristics which can result in risks for the installation:

b

poor equipotentiality between the grounding elements of installations

b

large loop areas between data cables and grounding elements.Before installing and connecting a data cable between two buildings, it is essential to check that the two ground connections of the buildings are interconnected.All grounds which are simultaneously accessible must be connected to the same ground connection, or at least to a set of interconnected ground connections.This constraint is fundamental for the safety of personnel. The second risk related to connections between buildings is the loop area between data cables and grounding elements. This loop is particularly critical in the event of an indirect lightning strike on the site. The overvoltages induced in these loops through indirect impact of lightning are in the order of a hundred volts per square meter. In order to limit this risk, all cables laid between two buildings must be duplicated by a large-gauge equipotential connection (Ø 35 mm

Checking communication links in electrical devices

This section presents the general approach to implementing communication links between Transparent Ready products: rigorously applying these principles makes it possible to avoid a first source of errors and time lost due to communications that do not work.Refer to the product documentation for detailed information on configuration and wiring.

RS 485 Modbus serial link

All products must be configured and wired identically.Configuration: transmission speed at 19.2 kbauds, even parity.Wiring: RS 485 two wires link, line adapter resistor and polarisation supply depending on the product, the Bus+ and Bus- wires are not grounded, shields are grounded.Line termination: fit a termination resistor at the end of the daisy-chain.

Ethernet TCP/IP

Connect a PC to an EGX400 with a cross connected Ethernet cable.Force PC Ethernet communication by setting an IP address and subnet mask that are compatible with the workshop. Set EGX400 configuration (using Start > Connections > TCP/IP Properties with Windows XP).Check the Ethernet TCP/IP link with the EGX400 connected on the workshop Intranet.

EGX400

b

load the Web pages using WPG, the EGX400 configuration tool

b

configure the serial ports

b

configure the list of products connected, one by one

b

connect a single product to EGX400 and check one device at a time

b

check the EGX400 Web pages by sending voltage and current levels to the Transparent Ready product.

Example: panelbuilders check the RS 485 and Ethernet transmission links and measure them at the shop. This way they can issue a factory inspection report.

Final on-site inspection

Ethernet TCP/IP

To connect the EGX400 to the facility Intranet: the facility IT manager provides a fixed IP address, a subnet mask and the address of the default gateway:

b

fixed IP address: a unique address for each EGX400. It is "fixed" insomuch as the IT system that automatically assigns IP addresses (the DHCP service) for each new connection to the Intranet, e.g. on power up, does not have to assign it an available address

b

subnet mask: linked to the IP address, this number identifies the LAN segment where the EGX400 is located

b

default gateway: the address of a local IP router located on the same LAN segment and that is used to send the traffic towards destinations located beyond this LAN segment.

Checking the measurements in real life

Power up the electric switchboard in line with the applicable safety requirements and check the values on the Web pages.The complete measurement sequence is factory tested, all you need to test is the power part of the MV or LV switchboard.

Glossary 89

Summary

This section develops the means used to transmit the data from Transparent Ready products to a user's Web browser.Transparent Ready products communicate their data using the Modbus serial link protocol, the most popular communication protocol in the industrial world.

Previously managed by Schneider Electric, Modbus is now in the public domain allowing total specification openness.The Internet IETF authority has approved the creation of a specific port (502) for devices connected to Internet/Intranet using the Ethernet Modbus TCP/IP communication protocol.This section will allow you to better understand how your enterprise Intranet system and Transparent Ready can coexist.For large industrial facilities or highly automated workshops, this section demonstrates how Transparent Ready solutions for electrical distribution applications, dedicated to people involved with electric power systems, coexist efficiently with automation systems or Scada systems.

Modbus Serial LinkDe facto industrial standard

0

Modbus is a messaging protocol between Transparent Ready devices connected to an RS 485 physical transmission bus. The industry’s serial de facto standard since 1979, Modbus continues to enable millions of automation devices to communicate. The same communication functions are provided by serial links and Ethernet TCP/IP networks.

DB

1080

96

Modbus is a request/reply protocol offering services specified by function codes.Every device connected to the Modbus network is user configured with an identification number, called the Modbus address, from 1 to 247.The EGX400 Web server simultaneously queries all devices with a message made up of the target address, the request type, the function code, the location in the device and the quantity of data, up to a maximum of 253 bytes.Only a device that is configured with the corresponding address responds to the data request.Exchanges are performed at the EGX400's initiative only: this is the way Modbus master-slave half duplex (alternating exchanges) communication works.

DB

1080

97

The function codes can cover reading or writing data. In the standard Transparent Ready range of systems for electric power distribution functions, no writing to open circuit breaker is possible.A software transmission error detection mechanism called CRC16 is used to ensure that an erroneous message will be repeated and that only the one device will answer.This query procedure followed by a response implies that the EGX400 does not simultaneously have access to all of the data available from all of the products: the server successively performs one transaction per device. This layout therefore leads to restricting the number of products connected in order to retain response times that are acceptable to the user.

Your Intranet and Transparent Ready

Your IT infrastructure handles cohabitation between software applications

Your company uses its IT infrastructure to run office applications, printing, backing up data, for the corporate IT system, accounting, purchasing, ERP, for running production installations, PLCs, MES, etc. Data cohabitation on the same communication media does not give rise to any particular problem.

Application data transits an Ethernet LAN

The communication media used around the world is generally a wired Ethernet network so that connections are available everywhere within office or industrial facilities and in production shops.Transparent Ready technology can also integrate into this Ethernet media.

On the same Ethernet LAN, Transparent Ready uses the same services as your Intranet

If your company also has an Intranet internal communication network for exchanging e-mails, for sharing the data available on Web servers, you will be using a widely used and standardised communication protocol: TCP/IP.The TCP/IP communication protocol supports Web services that are in widespread use like HTTP for accessing Web pages, SMTP, e-mail messaging, among other services.Transparent Ready also uses TCP/IP and Web services since 1996.

Example: are your PCs connected together on a data network, an Ethernet network? Then a Transparent Ready solution is possible, just connect your Prisma Plus panel to the LAN and access the electrical data from your favourites on your Internet browser.

Security

Well informed, more efficient staff members, kept safe from electrical hazards

There is no longer any need to enter electric power distribution areas. As standard, no commands can be sent to electric power devices, it is only possible to view data: this is the condition to be met to ensure that company staff get immediate and significant gains from the new system. Completely safe collaborative work becomes possible, whether for electricians, maintenance or production technicians or managers.Depending on how sensitive the data is, the IT manager will assign user access rights.

Marginal impact on LAN maintenance

The company's IT manager has the technical characteristics available for adding and supervising devices on the LAN. The very low data traffic levels, the use of technology that is not affected by viruses and the use of world-wide standards means that there is no need for any bespoke investment spending to preserve LAN performance levels or to protect against additional security problems (viruses, hackers, etc.).

Fostering responsibility in outside partners

Depending on the company's security policy, it becomes possible to get the support of the usual partners involved in the electrical field: contractors, facility managers, panelbuilders, system integrators or Schneider Electric service can all assist and analyse electrical data remotely.The EGX400 Web server can regularly send data by e-mail or Web pages can be viewed remotely using suitable techniques.

Transparent Ready from basic monitoring to enterprise system

0

Traditionally and for many years now in electrical distribution applications, monitoring and control systems have been centralised and based on Scada (supervisory, control and data acquisition) automation systems.

From centralised systems to smart equipment groups

Deciding to invest in such systems, described a in the figure below, was really reserved for high demanding installation, because either they were big power consumers, or their process was very sensitive to any lack of power quality.

Based on automation technology, such systems were very often designed, customised by a system integrator, and then delivered on-site. However the initial cost, the skills needed to correctly operate such a system, and the cost of upgrades to follow the evolutions of the network may have discouraged potential users to invest.

Then, based on a dedicated solution for electricians, the other approach described as is much better suited to the specific needs of an electrician network and really increases the payback from such a system. However, due to its centralised architecture, the entry level of such a solution may still appear high.On some site type and type systems can cohabit, providing the most accurate information to the electrician when needed.

Nowadays, the new concept of Transparent Ready power equipment, described as , has come. Taking the opportunity offered by Web technologies, it has become

a truly affordable solution for most users. Moreover the site owner can invest gradually in more sophisticated monitoring systems.

A powerful capability offered by the Transparent Ready solution is that the level system directly addresses the needs of specialised staff members, whether the user's electrical technicians or facility management or the manufacturer’s service personnel.Level can then be considered as a stepping stone for moving on to level or

, due to the ability of these solutions to co-exist at a single facility.

System

Note that level Web pages do not allow operating the control mechanisms on circuit breakers or other power equipment, as described in this catalogue.Only levels or allow control actions in line with safe software procedures developed by system integrators.Level Web pages display a selected set of electrical data available from Transparent Ready products.

Note:

all other data can be accessed using any device that runs the Modbus TCP/IP protocol (router capability) simultaneously with the ability to display Web pages (server capability).

Cohabitation between level 1 and level 3 architectures

The Transparent Ready solution truly innovates: a Scada system can operate the electrical equipment and maintenance staff can simultaneously take advantage of the measurements displayed on the EGX400 Web pages.As the Scada system detects a global alarm from the process, the operator, who is not an electrician, can ask the electrical staff to check the problem from their own dedicated power equipment Web pages.

Intelligent equipment based architecture

This new architecture has appeared recently due to Web technology capabilities,and can really be positioned as an entry point into monitoring systems.Based on Web technologies, it makes the most of standard communication services and protocols and license-free software.Access to electricity data can be gained from anywhere on site, and electrical staff can gain a lot in efficiency.Expertise in electro-technical fields is not needed, merely common sense to react to the quantities displayed by the Web system.Openness to the Internet is also offered for off-site services, e.g. contractors, facility managers, panelbuilders or Schneider Electric service.Setting up these systems is typically a speciality performed by panelbuilders used to integrating LV and MV power equipment with metering and protection devices.No system integrator skills and no software development are needed.

System

A centralised architecture dedicated to electricians

Expert electricians may use an architecture based on a specific centralised supervision system that fully matches the needs for monitoring an electrical network.In this kind of system, all electrical distribution devices are already present in the dedicated library. The purchase costs are minimised in comparison with a digital control system or a Scada system.A degree of system integration effort, although limited, is required: tuning the operating system, database management, LAN interfacing, customising displays.

Conventional general purpose centralised architecture

Here is a typical architecture based on standard automation components like Scada systems and gateways.Despite their real efficiency, these architectures suffer from some drawbacks like:

b

the level of skills required to operate them

b

poor upgradeability

b

and in the end, risky financial returns from such solutions.They are however unparalleled for highly demanding facilities and remain highly relevant for central operation rooms.Here system integrators have a major contribution to make to dedicated automation functions (real time performance levels), specific man machine interface tasks and in integrating communication systems from various manufacturers.

Complementarity between electric power distribution and industrial automation systems

Transparent Ready is the Schneider Electric solution that is common to both electric power distribution fields and industrial automation systems in order to distribute data from Ethernet TCP/IP and Web service technologies.This advanced communication solution is available in our products, for use in different areas:

b

electric power distribution:

v

simple

monitoring

of essential electric power measurements and/or

v

control

and monitoring

functions on the electric power network for facilities that, for example, require automatic network reconfiguration functions like oil refineries do

b

industrial automation systems:

real time

communications and

data sharing

without intermediaries, between the various applications that make up an industrial process and

diagnosis

on PLCs and other automation systems connected to Ethernet, such as man-machine interfaces, speed drives, etc.

DB

1081

In electric power distribution applications, the PowerLogic range of solutions fulfils specialised electric power distribution measurement functions with Circuit Monitor and Power Meter products.Numerous other specialist electric protection, motor control, UPS management systems, etc. also fulfil additional electric power network measurement functions and also add diagnosis functions for the corresponding power devices: asynchronous motors, transformers, etc.

Example: Altivar speed drives provide indications on a motor's thermal condition.

Some of them can simultaneously perform commands affecting power devices, circuit breakers, motors, at the request of the control and monitoring systems.

Example: Sepam, Micrologic, Altivar, etc.

This combination offers the prospect of useful expansion to systems at facilities where electric power distribution and consumption needs demand automatic decision making based on relevant electrical measurements.

Ethernet Modbus TCP/IPExpert level

0

This section is dedicated to information technology specialists.Any company that has a Local Area Network (LAN) for its office computing needs: shared printer, file servers or for other conventional applications like production management, purchasing management, etc., is ready to connect Transparent Ready electrical equipment.The objective is to demonstrate how Ethernet Modbus TCP/IP is now an industrial standard for medium and large, single or multiple facility installations, fully compatible with existing Intranet systems used on-site.b the industrial communication standard: Ethernet TCP/IPb Ethernet TCP/IP communication services: Modbus on TCP/IPb securityb means of access to electrical data from Intranet/Internetb other services.

The industrial communication standard: Ethernet TCP/IPThe recognition of Ethernet TCP/IP, both in organisations and on the Internet, hasmade it today's communication standard. Its widespread use is leading to a reduction in connection costs, increased performance and the addition of new functions, which all combine to ensure its durability.Ethernet TCP/IP meets the connection requirements of every application:b twisted pair copper cables for simplicity and low costb optical fiber for immunity to interference and for long distancesb communication redundancy, inherent to the IP protocolb radio or satellite systems to overcome wiring restrictionsb remote point-to-point access via the telephone network or the Internet for the cost of a local call.With its high speed, the network no longer limits application performance. Network architecture can evolve without difficulty and products remain compatible, ensuring long-term system durability.Transparent Ready solutions use Ethernet and TCP/IP in a way that is fully compatible with any other applications using the same Ethernet wiring system and TCP/IP technology, thanks to its total conformity to applicable international standards.

Example: there is no need for a dedicated Ethernet cable for Transparent Ready solutions, just use the existing Ethernet infrastructure.

Ethernet TCP/IP communication services: Modbus on TCP/IPTransparent Ready products allow communication on a single EthernetTCP/IP networkIn addition to universal Internet services (HTTP, BOOTP/DHCP, FTP, etc.), the Transparent Ready device communication services designed for use in industrial applications include, depending on the devices:b Modbus TCP messagingb SNMP (Simple Network Management Protocol) network administrationb NTP (Network Time Protocol) time synchronisationb notification of events via e-mail with SMTP.

See www.modbus-ida.com.

Modbus TCP/IP messaging: now a standard Web serviceModbus has been the de facto standard for serial link protocols in industry since1979. It is used for communications by millions of devices. As a result of this success, the IANA institute (Internet Assigned Numbers Authority) has assigned the port TCP 502 which is reserved for the Modbus protocol.Modbus and Modbus TCP are recognised by IEC 61158 international standard as a fieldbus. They are also compliant with the "Chinese National Standard" managed by ITEI. Visit the Web site at www.modbus-ida.org.Modbus can thus be used for exchanging automation data on both Ethernet TCP/IP and the Internet, as well as for all other applications (file exchanges, Web pages, e-mail, etc.).Because of the simplicity of its protocol and the high speed of 100 Mbits/s Ethernet, Modbus TCP/IP delivers excellent performance.

An identical application protocol is used for Modbus serial link or Modbus on Ethernet TCP/IP: this therefore makes it possible to route messages between both types of network without changing protocol.As Modbus is implemented above the TCP/IP layer, users can benefit from IP routing, which enables devices located anywhere in the world to communicate.Schneider Electric offers an entire range of Web servers and routers for interconnecting a Modbus TCP/IP network to an existing Modbus serial link network.When accessing product data on the Modbus serial link, using Modbus messaging, the servers and routers have no added value other than translating addresses, encapsulating and un-encapsulating Modbus frames in TCP/IP protocol, whatever function code is used (transparent data access).

Our servers and routers thus provide products on the Modbus serial link with Ethernet bandwidth and a multi-master operating capability. Up to ten TCP sockets can be simultaneously processed on EGX400 server for sharing between users with browser and control systems.One TCP socket then has to be set up to access the various Modbus devices connected to EGX400 and their registers.This latter function is also effective when the Modbus master is connected directly to one of the two Modbus serial link ports on the servers and routers (configured this way).

Example: multi-master operating capability means that the user can display the Web pages with their own browser, while another user displays the same or different Web pages from the same server and that a digital control system can access the same data from the same or different connected products on this server.

Note: a router has no embedded Web pages (see EGX100) as a Web server is not only a router but also embeds Web pages.

Modbus TCP/IP characteristicsMaximum size of data:b read: 125 words or registersb write: 100 words or registers.

EGX400 Web server mechanisms for dynamic reading via the WebNote: EGX400 uses a fixed IP address.

EGX400 uses HTML language for serving the Web pages containing dynamic values associated with the products on the Modbus serial link, and is therefore compatible with all Web browsers. This mechanism is totally transparent to users who only need their IP address or domain name.When the Web page is viewed (action , receiving an HTTP request from the Web client), the EGX400 analyses the contents of the requested Web page, detects any "<PL>" tag, then executes the Modbus services required for reading the dynamic variables (actions and ), fills in the HTML page accordingly and sends it all back as if it were a static page (action ). The HTML page is displayed on the browser screen.The page is automatically updated by the browser every five seconds.

"<PL>" tagThe dynamic data in the page uses a "<PL>" tag inserted in the code which specifies the characteristics of the Modbus service required for finding the value of this variable in the Transparent Ready products connected to the EGX400.Characteristics are Modbus function code, Modbus address, register no., LSB order, unit.

SecurityStakes and risk classificationInformation system security is intended to protect against information system related risks. These risks are dependent on a number of factors:b threats made against the devices to protectb device vulnerabilitiesb device sensitivity which is a combination of different factors: confidentiality, integrity, availability.This is why the equation is generally expressed as:Risk = Threat x Vulnerability x Sensitivity.The main effective threats that one may face comprise:b the user: the vast majority of IT security related problems are user related (through carelessness or maliciousness)b malicious programs: a program that is designed to damage or abuse system resources is installed whether by accident or maliciously on the system, opening the door to intrusion or modifying datab intrusion: persons succeed in accessing data or programs that they are not supposed to accessb accidents (theft, fire, water damage): a bad move or malicious action that leads to a loss of equipment and/or data.Generally, IT system managers have implemented security procedures and equipment.

Example: identifying persons authorised to use the IT infrastructure, firewall, DMZ, etc.

Specific security risks on Ethernet Modbus TCP/IPb Ethernet TCP/IP is a universal communication network that is familiar and accessible to a huge number of usersb the use of Ethernet TCP/IP for Transparent Ready products enables external connection without the need for any interface.

Main risks:b overflow of multiple "PING" requests with the ICMP protocol to create a denial of service to the moduleb reading/modification of Web server pages with the FTP protocolb modification of variables in Transparent Ready products by using Modbus TCP/IP protocol.

Minor risks:b virus risks are extremely limited at industrial system level, as they are based on well known widespread operating systemsb increase in traffic on Ethernet: as the Modbus TCP/IP messaging traffic is limited as regards message size and frequency (no permanent traffic, no printer traffic, only on requests from few users), this can be neglected.

These risks must be dealt with at each level:b possibility of using a router as access manager to the lower levels, by filtering the IP addresses and authorised communication protocolsb set up an internal security policy, ensuring that only authorised persons can connect to the network locally. Use the authentication, password and IP address filtering functions available at control system product level.

Example: EGX400 case. Three different types of users can access the data through dedicated passwords: the administrator, the user authorised to modify some basic settings, the read-only user.

Means of access to electrical data from Intranet/InternetIntranetThe Transparent Ready solution is primarily dedicated to use via Intranet, even if it remains possible, under certain conditions and under an access control, to gain device access over the Internet.

InternetInternet access to a Transparent Ready device must necessarily be thought by IT systems managers, depending on the security procedures applicable within their organisation.

Medium sized companyMany small or medium sized companies, located in an office or industrial building already have an Intranet for office computing, accounting or production management purposes, for example.From the moment that one or more PCs are networked, Transparent Ready electrical devices can also be connected and make their Web pages available.These companies have limited IT systems infrastructures.The facility is typically connected to Internet through a provider with a connection via an ordinary phone line or, as is more and more often the case, via an ADSL broadband line and an intelligent modem.The provider assigns the facility a fixed IP address that is therefore accessible from the outside world. To access the Transparent Ready device from Internet via the facility's intranet, as is the case for example for a duty agent at home, the modem is generally able to create one or more VPN (Virtual Private Network) connections when the staff member or service provider establishes the remote connection. This remotely accessed modem, the RAS Remote Access Server modem, makes it possible to authenticate persons wishing to access the electrical device at the time when the procedure starting the VPN is run.In addition, either a firewall is installed by the facility's IT systems manager or the provider offers a firewall, thereby securing the data flows exchanged with the Internet.The firewall on the way into the facility Intranet must be configured to allow access to the Web pages generated by the Transparent Ready devices (HTTP service).

88



DB

1081

Large company, multi-sites, multiple facilitiesDifferent solutions are possible:b the IT manager can install a VPN server for roaming staff members who wish to access a Transparent Ready device. In this case it is necessary to install a VPN client on the PC. This is the preferred solution.b using a firewall and reverse proxy application relays, it is possible to allow incoming data access to Transparent Ready devices. The staff member can, using a domain name, easily access EGX400 web pages. Incoming data flows are not however always allowed, depending on the applicable security policy.It is possible to create a DMZ if the EGX400 is not too far away geographically.

Other servicesSetting the timeThe EGX400 can have its time set by the Web NTP service which is generally supported by a server in major companies.

Sending e-mail using the EGX400It is necessary to grant the EGX400 permission to send e-mail messages, depending on the way the company's SMTP services are secured.

SNMP serviceThe EGX400 MIB is made available to the network manager using the SNMP service. Consult your local Schneider Electric correspondent for detailed information.

Baud rate

The speed at which data is transmitted over communication lines. Expressed in bits per second.

Bits

A contraction of binary digits, the smallest unit of data in binary notation. A bit takes the value of zero (0) or one (1). For example, binary number 0110 comprises four bits.

Bluetooth

Bluetooth makes cable and infrared connections superfluous and allows wireless data exchange between devices. The radio distance can be up to 10 meters.

BOOTP/DHCP (RFC1531)

BOOTP/DHCP is used to automatically provide the devices with the IP parameters. This avoids having to manage the addresses of each device individually. Management is instead performed in a dedicated IP address server.DHCP protocol (Dynamic Host Configuration Protocol) is used to automaticallyassign the devices their configuration parameters. DHCP is an extension of BOOTP.DHCP protocol is made up of two components:

b

one for providing the IP network address

b

one for providing the IP parameters specific to the device from a DHCP server.Telemecanique devices can be:

b

BOOTP clients allowing automatic recovery of an IP address from a server

b

BOOTP servers enabling a device to distribute IP addresses to the networkstations.

Domain

Corresponds to the address of the Internet, Intranet or Extranet site on the Web. To stop two individuals or corporate entities from registering the same domain name there are management organisations tasked with ensuring consistency in Internet "naming", like NIC for .fr and InterNIC for .com, .net and .org names.

Example: journaldunet.com is a domain name.

EIA (Electronic Industries Association)

A standards organisation specialising in the electrical and functional characteristics of interface equipment.

EN 50160

Standard NF EN 50160 was created to characterise the quality of the voltage supplied. This standard presents the various types of interference that can affect the voltage supply to the customer's delivery point, depending on the waveform, voltage level, frequency and unbalance in the case of a three-phase system. It therefore lists the parameters to be monitored and the duration of any monitoring.
