Figure 3.27 – USB LED Indication

3.10. Clock Synchronization Each INFORMA PMD-A device has an internal clock for maintaining the time-stamp for recorded data. This clock can be synchronized to an external GPS, internal RTC, IRIG-B, or IRIG-J. When multiple INFORMA PMD-A devices are installed at any one site, any one device (the time master) can be used to synchronize the other devices (time slaves) by using a PPS signal (Refer to Figure 4.2).

Therefore, using clock synchronization, all INFORMA PMD-A devices can be synchronized to the same time and synchronously sampled to the GPS, internal RTC, IRIG-B, or IRIG-J.

3.10.1. INFORMA PMD-A as Master

Using an External GPS PPS An external GPS antenna shall be connected to the BNC connector on the rear panel of the INFORMA PMD-A device.

The antenna cable type is RG6 with BNC terminations connected to a Trimble Bullet antenna (maximum length is 45 m without an amplifier).

Using Internal RTC INFORMA PMD-A can be configured to use its internal RTC as the time reference.

When INFORMA PMD-A uses internal RTC as a time reference for its operation, the external substation pulses of PPM or PPH correct any drift in the RTC time. Alternatively,



INFORMA PMD-A can be configured to generate an internal PPH signal by counting the 50/60 Hz line frequency signal from a configured FR Frequency reference voltage channel.

Internal PPH signal should only be used when the line frequency has a tolerance of 0.06%. This would typically be used to eliminate a long-term drift in the internal RTC time when an external time reference is not available.

If the frequency in the selected voltage channel is beyond 0.06% tolerance, the device will experience frequent “Abrupt Time Shifts”.

If the amplitude in the selected voltage channel is below 10% of nominal voltage, the device will experience frequent “Abrupt Time Shifts”.

External PPH signal is validated only if it is within ±5 minutes of an hour boundary as determined by RTC time. If the PPH signal is received beyond this ±5-minute time window, it is rejected and no actions are performed. Therefore, a user must initially set the time on the INFORMA PMD-A device to an accuracy of 5 minutes while using the external PPH. External PPM signal is validated only if it is within ±10 seconds of a minute boundary as determined by RTC time. If the PPM signal is received beyond this ±10-second time window, it is rejected and no actions are performed. Therefore, a user must initially set the time on the INFORMA PMD-A device to an accuracy of 10 seconds while using the external PPM.

INFORMA PMD-A can be configured as the time master using iQ+, as shown in the following figure. Refer to iQ+ help for additional information.

Figure 3.28 - Time Management



Using IRIG-B INFORMA PMD-A can be configured to use an external IRIG-B time source as the time reference. Connect the IRIG-B cable from the IRIG-B time source to the BNC connector.

INFORMA PMD-A IRIG-B supports the following:

1. IRIG-B 001 Modulation Type : Unmodulated, also called DC level shift.

Frequency/Resolution: No carrier

Coded expression : BCD (does not include year information), CF (includes year information).

2. IRIG-B 121 Modulation Type: Amplitude Modulated Sine Wave

Frequency/Resolution: 1000 Hz carrier

Coded expression: BCD (does not include year information), CF (includes year information).

The INFORMA PMD-A device to which the IRIG-B time source is connected will be the time master. This time master INFORMA PMD-A device may now be used to provide time synchronization to other slave INFORMA PMD-A devices, using the differential or Fiber connection for PPS synchronization.

Using IRIG-J

INFORMA PMD-A can be configured to use an external IRIG-J time source as the time reference. Connect the serial cable from the IRIG-J time source to the RS232-2 port.

INFORMA PMD-A IRIG-J supports IRIG-J-14.

IRIG-J-14 The IRIG-J-14 is a Time-of-Year format with a 1-second resolution and frame length. The IRIG-J-14 baud rate is 1200.

The INFORMA PMD-A device to which the IRIG-J time source is connected will be the time master. This time master INFORMA PMD-A device may now be used to provide time synchronization to other slave INFORMA PMD-A devices, using the differential or Fiber connection for PPS synchronization.

3.10.2. INFORMA PMD-A as Slave When INFORMA PMD-A is configured as a time slave, it receives PPS input from the time master and derives the time of the day by using NTP over the network.

INFORMA PMD-A can be configured as a time slave using iQ+, as shown in the following figure. Refer to iQ+ help for additional information.

For INFORMA PMD-A to be fully time-synchronized as a time slave, both PPS and NTP are required from the time master.



Figure 3.29 – INFORMA PMD-A Time Master/Slave Configuration

Note In the absence of PPS input for the slave mode of operation, INFORMA PMD-A will use NTP time as the time reference from the configured NTP server. Because INFORMA PMD-A is not synchronized with the PPS time marker, the accuracy of time synchronization is impacted.

3.10.3. INFORMA PMD-A Time Accuracy

Figure 3.30 - INFORMA PMD-A Time Accuracy

3.10.4. PPS Detection, Stability, and Lock Mechanism INFORMA PMD-A can be configured with any one of the external PPS sources for time reference. Once the edge of the external PPS is detected, the “ON” duration of the PPS pulse is checked, and it must exceed a minimum of 100 ms for the PPS to be validated.



The next level of validation is the “PPS stability check”. The external PPS pulse is said to be stable, as long as the PPS to PPS duration remains constant within the acceptable jitter limit as mentioned in below table. Sl. No. External Time Source (PPS) Jitter Limit (+/- ) 1 GPS 10 µs 2 INT RTC 1 ms 3 IRIG-B 1 ms 4 IRIG-J 1 ms

This check is performed continuously and the status of the PPS stability is updated every 16 seconds. If the external PPS is stable for 16 seconds, then the PPS is declared as stable; else, it is rejected. When multiple INFORMA PMD-A devices are in the locked state, ADC sampling is synchronized. INFORMA PMD-A is said to be “locked to External time source” when the internal time is synchronized with the external time source within an acceptable band of time accuracy.

INFORMA PMD-A is said to be in “Not-Locked State” if any of the following conditions occurs:

• The external PPS does not pass the stability check.

• The time difference is not within the acceptable jitter limit.

When there is a transition of INFORMA-PMD-A internal PPS from not-locked to a locked state, time correction occurs. The time correction can happen in any of the following ways:

• Gradual time correction

• Abrupt time shift

Gradual Time Correction The INFORMA-PMD-A internal time is corrected gradually if the difference is less than 0.5 seconds with respect to the external time. The maximum error correction allowed per cycle is approximately half of the intersample delay. Approximately, the time required to perform the correction for a 0.5-second error is 8.5 minutes. As a result, after the device is switched on, the clock synchronization LED might take a maximum of 8.5 minutes to turn on indicating the system is locked. Abrupt Time Shift If the difference in time is greater than 0.5 seconds, then the INFORMA-PMD-A internal time will be abruptly shifted to the external time. The abrupt shift in time is always indicated to the user.



3.11. Analog Inputs The INFORMA PMD-A 3U device supports 9 analog channels and the INFORMA PMD-A 6U device supports 9/18/27/36 analog channels.

INFORMA PMD-A has the following types of analog inputs:

• TX-AFE

• HIA-AFE

3.11.1. TX-AFE TX-AFE analog channels have the following characteristics:

• 16-bit resolution for voltage and 20-bit resolution for current

• Phase angle between channels: Accuracy ≤ 0.1°

• Channel Input Impedance of > 2.5 MΩ (at 63 V), > 2 MΩ (at 110 V), 1 MΩ (at 230 V), and > 0.1 MΩ (at 440 V)

3.11.2. HIA-AFE HIA-AFE analog channels have the following characteristics:

• 24-bit resolution for voltage/current

• Phase angle between channels: Accuracy ≤ 0.1°

• Channel input impedance of 4 MΩ Refer to Appendix A for details on the technical specifications. For TX-AFE and HIA-AFE, the range of input of the analog channels is listed in the following table: Channel Type Nominal Values Full Scale Deflection (FSD) AC Voltage 63.5 V

120 V 240 V 440 V

140 V 270 V 480 V 800 V

AC Current 1 A 2 A 5 A 10 A

10 A 20 A 50 A 100 A

DC input Voltages

12 V 120 V 240 V 480 V

Current inputs (4-20) mA current loop External current clamp



Selection of the nominal value is through jumper settings that are available internally to the TX-AFE and HIA-AFE boards. The appropriate FSD of any channel is configured at the factory as per the customer order. TX-AFE and HIA-AFE support a maximum overload of 1000 V continuous; 3.6 times of nominal voltage (maximum input voltage) for 10 seconds.

Note Wire gauge to be used for TX-AFE and HIA-AFE analog inputs: 12-22 AWG.

All analog channels are calibrated at the factory and there is no need for site calibration. When there is a combination of current and voltage channels, the user must always ensure that the selected input channel is a current channel before connecting a CT circuit.

Fast Transient Recording (optional) The fast transient recording card is optional and need to fit in the factory.

• The signals taken from the HIA-AFE channel are processed in order to detect a trigger condition (when the transients occur), and to allow the digital recording of the waveforms before and after the trigger.

• The transient voltage (up to 6 kV) is detected by the TR module with a bandwidth of 2.5 kHz to 5 MHz.

• Sampling rates (user configurable):

20 MHz

10 MHz

5 MHz

2.5 MHz

1.25 MHz

• TR analog channels have a 12-bit resolution.

3.12. Digital Inputs The INFORMA PMD-A 3U device supports 32 digital inputs and the INFORMA PMD-A 6U device supports 32/64/96/128 digital inputs. All the input channels are bi-directional.

INFORMA PMD-A supports two voltage levels configured at the factory as per the customer order as shown below.

• For nominal voltage 24 V to a maximum input of 250 V:

o Less than 12 V – No activation



o (12-17) V – Undefined

o Above 18 V – Activation

• For nominal voltage 48 V, 110 V, and 220 V, to a maximum input of 250 V:

o Less than 30 V – No activation

o (30-35) V – Undefined

o Above 35 V – Activation

The scanning rate of digital inputs is 2 kHz. The minimum pulse width of the digital inputs that can be detected and recorded is greater than 0.5 ms.

The debounce time of digital inputs ranges from 0 to 1000 ms in 1 ms steps.

The purpose of digital inputs is to monitor the state of external contacts normally associated with protection relays and circuit breakers.

< Figure 3.31 – INFORMA PMD-A Digital Inputs

Digital inputs are in groups of 8 and each group is galvonically isolated from the other group.

The digital input connections are done through terminal blocks that plug into TB10 for an INFORMA PMD-A 3U device, and TB10 and TB12 for an INFORMA PMD-A 6U device.

• Terminals 1-8 are digital inputs.

• Terminal 9 is common for digital inputs (1-8).

• Terminal 10 is earth and must be connected to the system earth.

Note Wire gauge to be used for Digital inputs: 14-26 AWG.

7.1. Calibration INFORMA PMD-A is shipped after calibration. However, if the user has changed the FSD jumper setting or the nominal frequency, then the device shall be re-calibrated as per the following procedure.

7.1.1. Calibration Procedure Calibration source details are as follows:

• Voltage source error < 0.02% of full scale

• Current source error < 0.02% of full scale

The following steps must be performed for calibration: 1. Open a Web browser and enter the following URL:

<http://Board_ip_address/mfgindex>

Board IP is the IP address configured for the device and it must be mentioned in the URL. For example: <http://192.168.36.226/mfgindex>

Default user and password (mfgindex/tabindex): Username: qualitrol Password: qualcorp_techSupport10 For changing password go to: http://<ip address of device>/tabindex_password

2. Click the Calibration tab.

Figure 7.1 – PMD-A Manufacturing Utility Homepage

Maintenance


3. Identify the analog channel types (voltage/current) that physically exist on the acquisition

board. Select the channel types based on the jumper/tap settings of analog channels and group similar channel types. Once the grouping is done, click Calibrate System.

Consider the following example:

The acquisition unit has 3 current and 3 voltage channels in the following manner:

• Channels 1, 4, and 7 are current channels with tap settings 10 A and

• Channels 2, 3, and 5 are voltage channels with tap settings 140 V

In this situation, perform the following during calibration:

• For channels 1, 4, and 7, select Type as Current 10 AC and Group as 1. This indicates that Group 1 corresponds to a set of channels of type Current 10 AC.

• For channels 2, 3, and 5, select Type as Voltage 140 AC and Group as 2. This indicates that Group 2 corresponds to a set of channels of type Voltage 140 AC.

Figure 7.2 – Calibrating the System

Maintenance


4. Select the group that needs to be calibrated, and then click Continue. The device

performs offset calibration.

Figure 7.3 – Offset Calibration

Maintenance


5. The following Web page allows the user to short the input channels under calibration.

After shorting all the channels displayed, click Continue to proceed further. When calibrating with Relay Test Set, apply Zero current/voltage to channels under calibration.

Figure 7.4 Shorting the Channels

Maintenance


6. The calibration command is sent to the device after a delay of 10 seconds. The delay is introduced by the GUI to allow the device to settle with the specified input. During offset calibration, the device enters the Calibration mode in which all sensors are disabled, and the data recording is paused.

Figure 7.5 – Calibration in Progress

7. After the offset calibration is done, the system prompts the user for confirmation to perform a low gain calibration.

Figure 7.6 – System Prompt

TX-AFE: • For Voltage/mA loop/DC calibration, the device proceeds for only low gain calibration

• For Current/External Clamp CT, the device proceeds for low gain as well as high gain calibration.

HIA-AFE: • In HIA-AFE, all channels have only one gain calibration.

Maintenance


Figure 7.7 - Voltage Calibration

Maintenance


Figure 7.8 Current Low Calibration

8. Click Continue to allow the device to perform low gain calibration. The utility sends the command to the device after a 10 second delay.

For normal TX-AFE current calibration, the device performs a high gain calibration. The same process is followed as mentioned earlier for the high gain factor of the channels under calibration.

Maintenance


Figure 7.9 – High Gain Calibration

7.1.2. Points to Remember • The voltage/current source channels must be connected properly.

• To ensure if the calibration is done properly, the user has to form a DFR and check whether the values are proper with respect to the applied values to the device.

• If the user changes the frequency of the device in the calibration window, then the device needs to be calibrated.

• In case of an inaccurate calibration, the user has to load the default calibration values.

Figure 7.10 – Load Defaults

Maintenance


• For every group change or type change, the earlier calibration values are lost. Consider the following example:

Suppose the user has calibrated a few channels leaving all the others to “Undefined Channels”. As a result, the next time the user configures and calibrates these channels, the earlier calibrated values will be lost. In this condition, the user has to save the earlier calibrated values and then proceed.

• The default frequency setting of the INFORMA PMD-A device is 50 Hz. If the user wants to operate the device at 60 Hz, the device must be re-calibrated with a 60 Hz frequency setting. The operating frequency can be changed by using the “System frequency” drop-down menu as shown in Figure 6.2. When a frequency change occurs, the device is restarted; the user must wait for the device to restart and then proceed for calibration.

7.2. General Maintenance

7.2.3. Routine Maintenance This instrument is a solid-state electronic device and there are no adjustable or renewable parts inside that require routine maintenance.

However, after the first commissioning, it is recommended that a calibration check be performed every 5 years.

Maintenance


7.2.4. UPS Maintenance Precautions for Handling and Use of Battery:

• Avoid shorting the battery.

• Do not immerse in water.

• Do not disassemble or deform the battery.

• Do not expose to, or dispose the battery in fire.

• Store the battery in a cool, dry, and well-ventilated area.

• Never use a battery that has suffered abuse.

Acute Health Effects and First Aid Measures: In the unlikely event of an accidental exposure to the battery fluids, direct contact with skin and eyes are to be considered serious and must be treated immediately.

In the event of a contact with the battery fluids, rinse with large volumes of water for at least 15 minutes, and consult a doctor. Storage of Battery for a Long Time: If the batteries are stored for more than 3 months without use, then they have to be discharged completely and recharged until 50% of the "end of charge" voltage. If these batteries are stored for more than 6 months, there can be a serious effect on the battery life.

Appendix B – INFORMA PMD-A Functions


Appendix B INFORMA PMD-A Functions




Power Quality Parameters Power quality parameters can be distinguished between steady state phenomena and non-steady state phenomena.

Steady State Phenomena

In these phenomena, INFORMA PMD-A records PQ parameters continuously at 10-minute intervals and/or a user-defined time interval.

Steady state phenomena = continuous recording (10-minute recording and or user-defined time interval)

• Power frequency (10-second)

• Magnitude of supply voltage

• Flicker

• Voltage unbalance

• Harmonics

• Inter-harmonics

• Mains signaling (3-second)

• Over deviation and under deviation

Non-Steady State Phenomena

In these phenomena, INFORMA PMD-A records PQ events/Triggered recordings (DSI, RVC).

Non-steady state phenomena = triggered recordings/PQ Events

• Voltage dips/sags, swells, and interruptions (DSI)

• Rapid voltage changes (RVC)

Power Line Frequency (10-second) The power frequency is recorded by measuring the time between two positive zero crossings of the signal.

10-second frequency is a single value derived from configured reference channel, with time tag, and flagging information. The frequency calculation complies with IEC 61000-4-30.



Figure B.1 – 10-Second Frequency Record

Note • Applied Frequency = 50 Hz

• Measured Frequency = 50 Hz

Magnitude of Supply Voltage The RMS value of the voltage at a given time at the supply terminals, measured over a given interval. The supply voltage recording is at 10-minute intervals and/or user-defined time intervals.



Figure B.2 - Magnitude of Supply Voltage Record

Note The device is connected to the main supply. The voltage fluctuates between 235 V to 250 V.

Flicker Flicker is a slow cyclical variation of the amplitude of the RMS voltage envelope. It is the impression of unsteadiness of visual sensation induced by a light stimulus whose luminance or spectral distribution fluctuates with time.

Flicker recording complies with the IEC 61000-4-15 standard. Flicker is calculated on all three phases. Flicker data is stored in the recorder memory where it can be retrieved using the iQ+ Master Station software.



Figure B.3 – Flicker Record

Note • Flicker applied to the device is 10 Pst (nominal voltage 230 VAC).

• The green line indicates the voltage RMS value and the other 3 lines indicate the flicker Pst values on all the three phases.

Voltage Unbalance Voltage unbalance is a condition in which the RMS values of the phase voltages or the phase angles between consecutive phases are not equal.

The level of unbalance is typically monitored from 10-minute average intervals and is expressed in %.

Unbalance recording complies with the IEC 61000-4-30 standard. The INFORMA PMD-A device records the unbalance at 10-minute intervals and/or user-defined time intervals. Unbalance data can be stored in the recorder memory where it can be retrieved using the iQ+ Master Station software.



Figure B.4 – Unbalance Record

Voltage unbalance is displayed as 100% because all phases are In-phase.

Note The maximum voltage unbalance displayed is 100%.

Harmonics Harmonics are systematic distortions of the waveform resulting from the super imposition of secondary signals having frequencies of a multiple of the fundamental frequency.

The power quality recording function in the INFORMA PMD-A provides a comprehensive harmonic recording function comply with IEC 61000-4-7. The user can select up to the 50th harmonic quantity for each three-phase group of analog channels to be recorded at 10-minute intervals and/or user-defined time intervals.

The conditions in which the harmonics, inter-harmonics, and THD parameters are forced to zero are:

• When applied voltage (fundamental) is zero.

• When applied voltage (fundamental) is less than 10% of nominal voltage.



Figure B.5 – Harmonics Record

Note • Harmonics applied to the device is 6% of nominal voltage 230 VAC.

• The green line indicates the voltage RMS value and the other 3 lines indicate the voltage harmonic (% of fundamental) values on all the three phases.

Inter-Harmonics Harmonics that have frequencies equal to non-integer multiples of the fundamental are inter-harmonics.

The inter-harmonic recording function complies with IEC 61000-4-7. The user can select up to the 49th inter-harmonic quantity for each three-phase group of analog channels to be recorded at 10-minute intervals and/or user-defined time intervals.



Figure B.6 - Inter-Harmonics Record

Note • Voltage inter-harmonics applied to the device is 10% and then 5% of nominal voltage 230V AC.

• The green line indicates the voltage RMS value and the blue line indicates the voltage inter-harmonic (% of fundamental) value on a single phase.

• The user can observe a slight variation in the voltage RMS because of the delay in the transition of voltage inter-harmonics from 10% to 5% of nominal voltage.

Mains Signaling Voltage Voltage signals whose frequencies are different from the fundamental frequency are injected into the network. These injected voltage signals have to remain within acceptable limits (maximum RMS value) to avoid disturbing the connected equipments.

Signaling voltage records are of fixed length (no re-triggering during a recording) and composed of 10-second pre fault and up to a maximum of 120-second post fault, specified by the user in 10-second steps.



Figure B.7 - Signaling Voltage Record

Note • Mains signaling voltage applied to the device is 5% of nominal voltage 230 VAC.

• The green line indicates the voltage RMS value and the other 3 lines indicate the signaling voltage values on all the three phases.

Dips, Swells, And Interruptions (DSI) The power quality recording is equipped with a software power quality sensor that automatically detects voltage dips, swells, and interruptions. The duration and magnitude of each incident is characterized in compliance with IEC 61000-4-30. Incidents are retained in memory and can be retrieved for display and analysis by the iQ+ Master Station software.



Figure B.8 – RMS Envelope Swell

Rapid Voltage Change (RVC) A rapid voltage change is a quick transition in the RMS voltage between two steady-state conditions.

To measure rapid voltage changes, thresholds are defined for each of the following:

• The minimum rate of change

• The minimum duration of the steady-state conditions

• The minimum difference in voltage between the two steady-state conditions

• The steadiness of the steady-state conditions

The voltage during a rapid voltage change must not exceed the DSI threshold; else, it is considered as a DSI.

Sensors are programmed to look for various types of PQ thresholds on calculated quantities and digital input changes, if they are configured as PQ sensors.

INFORMA PMD-A sensors are completely adjustable either on site, or remotely, to meet user requirements. Prefault, postfault, and Oplimit (operational limit time) logic are fully adjustable. The user can also inhibit the sensors using software and digital input configuration.

Oplimit is the maximum time for which DFR is performed after a fault occurs, if the fault persists for more than the postfault time. This comes into picture if the event trigger (causing a record to start) lasts beyond the user-specified operational limit.

The device may be configured in order to perform one or more functions.

Sensor Inhibit Using Software Configuration: Each PQ sensor can be individually enabled/disabled by user configurations.

Sensor Inhibit Using Digital Input Configuration: Each PQ sensor can be inhibited by the state of single specified digital input.

A total of 80 PQ sensors are available in INFORMA PMD-A.

INFORMA PMD-A provides the following PQ sensor types on which different types of sensors can be configured.

PQ Sensor Types Over: Applied on 200 ms data, 10-second frequency, and 10-minute flicker. If the computed value of the configured parameters exceeds the “Over_Start -threshold calculated” value, then the event is triggered. If the computed value of the configured parameter reduces below the “Over_Stop -threshold calculated” value later, then the event is de-triggered. Corresponding logs and records are generated.

Under: Applied on 200 ms data, 10-second frequency, and 10-minute flicker. If the computed value of the configured parameters reduces below the “Under_Start -threshold calculated” value, then the event is triggered. If the computed value of the configured



parameter exceeds the “Under_Stop -threshold calculated” value later, then the event is de-triggered. Corresponding logs and records are generated.

Both: Applied on 200 ms data, 10-second frequency, and 10-minute flicker. If the computed value of the configured parameters reduces below the “Under_Start -threshold calculated” value OR exceeds the “Over_Start -threshold calculated” value, then the event is triggered. If the computed value of the configured parameter exceeds the “Under_Stop -threshold calculated” value OR reduces below the “Over_Stop -threshold calculated” value later, then the event is de-triggered. Retriggering happens if the parameter value swings between Under to Over and vice-versa. Corresponding logs and records are generated.

UA-Under: Applied on Urms (1/2) data. If the Urms (1/2) value reduces below the “UA_Under Start threshold calculated” value, then the event is triggered. If the RMS value exceeds the “UA_Under Stop -threshold calculated” value later, then the event is de-triggered. Corresponding logs and records are generated.

UA-Over: Applied on Urms (1/2) data. If the Urms (1/2) value exceeds the “UA_Over Start threshold calculated” value, then the event is triggered. If the RMS value reduces below the “UA_Over Stop -threshold calculated” value later, then the event is de-triggered. Corresponding logs and records are generated.

UA-Both: Applied on Urms (1/2) data. If the Urms (1/2) value exceeds the “UA_Over Start threshold calculated” value OR reduces below the “UA_Under Start threshold calculated” value, then the event is triggered. If the RMS value reduces below the “UA_Over Stop -threshold calculated” value OR exceeds the “UA_Under Stop -threshold calculated” value later, then the event is de-triggered. Retriggering happens if the parameter value swings between Under to Over and vice-versa. Corresponding logs and records are generated.

DSI: Applied on Urms (1/2) data. If the Urms (1/2) value exceeds the “Start limits” of either Dip or Swell or Interruption, then the event is triggered. It is retriggered if the RMS value swings between any of the three limits. De-triggering happens if the RMS value is in normal limits. Corresponding logs and records are generated.

RVC: Applied on Urms (1/2) data. If the rate of change of the Urms (1/2) value exceeds the limit decided by threshold, a sensor is triggered. It remains de-triggered in normal conditions. Corresponding logs and records are generated.

Only sensors of the DSI or RVC types can initiate an RMS Envelope Recording.

These are special function sensors and may be applied to voltage channels only.

For each busbar, any of the following are allowed:

• A maximum of 3 sensors of the DSI type

• A maximum of 3 sensors of the RVC type

If the "Connection/Cable-type" is set to Aron, only two voltage channels are available; consequently 2 sensors each, of the DSI and RVC types, are available for each of the busbar.



Note that the sensors of the UA-Under, UA-Over, and UA-Both types will not trigger an RMS Envelope, although these sensors use an algorithm identical to that of DSI.

Handling Time Changes When the user is setting the device time, it can be shifted forward or backward from the current set time using the iQ+ software.

Forward Time Shift If the user has set the device time ahead of the current device time, then the situation is referred to as a “Forward time shift”.

• Forward time shift of less than 10 minutes: o The 10-second frequency counts will decrease in the EN 50160 reports (standard

threshold and user threshold) equivalent to the amount of drift.

o In a 10-minute permanent recording, the timestamps and frequency values in the drift duration are set to zero.

o In free interval recording, if the aggregation duration is configured for less than or equal to 10 minutes, then the new segment is formed. If the aggregation duration is configured for more than 10 minutes, the data corresponding to the duration of drift will not be available.

o In the IEC 61000 report, data will not be available for the duration of the drift.

o In free interval histogram, if there is no impact for all other reports when the aggregation duration is configured for less than or equal to 10 minutes, then the new report is formed from the newly set time. If the aggregation duration is configured for more than 10 minutes, then the data is not available for the duration of the drift.

o There is no impact on a 10-minute Histogram. • Forward time shift of more than 10 minutes: o A new segment is formed in both 10-minute permanent recording and free interval

recording.

o All other reports (EN 50160 standard threshold, EN 50160 user threshold, IEC 61000, 10-minute histogram, and free interval histogram) will be restarted from the newly set time.

Backward Time Shift • Backward time shift of less than 1 minute: o In free interval recording, if the aggregation duration is configured for less than or

equal to 1 minute, then a new segment is formed. If the aggregation duration is configured for more than 1 minute, then there is no impact.



o No impact on 10-minute permanent recording and all other reports.

• Backward time shift of more than 1 minute and less than 10 minutes: o No impact on 10-minute permanent recording and all other reports except for free

interval histogram.

o In free interval recording, if the aggregation duration is configured for less than 10 minutes, the recording will be restarted with a new segment once the device time reaches the current recording time. If the aggregation duration is more than 10 minutes, then free interval recording will discard the data until the device time reaches the current recording time and will not break segments.

o Free interval histogram report will be restarted at the next 10-minute boundary; till then, all recorded data will be discarded.

• Backward time shift of more than 10 minutes: The device will not record data until the device time reaches the current recording time. PQ recording will restart with the new segment once the device time reaches the current recording time. For example, suppose the current device time is 11:30 and the user has changed the time back to 9:30. The device will not record data until the device time is 11:30; this helps the user not to lose recorded data from the device accidentally because of the changed time. However, if the user wishes to start recording the data with the backward shifted time (9:30 in this case), then the following steps need to be performed:

1. Save all available data from the device to the iQ+ server. 2. Access the Causeway Web server software by entering the following URL:

<http://192.168.35.242/cgi-bin/delrecs.cgi>

Note 192.168.35.242 is the device IP address.

The following Web page is displayed.



Figure B.10 – Deleting Records

Note The user may be prompted for a password to access this Web page.

3. Select all records by clicking on the individual check boxes and then click the

Delete selected data from system button.

Now the device will start recording the data with immediate effect.

Types of Fault Recording

DFR DFR provides high speed monitoring and recording of the power system and equipment. The recording is carried out when a system fault occurs, which is user configurable. The following types of sources can initiate a DFR recording:

• FR sensors

• PQ Sensors

• External Triggers

• Digital Inputs

Figure B.11 – Digital Fault Record 1

Note For more information about capturing DFR records, refer to iQ+ Help.



Figure B.12 - Digital Fault Record 1

DFR Sensor Types Sensor Inhibit Using Software Configuration: Each FR sensor can be individually enabled/disabled by user configuration.

Sensor Inhibit Using Digital Input Configuration: Each FR sensor can be inhibited by the state of a single specified digital input.

A total of 32 FR sensors are available in INFORMA PMD-A.

Over: Applied on all FR parameters. If the computed value of the configured parameters exceeds the “Over_Start -threshold calculated” value, then the event is triggered. If the computed value of that configured parameter reduces below the “Over_Stop -threshold calculated” value later, then the event is de-triggered. Corresponding logs and records are generated. Under: Applied on all FR parameters. If the computed value of the configured parameters reduces below the “Under_Start -threshold calculated” value, then the event is triggered. If the computed value of that configured parameter exceeds the “Under_Stop -threshold calculated” value later, then the event is de-triggered. Corresponding logs and records are generated.

Both: Applied on all FR parameters. If the computed value of the configured parameters reduces below the “Under_Start -threshold calculated” values, OR exceeds the “Over_Start -threshold calculated” value, then the event is triggered. If the computed value of that configured parameter exceeds the “Under_Stop -threshold calculated” value, OR reduces below the “Over_Stop -threshold calculated” value later, then the event is de-triggered. Retriggering happens if the parameter value swings between Under to Over and vice-versa. Corresponding logs and records are generated.

Power Swing: Applied on frequency and power values. The event is triggered when it detects poorly dampened oscillations. It is de-triggered if normal condition resumes. Dx/dt: Applied on RMS values of voltage and current, frequency, and power values. The event is triggered when it detects magnitude variations. It is de-triggered if normal condition resumes.
