2. Application Notes

2.1 Overvol tage and Undervoltage Protection

2.1.1 Phase Overvoltage Protection

GRE130 provides three independent phase overvoltage elements with programmabledropoff/pickup(DO/PU) ratio. OV1 and OV2 are programmable for inverse time (IDMT) ordefinite time (DT) operation. OV3 has definite time characteristic only.

Figure 2.1.1 shows the characteristic of overvoltage elements.

Figure 2.1.1 Characteristic of Overvoltage Elements

The overvoltage protection element OV1 and OV2 have the IDMT characteristic defined byequation (1) following the form described in IEC 60255-127:

( )

1a

k t G TMS c

V Vs

(1)

where:

t = operating time for constant voltage V (seconds),

V = energising voltage (V),

Vs = overvoltage setting (V),

TMS = time multiplier setting.

k, a, c = constants defining curve.

The IDMT characteristic is illustrated in Figure 2.1.2. In addition to the IDMT curve in Figure2.1.2, a user configurable curve is available via scheme switches [OV1EN] and [OV2EN]. Ifrequired, set the scheme switch [OVEN] to “C” and set the curve defining constants k, a, c. Thesecurves are defined in Table 2.1.1.

Figure 2.1.2 IDMT Characteristic

The OV3 element is used for definite time overvoltage protection.

Definite time reset

The definite time resetting characteristic is applied to the OV1 and OV2 elements when theinverse time delay is used.

If definite time resetting is selected, and the delay period is set to instantaneous, then nointentional delay is added. As soon as the energising voltage falls below the reset threshold, theelement returns to its reset condition.

If the delay period is set to some value in seconds, then an intentional delay is added to the reset period. If the energising voltage exceeds the setting for a transient period without causing tripping,then resetting is delayed for a user-definable period. When the energising voltage falls below thereset threshold, the integral state (the point towards operation that it has travelled) of the timingfunction (IDMT) is held for that period.

This does not apply following a trip operation, in which case resetting is always instantaneous.

Both OV1 and OV2 have a programmable drop off/pickup(DO/PU) ratio.

Scheme Logic

Figures 2.1.3 to 2.1.5show the scheme logic of the overvoltage protection OV1 to OV3.

The OV1 protection allows the user to select either a definite time or an inverse time characteristicas shown in Figure 2.1.3. The definite time protection is enabled by setting [OV1EN] to “DT”, andtrip signal OV1 TRIP is given through the delayed pick-up timer TOV1. The inverse time

protection is enabled by setting [OV1EN] to “IDMT”, and trip signal OV1 TRIP is given.

The OV2 protection also provides selective definite time or inverse time characteristic as shown in

6 F 2 T 0 1 7 6

Figure 2.1.4. The scheme logic of OV2 is the same as that of the OV1.

Figure 2.1.5 and Figure 2.1.5 show the scheme logic of the definite time overvoltage protectionOV3. The OV3 gives alarm signals OV3_ALARM through the delayed pick-up timers TOV3.

The OV1 to OV3 protection can be disabled by the scheme switches [OV1EN] to [OV3EN].

2.1.2 Phase Undervoltage Protection

GRE130 provides three independent phase undervoltage elements. UV1 and UV2 are programmable for inverse time (IDMT) or definite time (DT) operation. UV3 has definite timecharacteristic only.

Figure 2.1.7 shows the characteristic of the undervoltage elements.

The undervoltage protection element UV1 has an IDMT characteristic defined by equation (2)following the form described in IEC 60255-127:

( )

V Vs

(2)

where:

t = operating time for constant voltage V (seconds),

V = energising voltage (V),

Vs = undervoltage setting (V),



The IDMT characteristic is illustrated in Figure 2.1.8. In addition to the IDMT curve in Figure2.1.8, a user configurable curve is available via scheme switches [UV1EN] and [UV2EN]. Ifrequired, set the scheme switch [UVEN] to “C” and set the curve defining constants k, a, c. Thesecurves are defined in Table 2.1.1.

The UV3 element is used for definite time overvoltage protection.

Definite time reset

The definite time resetting characteristic is applied to the UV1 and UV2 elements when theinverse time delay is used.

If definite time resetting is selected, and the delay period is set to instantaneous, then nointentional delay is added. As soon as the energising voltage rises above the reset threshold, theelement returns to its reset condition.

If the delay period is set to some value in seconds, then an intentional delay is added to the reset period. If the energising voltage is below the undervoltage setting for a transient period withoutcausing tripping, then resetting is delayed for a user-definable period. When the energising

voltage rises above the reset threshold, the integral state (the point towards operation that it hastravelled) of the timing function (IDMT) is held for that period.

This does not apply following a trip operation, in which case resetting is always instantaneous.

Scheme Logic

Figures 2.1.9 to 2.1.11 show the scheme logic of the undervoltage protection UV1 to UV3.

The UV1 protection provides a selective definite time or inverse time characteristic as shown inFigure 2.1.8. The definite time protection is enabled by setting [UV1EN] to “DT”, and trip signalUV1_TRIP is given through the delayed pick-up timer TUV1. The inverse time protection isenabled by setting [UV1EN] to “IDMT”, and trip signal UV1_TRIP is given.

The UV2 protection also provides a selective definite time or inverse time characteristic as shownin Figure 2.1.10. The scheme logic of UV2 is the same as that of the UV1.

Figure 2.1.11 shows the scheme logic of the definite time undervoltage protection UV3. The UV3gives alarm signal UV3_ALARM through the delayed pick-up timers TUV3.

The UV1 to UV3 protection can be disabled by the scheme switches [UV1EN] to [UV3EN].

In addition, there is a user programmable voltage threshold VBLK. If all measured phase voltagesdrop below this setting, then both UV1 to UV3 are prevented from operating. This function can be blocked by the scheme switch [VBLKEN]. The [VBLKEN] should be set to “OFF” (not used)when the UV elements are used as fault detectors, and set to “ON” (used) when used for loadshedding.

Note: The VBLK must be set lower than any other UV setting values.

2.1.3 Zero Phase Sequence Overvoltage Protection

The zero phase sequence overvoltage protection (ZPS) is applied to earth fault detection onunearthed, resistance-earthed system or on ac generators.

The low voltage settings which may be applied make the ZPS element susceptible to any 3rd harmonic component which may be superimposed on the input signal. Therefore, a 3 rd harmonicfilter is provided to suppress such superimposed components.

For earth fault detection, the following two methods are in general use.

Measuring the zero sequence voltage produced by a VT residual connection (broken-deltaconnection) as shown in Figure 2.1.13.

Measuring the residual voltage across an earthing transformer as shown in Figure 2.114.

2.1.4 Negative Phase Sequence Overvoltage Protection

The negative phase sequence overvoltage protection (NPS) is used to detect voltage unbalanceconditions such as reverse-phase rotation, unbalanced voltage supply etc.

The NPS protection is applied to protect three-phase motors from the damage which may be

caused by the voltage unbalance. Unbalanced voltage supply to motors due to a phase loss canlead to increases in the negative sequence voltage.

The NPS protection is also applied to prevent the starting of the motor in the wrong direction, ifthe phase sequence is reversed.

Two independent elements NPS1 and NPS2 are provided. The elements are programmable fordefinite time delayed or inverse time delayed (IDMT) operation.

The inverse time characteristic is defined by equation (4) following the form described in IEC60255-127.

The IDMT characteristic is illustrated in Figure 2.1.18. In addition to the IDMT curve in Figure2.1.18, a user configurable curve is available via scheme switches [NPS1EN] and [NPS2EN]. Ifrequired, set the scheme switch [NPSEN] to “C” and set the curve defining constants k, a, c.These curves are defined in Table 2.1.1.

2.2 Frequency Protection

For a four-stage frequency protection, GRE130 incorporates dedicated frequency measuringelements and scheme logic for each stage. Each stage is programmable for underfrequency,overfrequency or frequency rate-of-change protection.

Underfrequency protection is provided to maintain the balance between the power generationcapability and the loads. It is also used to maintain the frequency within the normal range by loadshedding.

Overfrequency protection is typically applied to protect synchronous machines from possible damagedue to overfrequency conditions.

Frequency rate-of-change protection is applied to ensure that load shedding occurs very quicklywhen the frequency change is very rapid.

A-phase to B-phase voltage is used to detect frequency.

2.2.1 Frequency element

Underfrequency element UF operates when the power system frequency falls under the settingvalue.

Overfrequency element OF operates when the power system frequency rises over the settingvalue.

These elements measure the frequency and check for underfrequency or overfrequency every 5ms. They operate when the underfrequency or overfrequency condition is detected 16 consecutivetimes.

The outputs of both the UF and OF elements is invalidated by undervoltage block element(FRQBLK) operation during an undervoltage condition.

Figure 2.2.1 shows the characteristics of the UF and OF elements.

Figure 2.2.1 Underfrequency and Overfrequency Elements

2.2.2 Frequency rate-of-change element

The frequency rate-of-change element calculates the gradient of frequency change (df/dt).GRE130 provides two rate-of-change elements, a frequency decay rate element (D) and afrequency rise rate element (R). These elements measure the change in frequency (Δf) over a timeinterval (Δt=100ms), as shown Figure 2.2.2 and calculate the Δf/Δt every 5 ms. They operatewhen the frequency change exceeds the setting value 50 consecutive times.

The output of both the D and R elements is invalidated by undervoltage block element(FRQBLK) operation during undervoltage condition.

2.3 Trip and Alarm Signal Output

GRE130 provides various trip and alarm signal outputs such as three-phase and single-phase tripand alarm for each protection. Figure 2.4.1 shows the trip and alarm signals grouped for each protection.

GRE130 provides 8 auxiliary relays for binary outputs as described in Section 3.2.3.

After the trip signal has disappeared, following the clearance of the fault, the reset time of thetripping output relay can be programmed. The setting is respective for each output relay.

When the relay is latched, it can be reset with the RESET key on the relay front panel or via a binary input. This resetting resets all of the output relays collectively.

For the tripping output relay, a check must be made to ensure that the tripping circuit is open bymonitoring the status of a circuit breaker auxiliary contact prior to the tripping output relayresetting, in order to prevent the tripping output relay from directly interrupting the circuit breakertripping coil current.

3.1 Hardware Description

3.1.1 Outline of Hardware Modules

The case outline of GRE130 is shown in Appendix E.

As shown in Figure 3.1.1, the human machine interface (HMI) panel has a liquid crystal display(LCD), light emitting diodes (LED), operation keys and a USB type-B connector on the front panel.

The LCD consists of 16 columns by 8 rows (128x64dots) with a back-light and displays recording,status and setting data.

There are a total of 14 LED indicators and their signal labels and LED colors are defined asfollows:

Label Color Remarks

IN SERVICE Green Lit when the relay is in service and flashing when the relay is in “Test”

menu.

TRIP Red Lit when a trip command is issued.

ALARM Yellow Lit when relay alarm is detected.

Relay Fail Red Lit when a relay failure is detected.

LED1 to LED6 are user-configurable. Each is driven via a logic gate which can be programmedfor OR gate or AND gate operation. Further, each LED has a programmable reset characteristic,settable for instantaneous drop-off, or for latched operation. A configurable LED can be programmed to indicate the OR combination of a maximum of 4 elements, and the LED color can

be changed to one of three colors- (Red / Green / Yellow) , the individual status of which can beviewed on the LCD screen as “Virtual LEDs.” For the setting, see Section 4.2.6.10. For theoperation, see Section 4.2.1.



30

6 F 2 T 0 1 7 6

The TRIP LED and an operated LED if latching operation is selected, must be reset by the user,

either by pressing the RESET key, by energising a binary input which has been programmed for

‘Remote Reset’ operation, or by a communications command. Other LEDs operate as long as a

signal is present. The RESET key is ineffective for these LEDs. Further, the TRIP LED is

controlled with the scheme switch [AOLED] whether it is lit or not by the output of an alarm

element such as OV4 ALARM, UV4 ALARM, etc..

The CB CLOSED and CB OPEN LEDs indicate CB condition. The CB CLOSED LED color can be changed to one of three colors-(Red / Green / Yellow) .

The LOCAL / REMOTE LED indicates the CB control hierarchy. When the LOCAL LED is lit,the CB can be controlled using the ○ and ｜ keys on the front panel. When the REMOTE LEDis lit, the CB can be controlled using a binary input signal or via relay communications. Whenneither of these LEDs are lit , the CB control function is disabled.

The ▼ key starts the Digest screen (Metering, Virtual LED) view on the LCD. The ▼ key will

scroll the screen through “Virtual LED” → “Metering” →”Indication and back-light off” when

the LCD is in the Digest screen mode.The ENTER key starts the Main menu indication on the LCD.

The END key clears the LCD indication and turns the LCD back-light off when the LCD is in

the “MAIN MENU”.

The operation keys are used to display the records, status and setting data on the LCD, to inputsettings or to change settings.

The USB connector is a B-type connector. This connector is used for connection with a local personal computer.

3.2.2 Binary Input Signals

The GRE130 provides 2 (Model 410) or 6 (Model 411) programmable binary input circuits. Each

binary input circuit is programmable, and provided with the function of Logic level inversion,detection threshold voltage change and function selection.

Logic level inversion and detection threshold voltage change

The binary input circuit of the GRE130 is provided with a logic level inversion function, a pick-upand drop-off delay timer function and a detection threshold voltage change as shown in Figure3.2.1. Each input circuit has a binary switch BISNS which can be used to select either normal orinverted operation. This allows the inputs to be driven either by normally open or normally closedcontacts. Where the driving contact meets the contact conditions then the BISNS can be set to“Norm” (normal). If not, then “Inv” (inverted) should be selected. The pick-up and drop-off delaytimes can be set 0.0 to 300.00s respectively.

The binary input detection nominal voltage is programmable by the user, and the setting rangevaries depending on the rated DC power supply voltage. In the case that a 110V / 220Vdc ratedmodel is ordered, the input detection nominal voltage can be set to 48V, 110V or 220V for BI1 andBI2, and to 110V or 220V for BI3-BI6. In the case of a 24 / 48Vdc model, the input detectionnominal voltage can be set to 12V, 24V or 48V for BI1 and BI2, and to 24V or 48V for BI3-BI6.

The binary input detection threshold voltage (i.e. minimum operating voltage) is normally set at77V and 154V for supply voltages of 110V and 220V respectively. In the case of 24V and 48Vsupplies, the normal thresholds are 16.8V and 33.6V respectively. Binary inputs can be configuredfor operation in a Trip Circuit Supervision (TCS) scheme by setting the [TCSPEN] switch to“Enable”. For the case where TCS using 2 binary inputs is to be applied (refer to Section 3.3.3),then the binary input detection threshold of BI1 and BI2 should be set to less than half of the rateddc supply voltage.

GRE130 provides 5 auxiliary relays which is composed of one auxiliary relay FAIL for the relayfail output and four programmable auxiliary relays BO1 to BO4.

The reset time of the tripping output relay following fault clearance can be programmed. Thesetting is respective for each output relay.

The signals shown in the signal list in Appendix A can be assigned to output relays BO1 to BO4individually or in arbitrary combinations. The output relays BO1 and BO2 connect to CB OPEN /CLOSE for CB control. The CB close control switch ｜ is linked to BO1 and the CB open control

switch ○ is linked to BO2, when the control function is enabled.

Signals can be combined using either an AND circuit or OR circuit with 4 gates each as shown inFigure 3.2.3. The output circuit can be configured according to the setting menu. Appendix Gshows the factory default settings.

Further, each BO has a programmable reset characteristic, settable for instantaneous drop-off“Ins”, for delayed drop-off “Dl”, for dwell operation “Dw” or for latching operation “Lat” by thescheme switch [RESET]. The time of the delayed drop-off “Dl” or dwell operation “Dw” can beset by TBO. When “Dw” is selected, the BO outputs for the TBO set time if the input signal doesnot continue on the TBO set time. If the input signal continues, the BO output is continuous for thetime duration of the input signal.

When the relay is latched, it can be reset with the RESET key on the relay front panel or a binary

input. This resetting resets all the output relays collectively.The relay failure contact closes when a relay defect or abnormality in the power supply circuit is

3.3 Automatic Supervision

3.3.1 Basic Concept of Supervision

Although the protection system is in a non-operating state under normal conditions, it

continuously monitors the power system in order to detect a fault which may occur at any time,and must operate for the fault without fail. Therefore, the automatic supervision function, whichchecks the health of the protection system during normal operation, plays an important role. TheGRE130 implements an automatic supervision function, based on the following concepts:

The supervising function should not affect the protection performance.

Perform supervision with no omissions wherever possible.

When a failure occurs, it is recorded as an Alarm record, the user should be easily able toidentify the location of the failure.

Under relay failure detection , CB open control is enabled, but CB close control is disabled.

3.3.2 Relay Monitoring

The relay is supervised by the following functions.

AC input imbalance moni toring

The AC current input is monitored to check that the following equation is satisfied and the healthof the AC input circuit is verified.

Zero sequence voltage monitoring for [APPL]= “3PN” setting

|Va + V b + Vc| / 3 6.35 (V)

Negative sequence voltage monitoring for [APPL]≠ “1PN” or “1PP” setting

|Va + a2V b + aVc| / 3 6.35 (V) where, a = Phase shift operator of 120, a2 = Phase shift

operator of 240

The zero sequence monitoring and negative sequence monitoring allow high sensitivity detectionof failures that have occurred in the AC input circuits.

The negative sequence voltage monitoring allows high sensitivity detection of failures in thevoltage input circuit, and it is effective for detection particularly when cables have been connectedwith the incorrect phase sequence.

A/D accuracy checking

An analog reference voltage is applied to a prescribed channel in the analog-to-digital (A/D)converter, and a check is made to ensure that the data after A/D conversion is within a prescribedrange, and that the A/D conversion characteristics are correct.

Watchdog Timer

A hardware timer that is cleared periodically by the relay software is provided, to check that therelay software is running normally.

Power supply Monitoring

The secondary voltage level is monitored, and a check is made to ensure that the DC voltage iswithin a prescribed range.

3.3.3 Trip Circui t Supervision

The circuit breaker tripping control circuit can be monitored by either one or two binary inputs, asdescribed below.

Trip Circuit Supervision using 1 binary input

The circuit breaker tripping control circuit can be monitored using a binary input. Figure 3.3.1shows a typical scheme. When the trip circuit is intact , a small current flows through the binaryinput, the circuit breaker auxiliary contacts and the trip coil. This current flows for both the breaker open and closed conditions. Then the logic signal output of the binary input circuit TCFAIL is "1" under healthy conditions.

If the trip supply is lost or if a connection becomes open circuit, then the binary input resets andTC FAIL becomes "0". Figure 3.3.2 shows the scheme logic. A trip circuit fail alarm TCSV isoutput when the TC FAIL output is "0". If the trip circuit failure is detected, then “ALARM” LEDis lit and “Err: TC” is displayed in LCD message.

Monitoring is enabled by setting the scheme switch [TCSPEN] to "ON" or "OPT-ON" and one BIis selected for "TCFALM". When "OPT-N" is selected, monitoring is enabled only while the CBis closed.

Monitoring is enabled by setting scheme switch [TCSPEN] to "ON" or "OPT-ON" and the twoBIs selected for "TCFALM". When "OPT-ON" is selected, monitoring is enabled only while theCB is closed. TCS using 2BIs should be applied using BI1 and BI2 for the BI inputs. For TCSusing 2BIs the BI nominal operating voltage ([BITHR1]) should be set to a value of approximatelyhalf that of the trip supply voltage. If the trip supply voltage is 110V (or 24V) , [BITHR1] can be

set at "48" (or "12").GRE130 Circuit Breaker

3.3.4 Circui t Breaker Monitoring

The relay provides the following circuit breaker monitoring functions.

Circuit Breaker State Monitoring

Circuit breaker state monitoring is provided for checking the health of the circuit breaker (CB). Iftwo binary inputs are programmed to the functions ‘CB_N/O_CONT’ and ‘CB_N/C_CONT’,

then the CB state monitoring function becomes active. Under normal circumstances these inputsare in opposite states. Figure 3.3.4 shows the scheme logic. If both show the same state for a periodof five seconds, then a CB state alarm CBSV operates and “Err:CB” and “CB err” are displayed inan LCD message and event record message respectively.

The monitoring can be enabled or disabled by setting the scheme switch [CBSMEN].

Normally open and normally closed contacts of the CB are connected to binary inputs BIm andBIn respectively, and the functions of BIm and BIn are set to “CBOPN=ON” and “CBCLS=ON”respectively. (Refer to Section 4.2.6.8.)

Circuit Breaker Condition Monitoring

Periodic maintenance of a CB is required in order to check the trip circuit, the operatingmechanism and the interrupting capability. Generally, maintenance is based on a time interval or anumber of fault current interruptions.

The following CB condition monitoring functions are provided to determine the time formaintenance of a CB:



39

6 F 2 T 0 1 7 6

The number of trip operations are counted for maintenance of the trip circuit and CBoperating mechanism. The trip counter increments the number of tripping operations

performed. An alarm is issued and informs the user of the time for maintenance when the countexceeds a user-defined setting TCALM.The trip count alarm can be enabled or disabled by setting the scheme switch [TCAEN].

Operating time monitoring is provided for CB mechanism maintenance. It checks the CBoperating time and the need for mechanism maintenance is advised if the CB operation isslow. The operating time monitor records the time between issuing the tripping signal and the

phase currents falling to zero. An alarm is issued when the operating time for any phaseexceeds a user-defined setting OPTALM. The operating time is set in relation to the specifiedinterrupting time of the CB. The operating time alarm can be enabled or disabled by setting thescheme switch [OPTAEN].

The maintenance program should comply with the switchgear manufacturer’s instructions.

3.3.5 Failure Alarms

When a failure is detected by the automatic supervision, it is followed with an LCD message, LEDindication, external alarm and event recording. Table 3.3.1 summarizes the supervision items andalarms.

The LCD messages are shown on the "Auto-supervision" screen, which is displayed automaticallywhen a failure is detected or displayed by pressing ▼ key. The event record messages are shownon the "Event record" screen by opening the "Record" sub-menu.

The alarms are retained until the failure is recovered.

The alarms can be disabled collectively by setting the scheme switch [AMF] to "OFF". The settingis used to block unnecessary alarms during commissioning, test or maintenance.

When the Watchdog Timer detects that the software is not running normally, LCD display and

event recording of the failure may not function normally.Table 3.3.1 Supervision Items and Alarms

3.4 Record ing Function

The GRE130 is provided with the following recording functions:

Fault recording

Event recordingDisturbance recording

Counters

These records are displayed on the LCD screen of the relay front panel or on a local or remote PC.

3.4.1 Fault Recording

Fault recording is initiated by a tripping command from the GRE130 and the following items arerecorded for one fault:

Date and timeTrip modeOperating phasePower system quantitiesUser configurable initiation

Up to the 4 most-recent faults are stored as fault records. If a new fault occurs when 4 faults have been stored, the record of the oldest fault is deleted and the record of the latest fault is then stored.

Date and time occurrence

This is the time at which a tripping command has been initiated. The time resolution is 1 ms usingthe relay internal clock.

Trip mode

This shows the protection scheme such as OV1, UV1 etc. that output the tripping command.

Operating phase

This is the phase to which a tripping command is output.

Power sys tem quantities

The following power system quantities are recorded both pre-fault and post-fault.

- Magnitude and phase angle of phase voltages (Va, V b, Vc)

- Magnitude and phase angle of phase-to-phase voltages (Vab, V bc, Vca)

- Magnitude and phase angle of zero sequence voltage which is measured directly in the form ofthe system residual voltage (Ve)

- Magnitude and phase angle of symmetrical component voltages (V1, V2, V0)

- Frequency (f)

3.4.2 Event Recording

The events shown in Appendix B are recorded with a 1 ms resolution time-tag when the status

changes. For BI1 to BI6 commands, the user can select the items to be recorded and their statuschange mode to initiate recording as below.



42

6 F 2 T 0 1 7 6

One of the following four modes is selectable.

Modes Setting

Not to record the event. N

To record the event when the status changes to "operate". O

To record the event when the status changes to "reset". R

To record the event when the status changes both to "operate" and "reset". B

For the setting, see Section 4.2.6.5. The default setting is "B"

Up to 200 records can be stored. If an additional event occurs after 200 records have been stored,the oldest event record is overwritten. The LCD display only shows 100 records. All event records(200 records) can be displayed on a PC. For how to download all of the event records onto a PCrefer to the RSM100 instruction manual.

3.4.3 Disturbance Recording

Disturbance recording is initiated when the overvoltage or undervoltage starter element operatesor a tripping command is initiated. Further, disturbance recording is initiated when a startcommand is initiated. The user can configure four disturbance record triggers.

The records include a maximum of 8 analogue signals as shown in Table 3.4.1, 32 binary signalsand the dates and times at which recording started. Any binary signal shown in Appendix B can beassigned using the binary signal setting of a disturbance record.

The LCD display only shows the dates and times of the disturbance records stored. Details can bedisplayed on a PC. For how to obtain disturbance records on a PC, see the RSM softwareinstruction manual.

The pre-fault recording time can be set between 0.1 and 4.9s and the post-fault recording time can be set between 0.1 and 3.0s. But the combined duration for the pre-fault and post-fault recordingtimes is 5.0s or less. The number of records stored depends on the post-fault recording time. Theapproximate relationship between the post-fault recording time and the number of records storedis shown in Table 3.4.2.

Note: If the recording time setting is changed, the records stored so far are deleted.

3.5 Metering Function

The GRE130 relay measures current and demand values of phase and phase-to-phase voltages,residual voltage, symmetrical component voltages and frequency. The measurement data shown below is displayed on the LCD of the relay front panel or on a local or remote PC.

The following quantities are measured and updated every second.- Magnitude and phase angle of phase voltage (Va, V b, Vc)

- Magnitude and phase angle of phase-to-phase voltage (Vab, V bc, Vca)

- Magnitude and phase angle of symmetrical component voltage (V1, V2, V0)

- Frequency (f)

- Maximum and minimum of frequency (f: max, min)

- Frequency rate-of-change (df / dt)

The above system quantities are displayed in values on the primary side or on the secondary sideas determined by a setting. To display accurate values, it is necessary to set the VT ratio as well.

For the setting method, see "Setting the metering" in 4.2.6.6 and "Setting the parameter" in 4.2.6.7.In the case of the maximum and minimum values display above, the measured quantity is averagedover a rolling 15 minute time window, and the maximum and minimum recorded average valuesare shown on the display screen.

The displayed quantities depend on [APPL] settings and relay model as shown in Table 3.5.1.Input voltage greater than 0.06V at the secondary side are required for measurement.

Phase angles above are expressed taking the positive sequence voltage as a reference phase angle,where leading phase angles are expressed as positive, (+).

CAUTION

Modification of settings : Care should be taken when modifying settings for "active group","scheme switch" and "protection element" in the "Protection" menu. Dependencies exist betweenthe settings in the various menus, with settings in one menu becoming active (or inactive)depending on the selection made in another menu. Therefore, it is recommended that all necessarysettings changes be made while the circuit breaker tripping circuit is disconnected.

Alternatively, if it is necessary to make settings changes with the tripping circuit active, then it isrecommended to enter the new settings into a different settings group, and then change the "activegroup" setting, thus ensuring that all new settings become valid simultaneously.

4.2.6.1 Setting Method

4.3 Personal Computer Interface

The relay can be operated from a personal computer using a USB port on the front panel.Using a personal computer, the following analysis and display of fault currents are available inaddition to the items available on the LCD screen.

Display of current waveform: Oscillograph display

Symmetrical component analysis: On arbitrary time span

Harmonic analysis: On arbitrary time span

Frequency analysis: On arbitrary time span

For details, see the separate instruction manual "PC INTERFACE RSM100".

4.4 Modbus Interface

GRE130 supports the Modbus communication protocol. This protocol is mainly used when the

relay communicates with a control system and is used to transfer the following measurement andstatus data from the relay to the control system. (For details, see Appendix L.)

Measurement data: current

Status data: events, fault indications, counters, etc.

Setting data

Remote CB operation: Open / Close

Time setting / synchronization

The protocol can be used via the RS-485 port on the relay rear panel.

The relay supports two baud-rates 9.6kbps and 19.2kbps. These are selected by setting. SeeSection 4.2.6.4.

4.5 Clock Function

The clock function (Calendar clock) is used for time-tagging for the following purposes:

Event records

Disturbance records

Fault records

The calendar clock can run locally or be synchronised with an external clock such as the binary

time standard input signal or Modbus. This can be selected by setting.

The “clock synchronise” function synchronises the relay internal clock to the binary input signal by the following method. Since the BI signal is an “ON” or “OFF” signal which cannot expressyear-month-day and hour-minute-second etc, synchronising is achieved by setting the number ofmilliseconds to zero. This method will give accurate timing if the synchronising BI signal is inputevery second.

Synchronisation is triggered by an “OFF” to “ON” (rising edge) transition of the BI signal. Whenthe trigger is detected, the millisecond value of the internal clock is checked, and if the value is between 0~500ms then it is rounded down. If it is between 500~999ms then it is rounded up (ie thenumber of seconds is incremented).



103

6 F 2 T 0 1 7 6

When the relays are connected with the RSM system as shown in separate volume "PCINTERFACE RSM100" and "RSM" is selected in the time synchronisation setting, the calendarclock of each relay is synchronised with the RSM clock. If the RSM clock is synchronised with anexternal time standard, then all the relay clocks are synchronised with the external time standard.

5.3 Electrostatic Discharge

CAUTION

Do not remove the relay PCB from the relay case since electronic components on the modules arevery sensitive to electrostatic discharge.

5.4 Handling Precautions

A person's normal movements can easily generate electrostatic potentials of several thousand

volts. Discharge of these voltages into semiconductor devices when handling electronic circuitscan cause serious damage. Often, this damage may not be immediately apparent, but the reliabilityof the circuit will have been reduced.

The electronic circuits are completely safe from electrostatic discharge when housed in the case.Do not expose them to risk of damage.

The relay unit incorporates the highest practical protection for its semiconductor devices.However, if it becomes necessary to withdraw the relay unit, precautions should be taken to preserve the high reliability and long life for which the equipment has been designed andmanufactured.

CAUTION Do not pass the relay unit to another person without first ensuring you are both at the same

electrostatic potential. Shaking hands achieves equipotential.

Place the relay unit on an anti-static surface, or on a conducting surface which is at the same potential as yourself.

Do not place the relay unit in polystyrene trays.

It is strongly recommended that detailed investigations on electronic circuitry should be carriedout in a Special Handling Area.

5.5 External ConnectionsExternal connections for each relay model are shown in Appendix F.

6.5 Function Test

CAUTION

The function test may cause the output relays to operate including the tripping output relays.Therefore, the test must be performed with tripping circuits disconnected.

6.5.1 Measuring Element

Measuring element characteristics are realized using software, so it is possible to verify the overallcharacteristics by checking representative points.

Operation of the element under test is observed by assigning the signal number to a configurableLED or a binary output relay.

Note: The voltage level at the monitoring jacks is +5V for logic level "1" and less than 0.1V for

logic level "0".

CAUTION

Use test equipment with more than 1 k of internal impedance when observing the outputsignal at the monitoring jacks.

Do not apply an external voltage to the monitoring jacks.

Do not leave the A or B terminal shorted to 0V terminal for a long time.

In the case of a three-phase element, it is sufficient to test for a representative phase. The A-phaseelement is selected hereafter. Further, the [APPLCT] settings are selected “3P” and “3PV”.

Note: The operating time test for the relay measuring elements at monitoring jacks A or Bdoes not include operation of the binary output. An overall operating time test, ifrequired, should be measured at a binary output relay.

6.7 Maintenance

6.7.1 Regular Testing

The relay is almost completely self-supervised. The circuits that can not be supervised are binaryinput and output circuits and human interfaces.

Therefore, regular testing is minimised to checking the unsupervised circuits. The test proceduresare the same as described in Sections 6.4.1, 6.4.2 and 6.4.3.

6.7.2 Failure Tracing and Repair

Failures will be detected by automatic supervision or regular testing.

When a failure is detected by supervision, a remote alarm is issued from the binary output FAILrelay and the failure is indicated on the front panel by the LED indicators or LCD display. It is alsorecorded in the event record.

Failures detected by supervision are traced by checking the "Err: " screen on the LCD. Table 6.7.1shows LCD messages and failure locations.

The locations marked with (1) have a higher probability than locations marked with (2).

Table 6.7.1 LCD Message and Failure Location

Message Failure location

Err: DRIVER (BI,BO circuit)(1) (2)

( ): Probable failure location in the relay unit including its peripheral circuits.

* ; Error level set in VT supervision function.

Alarms detected by the relay self-supervision are traced by checking the "ALM: " screen on theLCD. Table 6.7.2 shows LCD messages and alarm locations.

( ): Probable failure location in the relay unit including peripheral circuits.



123

6 F 2 T 0 1 7 6

If there is no message is shown on the LCD it means that the failure location is either in the powersupply circuit or in the microprocessors. If the "ALARM" LED is off, the failure is in the powersupply circuit. If the LED is lit, the failure is in the microprocessors. Replace the relay unit in bothcases after checking if the correct voltage is applied to the relay.

If a failure is detected by the automatic supervision function or regular testing, replace the failed

relay unit.Note: When a failure or an abnormality is detected during a regular test, confirm the following

first:

- Test circuit connections are correct.

- Correct power voltage is applied.

- Correct AC inputs are applied.

- Test procedures comply with those stated in the manual.

6.7.3 Replacing Failed Relay Unit

If the failure is identified to be in the relay and the user has a spare relay, the user can recover the protection by replacing the relay.

Repairs at site should be limited to relay replacement. Maintenance at component level is notrecommended.

Check that the replacement relay unit has an identical Model Number and relay version (softwaretype form) as the relay to be replaced.

The Model Number is indicated on the front of the relay. For the relay version, see Section 4.2.5.1.

Replacing the relay unit

CAUTION After replacing the relay unit, check the settings.

The procedure for relay withdrawal and insertion is as follows:

Switch off the DC power supply.

Hazardous voltage may remain in the DC circuit when the power supply isde-energized. It will take approximately 30 seconds for the voltage todischarge.

Remove the terminal blocks from the relay leaving the wiring in place. To remove the relay unit from the panel, the attachment screws must be removed. Insert the (spare) relay unit following the reverse procedure.

CAUTION To avoid risk of damage: When the attachment kits are removed, support the relay to ensure that it does not fall

from panel.

Ensure that the relay front cover panel is closed throughout the operation.

6.7.4 Resumption of Service

After replacing the failed relay unit or repairing failed external circuits, take the following procedures to restore the relay to the service.

Switch on the power supply and confirm that the "IN SERVICE" green LED is lit and the"ALARM" red LED is not lit.

Connect the AC inputs and reconnect the trip outputs.

6.7.5 StorageThe spare relay should be stored in a dry and clean room. Based on IEC Standard 60255-6 the

storage temperature should be 25C to +70C, but the temperature of 0C to +40C isrecommended for long-term storage.

WARNING



124

6 F 2 T 0 1 7 6

7. Putting Relay into Service

The following procedure must be adhered to when putting the relay into service after finishing thecommissioning tests or maintenance tests.

Check that all the external connections are correct.

Check the settings of all measuring elements, timers, scheme switches, recordings and clockare correct.

In particular, when settings are changed temporarily for testing, be sure to restore them.

Clear any unnecessary records on faults, alarms, events, disturbances and counters which arerecorded during the tests.

Press ▼ key and check that no failure message is displayed on the "Auto-supervision" screen.

Check that the green "IN SERVICE" LED is lit and no other LEDs are lit on the front panel.
