3 Metrology

The metrology function of the ACE SL7000meter compiles a large number of basicmeasurement quantities that are thenprocessed by the meter.

This is done in several steps through acombination of hardware and firmwarefunctions.

The ACE SL7000 meter uses uniquemetrology electronics (for CT or DC, 50 Hzor 60 Hz), and 2 types of current sensorsincluding a 1/2000 MCT (mutual currenttransformer) for whole current meters, anda 10/2000 MCT for CT meters. The outputof an MCT, being proportional to thevariations of the current, is integrated toprovide the current signal to the electronics:Voltage is provided to the electronicsthrough a resistive divider:

The three voltage signals and the threecurrent signals are transformed on the topboard by a 6-channel, 16-bit, second orderanalogue to digital converter. This is basedon the sigma-delta technology, widely usedin the audio industry. Digitised values ofcurrents and voltages samples are providedevery 0.5 ms.

Active and reactive power and energymeasurements are then calculated bymultiplying voltage and current signals (aftertransformation of current for reactive),integrating them over nearly one second,and comparing the result with a threshold,in order to deliver a number of pulses,which quantify the quantity.

At this level, the following quantities areavailable: per phase active and reactiveenergy, Irms Urms neutral current and neutral voltage displacement.

The three phase voltages (Urms) areprovided every 40ms for Voltage Qualityanalysis (for 4-wire connections). Swells,sags and cuts are detected. If their durationis longer than 80ms information about timeand duration of the event are available.

At a higher level, the metrology computesthe per phase apparent energy, using,according to the configuration, either thearithmetic method, or the vectorial method:

(true apparent power - gives good results above Ib/10)

• S = P2 + Q2 (this method is moreprecise at low currents)

Aggregate (three-phase) data are thencomputed in the application.The next levelis the computation of all angles, the phasesequence, and the power factors.

The angles calculation is done withexcellent precision, using P and Q, withthe calculation of atg (Q/P).

4 Quantities

A complete set of measurement quantitiesare available in the ACE SL7000, regardlessof the version and resource level.

Quantities are updated each second.For 3-wire systems, the phase data arecalculated by generation of a virtual 4 wiresystem with an artificial neutral point.Quantities are used for data processing bythe meter, and are also available forvisualisation on the LCD display asinstantaneous values.

Up to 4 external energy inputs(from external electricity, water, or gasmeters) are available in the flexible version.These inputs can be used for separatecounting (even multi-tariff and demand), orsummation.

Summation can be done between externalpulse inputs or between external pulseinputs and an internal channel.

5 Energy Metering

5.1 Total Energy RegisteringThis ACE SL7000 meter provides total energyregistering for all 52 energy quantities.

Total energy registers are dedicated to storethe total consumption in one register,independently of tariffs. These registers arenot reset at the end of a billing period.They can be used for single tariffapplications, whatever the resource level.

5.2 Energy RegisteringAccording to the chosen resource level, upto 10 independent energy channels can beselected from the list of 52 energyquantities.

Tariffs are applied to these channels with amaximum of 8 rate registers per channel,and an overall total number of 32 rateregisters. A unique rate is active for eachchannel at any time.

Meter configuration is totally flexible. It ispossible to have different rate configurationin different energy channels. Example:several rates for the active energy and onesingle rate for the reactive energy.

Specific registers are dedicated to store theworking time of each energy rate register(in seconds). These registers are neverreset.

The ACE SL7000 meter offers twopossible modes of accumulating energy inrate registers. Either the energy rateregisters are reset at the end of a billingperiod, or they are never reset and theenergy will continue to accumulate duringthe next billing periods.

At the end of a billing period, the energy registers are read and stored in historicalregisters.

Up to 18 historical register sets areavailable in a circular memory.

The resolution of energy quantitiesmeasurement is 100 mWh/mvarh(secondary values). Before storage (inprimary values), they are divided by aprogrammable ratio, to get a resolution of 1Wh, 1 kWh, or 1 MWh, in order to optimisethe storage range, according to the CT.VTratio. The meter can manage up to 9significant figures and 3 decimals for anenergy value.

The maximum register value is just below1000 TWh (ratio 107, unit MWh).

When a register reaches its maximum value,it is automatically reset and restarts fromzero, just as an electromechanicalcounter.

6 Demand Register

6.1 Demand Channels and TariffsAccording to the chosen resource level, up to10 independent demand channels can beselected from the list of 52 energy quantitiesthe meter can measure, plus 1 quantity whichis the aggregate power factor.

Tariffs are applied to these channels (exceptaggregate power factor) with a maximum of 8rate registers per channel, and an overall totalnumber of 24 rate registers for demands.

At any time, several rates can be active for ademand channel, and it is possible to havedifferent rate configurations in each demandchannel.

Demand registers are dedicated to store theaverage demand over a fixed time calledintegration period.

The main processes linked to thecalculation of the Demand are thefollowing:• instantaneous demand and power factor

calculation (updated each second)• average demand calculation over anintegration period

• average 3-phase power factor calculationover an integration period

• maximum demand calculation and storageof the 5 highest peaks in the billing period

• minimum power factor calculation andstorage of the lowest values in the billingperiod

• average power factor calculation andstorage in the billing period

• threshold comparison for excess demanddetection

• time stamping• net and cumulative maximum demand

memorisation.

At the end of each interval, the demandregisters are processed.

The current demand registers are thenreset to zero, to begin counting for the nextdemand.

6.2 Demand FunctionalitiesThe ACE SL7000 meter integration period isprogrammable from 1 minute to 60 minutes.

Two modes: block period or sliding period.For sliding period, a maximum of tensubintervals can be programmed.

Only one integration period mode and timecan be programmed, which is common forall demand channels.

A rising value is available for each demandchannel, and represents the currentdemand value at any given time during theintegration period.

This register is refreshed every second, aswell as the elapsed time in the integrationperiod.

Specific actions can be programmedaccording to the value of the demand, inorder to inform the customer aboutpossible excess demand:• Comparison every second of the rising

demand with a threshold• Comparison every second of the demand

extrapolation to the end of the period witha threshold; this comparison beinginhibited during the first 30% of theperiod

• Control at the end of the integrationperiod to a threshold.

Sliding period: A selected number ofsubintervals make up the demand period.

At the end of every subinterval, a newdemand calculation occurs, based on thelast full demand interval.

After the first complete sliding periodincluding 5 subintervals, when the nextsubinterval (the sixth) is reached, the newcalculation doesn’t take into account thefirst subinterval, and so on.

10

During the same billing period, the meterstores the five highest peaks of demands,with their dates and time stamps, theminimum value of the power factor, withdate and time stamps, and the averagevalue of the power factor.

Maximum demands are available ascumulative values, and net values. Thememorisation linked to the power factor is:• Minimum aggregate power factor with

time stamp• Average aggregate power factor since the

beginning of the billing period.

The end of integration period can betriggered by several ways:• by the internal clock of the meter• by a time change• after a power failure• after a change of tariff rate• by the control inputs.

In case of power failure it is possible toprogram the behaviour:• restart: a new integration period starts

after power up• resume: the period which was interrupted

by power failure continues after power upin order to keep a complete integrationperiod

• synchronise: the integration period isalways synchronised with the round hour.

The measurements obtained from anincomplete period can either be kept ordiscarded (for maximum demandcalculation and for excess demand control).The input quantities provided for demandcalculation have a resolution of 100 mWh(or mVAh or mvarh) – so the minimumresolution for a demand rate is 100 mW (ormVA or mvar) – secondary values. Beforestorage (in primary values), they are dividedby a programmable ratio to get 1 W, 1 KW,or 1 MW resolution in order to optimise thestorage range, according to the CT.VT ratio.The meter can manage up to 5 figureswhich can include 0 .. 3 decimals for ademand value. If a metering result wouldrequire a higher figure, the result is frozenat the maximum possible value.

7 Load Profiling

The ACE SL7000 meter allows up to 8independent load profile channels to beselected from the list of 52 energyquantities, plus 1 quantity for the aggregatepower factor, and plus 6 quantities for theRMS voltages and the RMS currents.

Recorded in the load profile array are dataelements, status elements, and dateelements.

Data elements are stored on 2 bytes:Each quantity allocated to a load profilechannel is integrated over a period of time(the recording interval). Then it can bestored as such, or divided by the recordinginterval (in order to calculate its averagevalue) before storage.

This recording interval can be different fromthe integration period, but is common valuefor all 8 channels. It is programmable from1 minute to 60 minutes.

Status elements are recorded over 4 bytes.

If applicable, a specific event is describedand date stamped in an additional dataelement (Clock setting, Daylight saving time,External synchronisation, power failure).

A date element (3 bytes) is inserted eachday at 00h00.

The maximum capacity for a recordinginterval of 15 minutes is 15 weeks (3 1/2months) when all 8 channels are used.

8 Power Supply

8.1 Power supply functionalitiesThe ACE SL7000 meter has a fullyredundant three-phase autoranging powersupply.The same meter works between 3 x 54 Vto 3 x 240/415 V in any of the followingfailure conditions:• missing one or two phase (4-wire

systems)• missing one phase (3-wire systems),• missing neutral or neutral and one phase

(4-wire systems)• inversion of one phase and neutral (4-wire

systems).

The meter maintains full accuracy in both4-wire and 3-wire configurations. Anindication of the supply phase condition andthe phase sequence is provided on thedisplay.

The power supply has enough reserveenergy for 3-phase power outages up to 1second.

Power failure events (per phase and total)are recorded with a duration, date and timestamp.

The meter complies with over-currentrequirements specified in IEC 60687 orIEC 61036.

In the event of continuous absence ofpower, all data are kept in a non-volatilememory, with a retention time of at least 10years without the aid of any backup power.Power consumption requirements for multi-energy and multi-function meters areaccording to the specifications in theIEC 62053 Ed.1. Without communicationand display backlight the powerconsumption does not exceed the valuesgiven by IEC 60687 or IEC 61036.The back-up power supply is designed onlyfor the real-time clock and the main coveropening detection.

The meter is equipped with a super-capand an optional lithium battery.

• Lithium battery only: minimum capacityof 3 years in continuous operation at25°C, minimum shelf-life of 10 years, withless than 10% loss of capacity due to self-discharge at 25°C.

• Super-cap only: minimum capacity of 6days power outage carry-over period after10 service years of the meter at 25°C.

• Super-cap + Lithium battery:Combination of both functionalities, duringa power failure, the super-cap is the firstto be drained.

The meter is designed in such a way thatthe Lithium battery can be safely changedwithout breaking any metrology seals andwhile the meter is operating. The operator issafe from any potential electrical hazardand is not able to touch any conductorconnected to the meter. Adequateprotection against electrostatic damage isbuilt in the meter.

8.2 Auxiliary power supplyThe meter can be optionally equipped withan auxiliary power supply, which will allowall the meter functions to continueoperation, even when the 3 phase voltagesare cut.

Voltage input: from 100VAC to 400VAC, +/- 20% , to be provided via an externaltransformer. The external transformer willprofide isolation, common mode surgeimmunity, and differential mode surgeimmunity. Alternatively the meter alsoaccepts a DC voltage from 48 to 400V.Also for this application an external isolatingDC/DC transformer needs to be fitted.

9 Time Switch /Tariff Rate Calendar

The ACE SL7000 meter’s time switchpossibilities are extremely wide and offerlarge flexibility.

The tariff structure can be described interms of patterns of tariff rates (1 to 8rates) for each channel, independent fromeach other, of daily profiles (with rateswitching at given times), of seasons(months including daily profiles for each dayof the week), and of specific or exclusiondays (fixed or moveable holidays, religiousholidays…).

The programmed information contains a latent and current time switch structure.The date of change is programmable.Tariff control is possible using the internaltime switch, or external control inputs, oreven a combination of both.

Control inputs can be used to activate arate, or a daily profile, or to activate aseason. Several control inputs can be usedfor external control of one suchfunctionality. A season change can betriggered by the DST activation.

Up to 50 different rate patterns – index –(for energies, demands, tariff outputsactivation), can be used to describe themeter’s behaviour regarding tariffication.

10 End of Billing

The ACE SL7000 meter can be configuredso that up to 5 different sources can (ifauthorised by configuration) trigger an endof billing period (MDI reset); These aresummarised in the diagram below.

In order to secure the EOB, it is possible toprogram a Lock-Out-time, which is a delaybetween two consecutive resets of MDI.

Locking interactions between categories areprogrammable.

11 Real Time Clock (RTC)

The meter internally calculates date andtime, based either on a quartz, or on mainsfrequency, according to configuration. Theresolution is one second.

The meter manages leap years, andDaylight Savings Time.

Date and time are used for controlling tariffswitching, interval measurement, and timestamping of events and results.

RTC characteristics comply with IEC 61038.

12.1 LCD Display and Push-ButtonsThe ACE SL7000 meter’s LCD Display isdedicated to provide direct access to up to100 parameters, including:• Current energy and demand registers• Billing information• Fundamental network parameters• Historical registers• General Alarm signal and status word...The list of displayable parameters is fullyprogrammable.

T on and T off are programmable for theauto-scrolling (normal list). Backlight facilityis available with all versions.

Scrolling push-button:This button is dedicated to scroll availableparameters, as specified in lists defined bythe configuration software. The meter canmanage 1, 2 or 3 lists (normal, alternateshort, and alternate long).

Reset push-button:This sealable button is just below the scrollingpush button. It is used to reset the maximumdemand indicators and close the billing period.

Laboratory switch:A switch, located inside the metrologicalenclosure, can be used to protect the meteragainst non authorised programming attempts.The association of both, scrolling and reset pushbuttons can activate the different display modes:• The normal mode which is active by

default, all available parameters are auto-scrolling with a pre-programmed time-out between them; In this mode atest of all segments of the LCD is availableby pressing the display button; If thedisplay button is kept pressed down or thebutton pressed a second time the alternatelong mode is activated; If the reset push-button is pressed during the LCDtest, the alternate short mode is activated.

• The alternate long mode: manuallydisplays alarms and parameters accordingto a specific programmable list (extendedlist, accessible to the end user).

After a time-out, or at the end of the sequence, the meter returns to the normal mode.

From this mode, it is possible to enter the set mode by pressing the reset push-button.

• Set mode: In this mode, it is possible tomodify some of the parameters, such as thedate, or the time. After a time-out, or aftervalidation, the meter returns to the alternatemode.

• The alternate short mode: manual displayof alarms and parameters, according to aspecific programmable list (extended list,accessible to the utility only); After a time-out, or at the end of the sequence,the meter returns to the normal mode.From this mode, it is also possible to enterthe set mode by pressing the resetpush-button.

For each display list, it is possible toconfigure the parameters that will bedisplayed. The sequence order is alsoprogrammable, but unique for the 3 lists.Size of the viewing area: 26mm x 90 mm. Segments height: 12 mm.

12.2 LED IndicatorsThe meter has two LED indicators tocontrol the accuracy of the meter, in alaboratory, or on site with an appropriateportable standard meter.

The two LED’s deliver flashes correspondingto the quantum of energy with a valuemarked on front of the meter. These valuesare (secondary values): DC version 1 Wh, CTversion 0.1 Wh. Ton = 10ms.

The LED can deliver independently eitherActive energy, or Reactive energy.

12.4 Optical Communication PortThe meter integrates one IEC 61107 optical

port. It is dedicated to local communication

with the meter. A sliding cover can be

sealed to protect this optical port.

The optical port uses the protocol describedby IEC 61107 for reading register data fromthe meter. It also uses the draft new versionof IEC 61107 (IEC 62056-21) to allowswitching to another protocol, calledCOSEM. This makes it possible to programor read the meter. The baud rate can beselected between 300 and 9600 bauds.

One internal serial channel is allocated tothe optical port and to the utility electricalport. By default the electrical port is active.However, when an optical portcommunication demand is detected, thechannel switches automatically to the IRoptical port.

12.5 Electrical Communication PortsElectrical ports are available to allowcommunications between the meter andthe utility (1 x RS232, or 1 x RS485) andalso eventually the end user (1 x RS232). Apower supply is available on both forpowering up an external modem (totalcapacity of 100 mA at levels from 5V to12V DC).

The 2 ports can operate independently andconcurrently.

12.5.1 Utility PortThis port is in compliance with the V24/ EIARS232D or with the RS485 standard.The port is primarily designed to operatewith an external modem, but will also allowoperation in a direct connection.The baudrate can be selected from 1200 to19200 bauds, using the COSEM protocol.

12.5.2 End User PortThis port is in compliance with the V24/EIARS232D standard. Using this port allowsthe communication with COSEM, themaximum baud rate on this port being19200 bauds.

12.5.3 Modem ManagementThe modem will be connected to a publicswitched telephone network (PSTN)normally provided by the customer.Standard PSTN, GSM or LAN (internet)modem can be used with the SL7000.The ACE SL7000 meter supports thefollowing CCITT modem standards:• V.22 (Effective transfer speed: 1200bps)• V.22bis (Effective transfer speed:

2400bps)• V.32 (Effective transfer speed: 9600bps)• V.32 bis (Effective transfer speed:

14400bps).

The auto answer mode will be the normalmode of operation. The meter can performa bi-directional communication with themodem to initialise it.

12.5.4 Logical Devices and ClientsSeveral levels of security access exist in themeter. Confidentiality and privacy of dataare managed by logical devices in themeter (which can be addressedindividually), and different clientidentifications (password protected).

The ACE SL7000 meter has three logicaldevices: the “Electricity device”, the“Management device”, and the “Endcustomer device”.

Several client types are predetermined, withdifferent authorisation to access data: • “Electricity Utility - Laboratory”• “Electricity Utility - Field”• “Electricity Utility – meter reader”• “End customer” etc.

13 Network and TamperMonitoring

The ACE SL7000 meter offers theinstantaneous value and the minimum andmaximum values of the frequency over abilling period. The instantaneous and themaximum rms values of the voltage and thecurrent for each phase over a billing periodare also available.

The following situations can be detectedand recorded in a history file:Neutral current or neutral voltagedisplacement above a threshold.

Main cover opening (option):• number of cover openings• 10 last cover openings (with time stamp,

duration).

Current reversals:• number of current reversals phase 1• number of current reversals phase 2• number of current reversals phase 3• 10 last current reversals (with time stamp,

direction, phase).

Watchdog activity:• number of watchdog events• last watchdog event with time stamps.

Calibrations history:• number of calibrations• last calibration date and time.

Configurations history:• number of configurations• last configuration (end of configuration)

time stamp.

Total power failures:• number of short power failures• number of long power failures• cumulated duration of long power failures,• duration of the longest power failures with

starting time stamp• duration of the shortest power failures

with starting time stamp• 10 last long power failures (with starting

time stamp and duration).

14 Voltage Quality

For each phase, the ACE SL7000 metercan calculate and memorise voltage sags,voltage swells, and voltage cuts:

Voltage sags per phase:• number of sags• cumulated duration of sags• duration of the longest, with time stamp• duration of the shortest, with time stamp• 10 last sags (with time stamp, duration,

magnitude, phase).

Voltage swells per phase:• number of swells• cumulated duration of swells• duration of the longest with time stamp• minimum duration with time stamp• 10 last swells (with time stamp, duration,

magnitude, phase).

Voltage cuts per phase:• number of cuts• cumulated duration of cuts• duration of the longest with time stamp• duration of the shortest with time stamp• 10 last cuts (with time stamp, duration,

magnitude, phase).

15 Display of Error CodeError codes can be displayed in the displaylist, on 2 lines: first line for non fatal errors(9 characters), and second line for fatalerrors (2 characters).

The occurrence of the following non fatalerrors is indicated:Watchdog activity, battery alarm, neutralloss, temperature, communication error,configuration incoherence, clock loss, clockincoherence, voltage cut (per phase),voltage sag (per phase), voltage swell (perphase), current reversal (per phase), noconsumption, no pulse received on pulseinputs, neutral voltage displacement, neutralcurrent, external alarm, voltage isolation(per phase), current unbalance (betweenphases).

The occurrence of the following fatal errorsis indicated:RAM error, program memory error,checksum error on a memory area, severalexternal clock incoherence.

If a fatal error occurs the meter will switchto a non-operational mode, where onlyinstantaneous values will be processed andno energy counting or demand/loadprofilecalculation will be performed. This mode isindicated by the word “stop” on the LCD.

The meter should then be removed fromthe field and tested. It will still contain allmeasuring data which had been collectedup until the fatal error occurred.

16 Order InformationTo order an ACE SL7000 meter thefollowing information is necessary:
