2.2.2 Setting groupsMost of the protection functions of the relay have two setting groups.These groups are useful for example when the network topology ischanged frequently. The active group can be changed by a digitalinput, through remote communication or locally by using the localpanel.

The active setting group of each protection function can be selectedseparately. Figure 2.7 shows an example where the changing of theI> setting group is handled with digital input one (SGrpDI). If thedigital input is TRUE, the active setting group is group two andcorrespondingly, the active group is group one, if the digital input isFALSE. If no digital input is selected (SGrpDI = -), the active groupcan be selected by changing the value of the parameter SetGrp.

Figure 2.7: Example of protection submenu with setting group parameters

The changing of the setting parameters can be done easily. Whenthe desired submenu has been found (with the arrow keys), press

to select the submenu. Now the selected setting group isindicated in the down-left corner of the display (See Figure2.8). Set1is setting group one and Set2 is setting group two. When the neededchanges, to the selected setting group, have been done, pressor to select another group ( is used when the active settinggroup is 2 and is used when the active setting group is 1).

• Rated phase CT secondary current (Isec)

• Rated input of the relay [Iinput]. 5 A or 1 A. This is specified inthe order code of the device.

• Rated phase CT’ primary current (I’nom)

• Rated phase CT’ secondary current (I’sec)

• Rated input of the relay [I’input]. 5 A or 1 A. This is specified inthe order code of the device.

• Rated value of I0 CT primary current (Ionom)

• Rated value of I0 CT secondary current (Iosec)

• Rated I01 input of the relay [Ioinp]. 5 A or 1 A. This is specifiedin the order code of the device.

• Rated value of I02 CT primary current (Io2nom)

• Rated value of I02 CT secondary current (Io2sec)

• Rated I02 input of the relay [Io2inp]. 5A, 1 A or 0.2 A. This isspecified in the order code of the device.

The rated input values are usually equal to the rated secondary valueof the CT.

The rated CT secondary may be greater than the rated input but thecontinuous current must be less than four times the rated input. Incompensated, high impedance earthed and isolated networks usingcable transformer to measure residual current I0, it is quite usual touse a relay with 1 A or 0.2 A input although the CT is 5 A or 1A. Thisincreases the measurement accuracy.

The rated CT secondary may also be less than the rated input butthe measurement accuracy near zero current will decrease.

Furthermore, the interlockingbetween objects can be configured in the same blocking matrix ofthe VAMPSET software. For more information, please refer to theVAMPSET manual (VVAMPSET/EN M/xxxx).

3 VAMPSET PC software

The PC user interface can be used for:

• On-site parameterization of the relay

• Loading relay software from a computer

• Reading measured values, registered values and events to acomputer

• Continuous monitoring of all values and events

Two RS 232 serial ports are available for connecting a local PC withVAMPSET to the relay; one on the front panel and one on the rearpanel of the relay. These two serial ports are connected in parallel.However, if the connection cables are connected to both ports, onlythe port on the front panel will be active. To connect a PC to a serialport, use a connection cable of type VX 003-3.

The VAMPSET program can also use TCP/IP LAN connection.Optional hardware is required.

There is a free of charge PC program called VAMPSET availablefor configuration and setting of VAMP relays. Please download thelatest VAMPSET.exe from our web page. For more information aboutthe VAMPSET software, please refer to the user’s manual with thecode VVAMPSET/EN M/xxxx. Also the VAMPSET user’s manual isavailable at our web site.

3.1 Folder viewIn VAMPSET version 2.2.136, a feature called ”Folder view” wasintroduced.

The idea of folder view is to make it easier for the user to work withrelay functions inside VAMPSET. When folder view is enabled,VAMPSET gathers similar functions together and places themappropriately under seven different folders (GENERAL,MEASUREMENTS, INPUTS/OUTPUTS, MATRIX, LOGS andCOMMUNICATION). The contents (functions) of the folders dependon the relay type and currently selected application mode.

Folder view can be enabled in VAMPSET via ProgramSettings dialog(Settings -> Program Settings), see Figure 3.1.

NOTE: It is possible to enable/ disable the folder view only when VAMPSETis disconnected from the relay and there is no configuration fileopened.

When folder view is enabled, folder buttons become visible inVAMPSET, see Figure3.2. Currently selected folder appears in bold.

4 Introduction

• Built-in, self-regulating ac/dc converter for auxiliary power supplyfrom any source within the range from 40 to 265 Vdc or Vac. Thealternative power supply is for 18 to 36 Vdc.

• Built-in disturbance recorder for evaluating all the analogue anddigital signals.

• Eight (8) programmable stages for alarming or protectionpurposes

4.2 Principles of numerical protectiontechniquesThe device is using numerical technology. This means that all thesignal filtering, protection and control functions are implementedthrough digital processing.

The numerical technique used is primarily based on an adapted FastFourier Transformation (FFT) algorithm. Synchronized sampling ofthe measured voltage and current signals is used. The sample rateis 32 samples/cycle within the frequency range 45 Hz – 65 Hz. Thefrequency is measured from the current signals L1 and L2 and usedto synchronize the sampling rate. Therefore secondary testing of abrand new device should be started by injecting stabile systemfrequency current signal in nominal magnitude. The learned frequencyis used for sampling rate synchronization when the measured currentis less than 20% of nominal value. The local network frequency canalso be manually given for the relay.

Apart from the FFT calculations, some protection functions alsorequire the symmetrical components to be calculated for obtainingthe positive, negative and zero phase sequence components of themeasured quantity. For example, the function of the unbalanced loadprotection stage is based on the use of the negative phase sequencecomponent of the current.

Figure 4.1 shows a hardware block diagram of the relay. The maincomponents are the current and voltage inputs, digital input elements,output relays, A/D converters and the microcomputer and a powersupply unit.

Figure 4.2 shows the inputs and outputs of a general protectionfunction. The FFT block is calculating the fundamental frequencyphasors and also harmonics used by some protection functions. Theblock matrix is used for simple interlocking. (More complexinterlocking is done with the user's programmable logic). The outputmatrix is used to connect the pick-up and trip signals from protectionblocks to the output relays and indicators.

Figure 4.3 shows a block diagram of a basic overcurrent orovervoltage function with definite and inverse operation time.

4 Introduction4.2 Principles of numerical protection techniques

5 Protection functions

Each protection stage can independently be enabled or disabledaccording to the requirements of the intended application.

5.1 Maximum number of protection stagesin one applicationThe device limits the maximum number of enabled stages to about30, depending of the type of the stages.

For more information, please see the configuration instructions inChapter 2.4 Configuration and parameter setting.

5.2 General features of protection stagesSetting groups

Most stages have two setting groups. Changing between settinggroups can be controlled manually or using any of the digital inputs,virtual inputs, virtual outputs or LED indicator signals. By using virtualI/O the active setting group can be controlled using the local paneldisplay, any communication protocol or using the inbuiltprogrammable logic functions.

Forcing start or trip condition for testing

The status of a protection stage can be one of the followings:

• Ok = ‘-‘The stage is idle and is measuring the analog quantity for theprotection. No fault detected.

• BlockedThe stage is detecting a fault but blocked by some reason.

• StartThe stage is counting the operation delay.

• TripThe stage has tripped and the fault is still on.

The blocking reason may be an active signal via the block matrixfrom other stages, the programmable logic or any digital input. Somestages also have inbuilt blocking logic. For example an underfrequency stage is blocked if voltage is too low. For more detailsabout block matrix, see Chapter 8.5 Blocking matrix.

49V265M/en M/A005

5 Protection functions

Forcing start or trip condition for testing purposes

There is a "Force flag" parameter which, when activated, allowsforcing the status of any protection stage to be "start" or "trip" for ahalf second. By using this forcing feature any current or voltageinjection to the device is not necessary to check the output matrixconfiguration, to check the wiring from the output relays to the circuitbreaker and also to check that communication protocols are correctlytransferring event information to a SCADA system.

After testing the force flag will automatically reset 5-minute after thelast local panel push button activity.

The force flag also enables forcing of the output relays and forcingthe optional mA outputs.

Force flag can be found in relays menu.

Start and trip signals

Every protection stage has two internal binary output signals: startand trip. The start signal is issued when a fault has been detected.The trip signal is issued after the configured operation delay unlessthe fault disappears before the end of the delay time.

Output matrix

Using the output matrix the user connects the internal start and tripsignals to the output relays and indicators. For more details, seeChapter 8.4 Output matrix.

Blocking

Any protection function, except arc protection, can be blocked withinternal and external signals using the block matrix (Chapter 8.5Blocking matrix). Internal signals are for example logic outputs andstart and trip signals from other stages and external signals are forexample digital and virtual inputs.

When a protection stage is blocked, it won't pick-up in case of a faultcondition is detected. If blocking is activated during the operationdelay, the delay counting is frozen until the blocking goes off or the

V265M/en M/A00550

5 Protection functions5.2 General features of protection stages

pick-up reason, i.e. the fault condition, disappears. If the stage isalready tripping, the blocking has no effect.

Retardation time

Retardation time is the time a protection relay needs to notice, thata fault has been cleared during the operation time delay. Thisparameter is important when grading the operation time delay settingsbetween relays.

DELAY SETTING > t + tFAULT RET

TRIP CONTACTS

t < 50 msRET

tFAULT

RetardationTime

Figure 5.1: Definition for retardation time. If the delay setting would be slightlyshorter, an unselective trip might occur (the dash line pulse).

For example when there is a big fault in an outgoing feeder, it mightstart i.e. pick-up both the incoming and outgoing feeder relay.However the fault must be cleared by the outgoing feeder relay andthe incoming feeder relay must not trip. Although the operating delaysetting of the incoming feeder is more than at the outgoing feeder,the incoming feeder might still trip, if the operation time difference isnot big enough. The difference must be more than the retardationtime of the incoming feeder relay plus the operating time of theoutgoing feeder circuit breaker.

Figure 5.1 shows an overvoltage fault seen by the incoming feeder,when the outgoing feeder does clear the fault. If the operation delaysetting would be slightly shorter or if the fault duration would beslightly longer than in the figure, an unselective trip might happen(the dashed 40 ms pulse in the figure). In VAMP devices theretardation time is less than 50 ms.

Reset time (release time)

Figure 5.2 shows an example of reset time i.e. release delay, whenthe relay is clearing an overcurrent fault. When the relay’s tripcontacts are closed the circuit breaker (CB) starts to open. After theCB contacts are open the fault current will still flow through an arcbetween the opened contacts. The current is finally cut off when thearc extinguishes at the next zero crossing of the current. This is thestart moment of the reset delay. After the reset delay the trip contactsand start contact are opened unless latching is configured. The

51V265M/en M/A005

5.2 General features of protection stages5 Protection functions

precise reset time depends on the fault size; after a big fault the resettime is longer. The reset time also depends on the specific protectionstage.

The maximum reset time for each stage is specified in Chapter 12.3Protection functions. For most stages it is less than 95 ms.

Hysteresis or dead band

When comparing a measured value against a pick-up value, someamount of hysteresis is needed to avoid oscillation near equilibriumsituation. With zero hysteresis any noise in the measured signal orany noise in themeasurement itself would cause unwanted oscillationbetween fault-on and fault-off situations.

5 Protection functions5.2 General features of protection stages

5.3 Frequent start protection N> (66)The simplest way to start an asynchronous motor is just to switchthe stator windings to the supply voltages. However every such startwill heat up the motor considerably because the initial currents aresignificantly above the rated current.

If the motor manufacturer has defined the maximum number of startswithin an hour or/and the minimum time between two consecutivestarts this stage is easy to apply to prevent too frequent starts.

When current has been less than 10% of the motor nominal currentand then exceeds the value Motor start detection current of IST>(Stall protection stage), situation is recognized as a motor start. Afterthe recognition of the motor start if current drops to a less than 10% of the motor nominal current, stage considers motor to be stopped.

Frequent start protection stage will provide N> alarm signal whenthe second last start has been done and remains active until themaximum amount of motor starts are reached or one hour of time ispassed.

The N> motor start inhibit signal activates after starting the motorand remains active a period of time that is defined for parameter Mintime between motor starts. After the given time has passed, inhibitsignal returns to inactive state.

When start counter of stage reaches the value defined for Max. motorstarts/hour, N> motor start inhibit signal activates and remains activeuntil one hour has passed.

Frequent start protection stage correlation to output contacts isdefined in output matrix menu. See Chapter 8.4 Output matrix.Figure 5.5 shows an application.

5.4 Differential overcurrent protection ΔI>(87)The differential overcurrent protection comprises two separatelyadjustable stages, stage ΔI> and stage ΔI>>.

The differential protection is based on winding currents differencebetween IL and I’L side. In Yy0 connection measured currents arealso winding currents, see Figure 5.6. In motor and generatorapplications the connection group is always Yy0 and measuredcurrents are also winding currents.

5.5 Overcurrent protection I> (50/51)Overcurrent protection is used against short circuit faults and heavyoverloads.

The overcurrent function measures the fundamental frequencycomponent of the phase currents. The protection is sensitive for thehighest of the three phase currents. Whenever this value exceedsthe user's pick-up setting of a particular stage, this stage picks upand a start signal is issued. If the fault situation remains on longerthan the user's operation delay setting, a trip signal is issued.

Two independent stages

There are two separately adjustable overcurrent stages: I>, I>>, I’>and I’>>. The first stage I> can be configured for definite time (DT)or inverse time operation characteristic (IDMT). The stage I>> hasdefinite time operation characteristic. By using the definite delay typeand setting the delay to its minimum, an instantaneous (ANSI 50)operation is obtained.

Figure 5.11 shows a functional block diagram of the I> overcurrentstage with definite time and inverse time operation time. Figure 5.12shows a functional block diagram of the I>> overcurrent stage withdefinite time operation delay.

Inverse operation time

Inverse delay means that the operation time depends on the amountthe measured current exceeds the pick-up setting. The bigger thefault current is the faster will be the operation. Accomplished inversedelays are available for the I> stage. The inverse delay types aredescribed in Chapter 5.17 Inverse time operation. The device willshow the currently used inverse delay curve graph on the local paneldisplay.

Inverse time limitation

The maximum measured secondary current is 50 x IN. This limitsthe scope of inverse curves with high pick-up settings. SeeChapter 5.17 Inverse time operation for more information.

Setting groups

There are two settings groups available for each stage. Switchingbetween setting groups can be controlled by digital inputs, virtualinputs (communication, logic) and manually.

5.5 Overcurrent protection I> (50/51)5 Protection functions

5.5.1 Remote controlled overcurrent scalingPick-up setting of the three over current stages can also be controlledremotely. In this case only two scaling coefficients are possible:100% (the scaling is inactive) and any configured value between10% - 200% (the scaling is active). When scaling is enabled allsettings of group one are copied to group two but the pick-up valueof group two is changed according the given value (10-200%).

• This feature can be enabled/disabled via VAMPSET or by usingthe local panel. When using VAMPSET the scaling can beactivated and adjusted in the “protection stage status 2” –menu.When using the local panel similar settings can be found fromthe “prot” -menu.

• It is also possible to change the scaling factor remotely by usingthe modbus TCP –protocol. When changing the scaling factorremotely value of 1% is equal to 1. Check the correct modbusaddress for this application from the VAMPSET or from thecommunication parameter list.

Figure 5.13: Remote scaling example.

In the Figure 5.13 can be seen the affect of remote scaling. Afterenabling group is changed from group one to group two and allsettings from group one are copied to group two. The difference isthat group two uses scaled pick-up settings.

NOTE: When remote scaling function is used, it replaces all the settings ofgroup 2. So this function cannot be used simultaneously with normalgroup change.

5.6 Stall protection IST> (48)The stall protection unit IST> measures the fundamental frequencycomponent of the phase currents.

Stage IST> can be configured for definite time or inverse timeoperation characteristic.

The stall protection stage protects the motor against prolongeddirect-on-line (DOL) starts caused by e.g. a stalled rotor, too highinertia of the load or too low voltage. This function is sensitive to thefundamental frequency component of the phase currents.

The IST> stage can be configured for definite operation time or inversetime operation characteristic. For a weak voltage supply the inversecharacteristics is useful allowing more start time when a voltage dropdecreases the start current and increases the start time. Equation5.1defines the inverse operation time. Figure 5.15 shows an exampleof the inverse characteristics.

5.6.1 Motor statusThere are three possible startus for a motor: stopped, starting orrunning.

• Motor stopped: Motor average current is less than 10% of themotor nominal current.

• Motor starting: To reach the starting position motor has to bestopped for least 500ms before starting. Motor average currenthas to increase above the motor start detection current (settingvalue) within 200ms. Motor will remain starting as long as theterms for turning into running condition are not filled.

• Motor running: Motor is able to turn into a running position fromboth stopped and starting position. Low limit for motor runningis 20% of the motors nominal and the high limit for motor runningis 120% of the motors nominal current.

Figure 5.16: Motor status via VAMPSETand local panel.

The status of the motor can be viewed via VAMPSET -software orby looking from the local panel of the relay (Mstat). Statuses Startingand running can be found from the output –and block matrix.Therefore it is possible to use these signals for tripping or indicationand for blocking purposes.

5.10 Earth fault protection I0> (50N/51N)The undirectional earth fault protection is to detect earth faults in lowimpedance earthed networks. In high impedance earthed networks,compensated networks and isolated networks undirectional earthfault can be used as back-up protection.

The undirectional earth fault function is sensitive to the fundamentalfrequency component of the residual current 3I0. The attenuation ofthe third harmonic is more than 60 dB. Whenever this fundamentalvalue exceeds the user's pick-up setting of a particular stage, thisstage picks up and a start signal is issued. If the fault situationremains on longer than the user's operation time delay setting, a tripsignal is issued.

Input signal selection

Each stage can be connected to supervise any of the following inputsand signals:

• Input I01 for all networks other than rigidly earthed.

• Input I02 for all networks other than rigidly earthed.

• Calculated signal I0Calc for rigidly and low impedance earthednetworks. I0Calc = IL1 + IL2 + IL3.

Intermittent earth fault detection

Short earth faults make the protection to start (to pick up), but willnot cause a trip. (Here a short fault means one cycle or more. Forshorter than 1 ms transient type of intermittent earth faults incompensated networks there is a dedicated stage I0INT> 67NI.) Whenstarting happens often enough, such intermittent faults can be clearedusing the intermittent time setting.

When a new start happens within the set intermittent time, theoperation delay counter is not cleared between adjacent faults andfinally the stage will trip.

Four independent undirectional earth fault overcurrent stages

There are four separately adjustable earth fault stages: I0>, I0>>,I0>>>, and I0>>>>. The first stage I0> can be configured for definitetime (DT) or inverse time operation characteristic (IDMT). The otherstages have definite time operation characteristic. By using thedefinite delay type and setting the delay to its minimum, aninstantaneous (ANSI 50N) operation is obtained.

Inverse operation time (I0> stage only)

Inverse delay means that the operation time depends on the amountthe measured current exceeds the pick-up setting. The bigger thefault current is the faster will be the operation. Accomplished inversedelays are available for the I0> stage. The inverse delay types aredescribed in Chapter 5.17 Inverse time operation. The device willshow a scaleable graph of the configured delay on the local paneldisplay.

Inverse time limitation

The maximum measured secondary residual current is 10 x I0N andmaximum measured phase current is 50 x IN. This limits the scopeof inverse curves with high pick-up settings. See Chapter5.17 Inversetime operation for more information.

5.10.1 Earth fault faulty phase detection algorithmPhase recognition:

A zero sequence overcurrent has been detected.

Faulted phase/ phases are detected in 2 stage system.

1. Algorithm is using delta principle to detect the faulty phase/phases.

2. Algorithm confirms the faulty phase with neutral current anglecomparison to the suspected faulted phase.

Ideal grounded network:

When there is forward earth fault in phase L1, its current will increasecreating calculated or measured zero sequence current in phaseangle of 0 degrees. If there is reverse earth fault in phase L1, itscurrent will degrease creating calculated or measured zero sequencecurrent in phase angle of 180 degrees.

When there is forward earth fault in phase L2, its current will increasecreating calculated or measured zero sequence current in phaseangle of -120 degrees. If there is reverse earth fault in phase L2, itscurrent will degrease creating calculated or measured zero sequencecurrent in phase angle of 60 degrees.

77V265M/en M/A005


When there is forward earth fault in phase L3, its current will increasecreating calculated or measured zero sequence current in phaseangle of 120 degrees. If there is reverse earth fault in phase L3 itscurrent will degrease creating calculated or measured zero sequencecurrent in phase angle of -60 degrees.

Implementation:

When faulty phase is recognized, it will be recorded in 50N protectionfault log (also in event list and alarm screen). This faulted phase anddirection recording function has a tick box for enabling/disabling inprotection stage settings. For compensated network, this is not a100% reliable algorithm because it depends on the networkcompensation degree. So for compensated networks this featurecan be turned off so it will not cause confusion. For high impedanceearthed networks, there will be drop down menu in both settinggroups to choose between RES/CAP. RES is default and it is forearthed networks.When CAP is chosen, the Io angle will be correctedto inductive direction 90 degrees and after that faulty phase detectionis made.

Possible outcomes and conditions for those detections:

• FWD L1Phase L1 increases above the set limit and two other phasesremain inside the set (delta) limit. Io current angle is +/- 60degrees from L1 phase angle.

• FDW L2Phase L2 increases above the set limit and two other phasesremain inside the set (delta) limit. Io current angle is +/- 60degrees from L2 phase angle.

• FDW L3Phase L3 increases above the set limit and two other phasesremain inside the set (delta) limit. Io current angle is +/- 60degrees from L3 phase angle.

• FWD L1-L2Phase L1 and L2 increase above the set limit and phase L3remains inside the set (delta) limit. Io current angle is betweenL1 and L2 phase angles.

• FWD L1-L2-L3All three phase currents increase above the set delta limit.

• REV 1 (any one phase)One phase decreases below the set delta limit and other twophases remain inside the delta limit.

• REV 2 (any two phase)Two phases decrease below the set delta limit and third phaseremains inside the delta limit.

• REV 3 (all three phases)All three phase currents decrease below the set delta limit.

Example of a behaviour of the thermal model

Figure 5.26 shows an example of the thermal model behaviour. Inthis example = 30 minutes, k = 1.06 and kΘ = 1 and the currenthas been zero for a long time and thus the initial temperature rise is0 %. At time = 50 minutes the current changes to 0.85 x IMOT andthe temperature rise starts to approach value (0.85/1.06)2 = 64 %according the time constant. At time = 300 min, the temperature isabout stable, and the current increases to 5 % over the maximumdefined by the rated current and the service factor k. The temperaturerise starts to approach value 110 %. At about 340 minutes thetemperature rise is 100 % and a trip follows.

Initial temperature rise after restart

When the device is switched on, an initial temperature rise of 70 %is used. Depending of the actual current, the calculated temperaturerise then starts to approach the final value.

Alarm function

The thermal overload stage is provided with a separately settablealarm function. When the alarm limit is reached the stage activatesits start signal.

5.14 Circuit breaker failure protection CBFP(50BF)The circuit breaker failure protection can be used to trip any upstreamcircuit breaker (CB), if the fault has not disappeared within a giventime after the initial trip command. A different output contact of thedevice must be used for this backup trip.

The operation of the circuit-breaker failure protection (CBFP) is basedon the supervision of the signal to the selected trip relay and the timethe fault remains on after the trip command.

If this time is longer than the operating time of the CBFP stage, theCBFP stage activates another output relay, which will remainactivated until the primary trip relay resets.

The CBFP stage is supervising all the protection stages using thesame selected trip relay, since it supervises the control signal of thisdevice. See Chapter 8.4 Output matrixTable 5.20: Parameters of the circuit breaker failure stage CBFP (50BF)

5.16 Arc fault protection (50ARC/50NARC)optional

NOTE: This protection function needs optional hardware in slot X6. Moredetails of the hardware can be found in Chapter 11.4 Optional twochannel arc protection card and Table 12.9).

Arc protection is used for fast arc protection. The function is basedon simultaneous light and current measurement. Special arc sensorsare used to measure the light of an arc.

Stages for arc faults

There are four separate stages for the various current inputs:

for phase-to-phase arc faults. Current inputs IL1, IL2, IL3are used.

ArcI>:

for phase-to-phase arc faults. Current inputs I’L1, I’L2,I’L3 are used.

ArcI’>:

for phase-to-earth arc faults. Current input I01 is used.ArcI01>:

for phase-to-earth arc faults. Current input I02 is used.ArcI02>:

Light channel selection

The light information source to the stages can be selected from thefollowing list.

• - : No sensor selected. The stage will not work.

• S1: Light sensor S1.

• S2: Light sensor S2.

• S1/S2: Either one of the light sensors S1 or S2.

• BI: Binary input of the arc card. 48 Vdc.

• S1/BI: Light sensor S1 or the binary input.

• S2/BI: Light sensor S2 or the binary input.

• S1/S2/BI: Light sensor S1 or S2 or the binary input.

Binary input

The binary input (BI) on the arc option card (see Chapter 11.4Optional two channel arc protection card) can be used to get thelight indication from another relay to build selective arc protectionsystems.

The BI signal can also be connected to any of the output relays, BO,indicators etc. offered by the output matrix (see Chapter 8.4 Outputmatrix). BI is a dry input for 48 Vdc signal from binary outputs ofother VAMP devices or dedicated arc protection devices by VAMP.

V265M/en M/A00590

5 Protection functions5.16 Arc fault protection (50ARC/50NARC) optional

Binary output

The binary output (BO) on the arc option card (see Chapter 11.4Optional two channel arc protection card) can be used to give thelight indication signal or any other signal or signals to another relay'sbinary input to build selective arc protection systems.

Selection of the BO connected signal(s) is done with the output matrix(see Chapter 8.4 Output matrix). BO is an internally wetted 48 Vdcsignal for BI of other VAMP relays or dedicated arc protection devicesby VAMP.

Delayed light indication signal

Relay output matrix has a delayed light indication output signal(Delayed Arc L>) available for building selective arc protectionsystems. Any light source combination and a delay can be configuredstarting from 0.01 s to 0.15 s. The resulting signal is available in theoutput matrix to be connected to BO, output relays etc.

Pick up scaling

The per unit (pu) values for pick up setting are based on the currenttransformer values.

1 pu = 1 x IN = rated phase current CT valueArcI>:

1 pu = 1 x I'N = rated phase current CT valueArcI'>:

1 pu = 1 x I01N = rated residual current CT value for inputI01.

5.17 Inverse time operationThe inverse time operation - i.e. inverse delay minimum time (IDMT)type of operation - is available for several protection functions. Thecommon principle, formulae and graphic representations of theavailable inverse delay types are described in this chapter.

Inverse delay means that the operation time depends on themeasured real time process values during a fault. For example withan overcurrent stage using inverse delay a bigger a fault currentgives faster operation. The alternative to inverse delay is definitedelay. With definite delay a preset time is used and the operationtime does not depend on the size of a fault.

Stage specific inverse delay

Some protection functions have their own specific type of inversedelay. Details of these dedicated inverse delays are described withthe appropriate protection function.

Operation modes

There are three operation modes to use the inverse timecharacteristics:

• Standard delaysUsing standard delay characteristics by selecting a curve family(IEC, IEEE, IEEE2, RI) and a delay type (Normal inverse, Veryinverse etc). See Chapter 5.17.1 Standard inverse delays IEC,IEEE, IEEE2, RI.

• Standard delay formulae with free parametersselecting a curve family (IEC, IEEE, IEEE2) and defining one'sown parameters for the selected delay formula. This mode isactivated by setting delay type to ‘Parameters’, and then editingthe delay function parameters A – E. See Chapter 5.17.2 Freeparameterization using IEC, IEEE and IEEE2 equations.

• Fully programmable inverse delay characteristicsBuilding the characteristics by setting 16 [current, time] points.The relay interpolates the values between given points with 2nddegree polynomials. This mode is activated by setting curvefamily to ‘PrgN’'. There are maximum three differentprogrammable curves available at the same time. Eachprogrammed curve can be used by any number of protectionstages. See Chapter 5.17.3 Programmable inverse time curves.

Local panel graph

The device will show a graph of the currently used inverse delay onthe local panel display. Up and down keys can be used for zooming.Also the delays at 20 x ISET, 4 x ISET and 2 x ISET are shown.

V265M/en M/A00594

5 Protection functions5.17 Inverse time operation

Inverse time setting error signal

If there are any errors in the inverse delay configuration theappropriate protection stage will use definite time delay.

There is a signal ‘Setting Error’ available in output matrix, whichindicates three different situations:

1. Settings are currently changed with VAMPSET or local panel,and there is temporarily an illegal combination ofcurve/delay/points. For example if previous settings were IEC/NIand then curve family is changed to IEEE, the setting error willactive, because there is no NI type available for IEEE curves.After changing valid delay type for IEEE mode (for example MI),the ‘Setting Error’ signal will release.

2. There are errors in formula parameters A – E, and the device isnot able to build the delay curve

3. There are errors in the programmable curve configuration andthe device is not able to interpolate values between the givenpoints.

Limitation

The maximum measured phase current is 50 x IN and the maximumdirectly measured earth fault current is 5 x I0N. This limits the scopeof inverse curves when the setting is more than 2.5 x IN (overcurrentstages and earth fault stages using I0Calc input) or 0.25 x I01N (earthfault stages using I01 input or I02 input). The IN and I01N and I02Ndepend on the order code (See Chapter 14 Order information). Thetable below gives the limit values in secondary amperes.

Example of limitation

CT = 750 / 5

IN = 577 A

CT0 = 100 / 1 (a cable CT for I0)

Secondary scaled IMOTSEC is now 3.85 A

For 5 A CT secondaries and 1 A residual current inputs VAMP relayVAMP 265-5D7AAA is used. It has 5 A phase current inputs and 1A residual inputs.

For overcurrent stage I> the table below gives 12.5 A. Thus themaximum setting for I> stage giving full inverse delay range is 12.5A / 3.85 A = 3.25 x IMOT.

For earth fault stage I0> and input I01 the table below gives 0.25 A.Thus the maximum setting for I0> stage giving full inverse delayrange is 0.25 A / 1 A = 0.25 pu. This equals a 25 A primary earthfault current.

95V265M/en M/A005

5.17 Inverse time operation5 Protection functions

When using input signal I0Calc the corresponding setting is 12.5 A /1 A = 12.5 pu. This equals a 9375 A of primary earth fault current.

5.17.1 Standard inverse delays IEC, IEEE, IEEE2, RIThe available standard inverse delays are divided in four categoriesIEC, IEEE, IEEE2 and RI called delay curve families. Each categoryof family contains a set of different delay types according the followingtable.


The inverse time setting error signal will be activated, if the delaycategory is changed and the old delay type doesn't exist in the newcategory. See Chapter 5.17 Inverse time operation for more details.

Limitations

IEEE2 inverse time operation

Before the year 1996 and ANSI standard C37.112 microprocessorrelays were using equations approximating the behaviour of variousinduction disc type relays. A quite popular approximation isEquation 5.5, which in VAMP relays is called IEEE2. Another namecould be IAC, because the old General Electric IAC relays have beenmodeled using the same equation.

There are four different delay types according Table 5.30. The oldelectromechanical induction disc relays have inverse delay for bothtrip and release operations. However, in VAMP relays only the triptime is inverse the release time being constant.

The operation delay depends on the measured value and otherparameters according Equation 5.5. Actually this equation can onlybe used to draw graphs or when the measured value I is constantduring the fault. A modified version is implemented in the relay forreal time usage.

5.17.3 Programmable inverse time curvesOnly with VAMPSET, requires rebooting.

The [current, time] curve points are programmed using VAMPSETPC program. There are some rules for defining the curve points:

• configuration must begin from the topmost line

• line order must be as follows: the smallest current (longestoperation time) on the top and the largest current (shortestoperation time) on the bottom

• all unused lines (on the bottom) should be filled with [1.00 0.00s]

6 Supporting functions

6.1 Event logEvent log is a buffer of event codes and time stamps including dateand time. For example each start-on, start-off, trip-on or trip-off ofany protection stage has a unique event number code. Such a codeand the corresponding time stamp is called an event.

Events are the major data for a SCADA system. SCADA systemsare reading events using any of the available communicationprotocols. Event log can also be scanned using the front panel orusing VAMPSET. With VAMPSET the events can be stored to a fileespecially in case the relay is not connected to any SCADA system.

Only the latest event can be read when using communicationprotocols or VAMPSET. Every reading increments the internal readpointer to the event buffer. (In case of communication interruptions,the latest event can be reread any number of times using anotherparameter.) On the local panel scanning the event buffer back andforth is possible.

Event enabling/masking

In case of an uninteresting event, it can be masked, which preventsthe particular event(s) to be written in the event buffer. As a defaultthere is room for 200 latest events in the buffer. Event buffer sizecan be modified from 50 to 2000.

Modification can be done in “Local panel conf” –menu.

Indication screen (popup screen) can also be enabled in this samemenu when VAMPSET –setting tool is used. The oldest one will beoverwritten, when a new event does occur. The shown resolution ofa time stamp is one millisecond, but the actual resolution dependsof the particular function creating the event. For example mostprotection stages create events with 5ms, 10 ms or 20 ms resolution.The absolute accuracy of all time stamps depends on the timesynchronizing of the relay. See Chapter 6.5 System clock andsynchronization for system clock synchronizing.

The normal procedure is to poll events from the device all the time.If this is not done then the event buffer could reach its limits. In suchcase the oldest event is deleted and the newest displayed with OVFcode in HMI.Table 6.1: Setting parameters for events

6.2 Disturbance recorderThe disturbance recorder can be used to record all the measuredsignals, that is, currents, voltage and the status information of digitalinputs (DI) and digital outputs (DO).

The digital inputs include also the arc protection signals S1, S2, BIand BO, if the optional arc protection is available.

Triggering the recorder

The recorder can be triggered by any start or trip signal from anyprotection stage or by a digital input. The triggering signal is selectedin the output matrix (vertical signal DR). The recording can also betriggered manually. All recordings are time stamped.

Reading recordings

The recordings can be uploaded, viewed and analysed with theVAMPSET program. The recording is in COMTRADE format. Thisalso means that other programs can be used to view and analysethe recordings made by the relay.

For more details, please see a separate VAMPSET manual.

Number of channels

At the maximum, there can be 12 recordings, and the maximumselection of channels in one recording 12 (limited in wave form) anddigital inputs reserve one channel (includes all the inputs). Also thedigital outputs reserve one channel (includes all the outputs). If digitalinputs and outputs are recorded, there will be still 10 channels leftfor analogue waveforms.

6.2.1 Running virtual comtrade filesVirtual comtrade files can be run with VAMP relays with the v.10.74software or a later version. Relay behaviour can be analysed byplaying the recorder data over and over again in the relay memory.

Steps of opening the VAMPSET setting tool:

1. Go to “Disturbance record” and select Open… (A).

2. Select the comtrade file from you hard disc or equivalent.VAMPSET is now ready to read the recording.

3. The virtual measurement has to be enabled (B) in order to sendrecord data to the relay (C).

4. Sending the file to the device’s memory takes a few seconds.Initiate playback of the file by pressing the Go! button (D). The“Change to control mode” button takes you back to the virtualmeasurement.

NOTE: The sample rate of the comtrade file has to be 32/cycle (625 microseconds when 50 Hz is used). The channel names have tocorrespond to the channel names in VAMP relays: IL1, IL2, IL3, I01,I02, U12, U23, UL1, UL2, UL3 and U0.

6.4 Circuit breaker condition monitoringThe relay has a condition monitoring function that supervises thewearing of the circuit-breaker. The condition monitoring can givealarm for the need of CB maintenance well before the CB conditionis critical.

The CB wear function measures the breaking current of each CBpole separately and then estimates the wearing of the CB accordinglythe permissible cycle diagram. The breaking current is registeredwhen the trip relay supervised by the circuit breaker failure protection(CBFP) is activated. (See Chapter 5.14 Circuit breaker failureprotection CBFP (50BF) for CBFP and the setting parameter"CBrelay".)

Breaker curve and its approximation

The permissible cycle diagram is usually available in thedocumentation of the CB manufacturer (Figure 6.1). The diagramspecifies the permissible number of cycles for every level of thebreaking current. This diagram is parameterised to the conditionmonitoring function with maximum eight [current, cycles] points. SeeTable 6.6. If less than eight points needed, the unused points areset to [IBIG, 1], where IBIG is more than the maximum breakingcapacity.

If the CB wearing characteristics or part of it is a straight line on alog/log graph, the two end points are enough to define that part ofthe characteristics. This is because the relay is using logarithmicinterpolation for any current values falling in between the givencurrent points 2 – 8.

The points 4 – 8 are not needed for the CB in Figure 6.1. Thus theyare set to 100 kA and one operation in the table to be discarded bythe algorithm.

Setting alarm points

There are two alarm points available having two setting parameterseach.

• CurrentThe first alarm can be set for example to nominal current of theCB or any application typical current. The second alarm can beset for example according a typical fault current.

• Operations left alarm limitAn alarm is activated when there are less operation left at thegiven current level than this limit.

Any actual interrupted current will be logarithmically weighted for thetwo given alarm current levels and the number of operations left atthe alarm points is decreased accordingly. When the "operationsleft" i.e. the number of remaining operations, goes under the givenalarm limit, an alarm signal is issued to the output matrix. Also anevent is generated depending on the event enabling.

Clearing "operations left" counters

After the breaker curve table is filled and the alarm currents aredefined, the wearing function can be initialised by clearing thedecreasing operation counters with parameter "Clear" (Clear oper.left cntrs). After clearing the relay will show the maximum allowedoperations for the defined alarm current levels.

Operation counters to monitor the wearing

The operations left can be read from the counters "Al1Ln" (Alarm 1)and "Al2Ln" (Alarm2). There are three values for both alarms, onefor each phase. The smallest of three is supervised by the two alarmfunctions.

Thus the maximum number of current breaking at 6 kA is 945. Thiscan be verified with the original breaker curve in Figure 6.1. Indeed,the figure shows that at 6 kA the operation count is between 900and 1000. A useful alarm level for operation-left, could be in thiscase for example 50 being about five per cent of the maximum.

Example of operation counter decrementing when the CB isbreaking a current

Alarm2 is set to 6 kA. CBFP is supervising trip relay T1 and trip signalof an overcurrent stage detecting a two phase fault is connected tothis trip relay T1. The interrupted phase currents are 12.5 kA, 12.5kA and 1.5 kA. How many are Alarm2 counters decremented?

6.5 System clock and synchronizationThe internal clock of the relay is used to time stamp events anddisturbance recordings.

The system clock should be externally synchronised to getcomparable event time stamps for all the relays in the system.

The synchronizing is based on the difference of the internal time andthe synchronising message or pulse. This deviation is filtered andthe internal time is corrected softly towards a zero deviation.

Time zone offsets

Time zone offset (or bias) can be provided to adjust the local timefor IED. The Offset can be set as a Positive (+) or Negative (-) valuewithin a range of -15.00 to +15.00 hours and a resolution of 0.01/h.Basically quarter hour resolution is enough.

Daylight saving time (DST)

IED provides automatic daylight saving adjustments when configured.A daylight savings time (summer time) adjustment can be configuredseparately and in addition to a time zone offset.

Daylight time standards vary widely throughout the world. Traditionaldaylight/summer time is configured as one (1) hour positive bias.The new US/Canada DST standard, adopted in the spring of 2007is: one (1) hour positive bias, starting at 2:00am on the secondSunday in March, and ending at 2:00am on the first Sunday inNovember. In the European Union, daylight change times are definedrelative to the UTC time of day instead of local time of day (as inU.S.) European customers, please carefully find out local countryrules for DST.

V265M/en M/A005122

6 Supporting functions6.5 System clock and synchronization

The daylight saving rules for Finland are the IED defaults (24-hourclock):

- Daylight saving time start: Last Sunday of March at 03.00

- Daylight saving time end: Last Sunday of October at 04.00

To ensure proper hands-free year-around operation, automaticdaylight time adjustments must be configured using the “EnableDST” and not with the time zone offset option.

Adapting auto adjust

During tens of hours of synchronizing the device will learn its averagedeviation and starts to make small corrections by itself. The targetis that when the next synchronizing message is received, thedeviation is already near zero. Parameters "AAIntv" and "AvDrft" willshow the adapted correction time interval of this ±1 ms auto-adjustfunction.

Time drift correction without external sync

If any external synchronizing source is not available and the systemclock has a known steady drift, it is possible to roughly correct theclock deviation by editing the parameters "AAIntv" and "AvDrft". Thefollowing equation can be used if the previous "AAIntv" value hasbeen zero.

WeekDriftInOneAAIntv

8.604=

If the auto-adjust interval "AAIntv" has not been zero, but furthertrimming is still needed, the following equation can be used tocalculate a new auto-adjust interval.

used. For example if the drift has been 37 seconds in 14 days, therelative drift is 37*1000/(14*24*3600) = 0.0306 ms/s.

With these parameter values the system clock corrects itself with –1ms every 9.9 seconds which equals –61.091 s/week.

When the internal time is roughly correct – deviation is less than fourseconds – any synchronizing or auto-adjust will never turn the clockbackwards. Instead, in case the clock is leading, it is softly sloweddown to maintain causality.

125V265M/en M/A005


Synchronisation with DI

Clock can be synchronized by reading minute pulses from digitalinputs, virtual inputs or virtual outputs. Sync source is selected withSyncDI setting. When rising edge is detected from the selected input,system clock is adjusted to the nearest minute. Length of digital inputpulse should be at least 50 ms. Delay of the selected digital inputshould be set to zero.

Synchronisation correction

If the sync source has a known offset delay, it can be compensatedwith SyOS setting. This is useful for compensating hardware delaysor transfer delays of communication protocols. A positive value willcompensate a lagging external sync and communication delays. Anegative value will compensate any leading offset of the externalsynch source.

Sync source

When the device receives new sync message, the sync sourcedisplay is updated. If no new sync messages are received withinnext 1.5 minutes, the device will change to internal sync mode.

Sync source: IRIG-B003

IRIG-B003 synchronization is supported with a dedicatedcommunication option with either a two-pole or two pins in a D9 rearconnector (See Chapter 14 Order information).

IRIG-B003 input clock signal voltage level is TLL. The input clocksignal originated in the GPS receiver must be taken to multiple relaystrough an IRIG-B distribution module. This module acts as acentralized unit for a point-to-multiple point connection. Note: Daisychain connection of IRIG-B signal inputs in multiple relays must beavoided.

6.7 TimersThe VAMP protection platform includes four settable timers that canbe used together with the user's programmable logic or to controlsetting groups and other applications that require actions based oncalendar time. Each timer has its own settings. The selected on-timeand off-time is set and then the activation of the timer can be set tobe as daily or according the day of week (See the setting parametersfor details). The timer outputs are available for logic functions andfor the block and output matrix.

Figure 6.2: Timer output sequence in different modes.

The user can force any timer, which is in use, on or off. The forcingis done by writing a new status value. No forcing flag is needed asin forcing i.e. the output relays.

The forced time is valid until the next forcing or until the next reversingtimed act from the timer itself.

The status of each timer is stored in non-volatile memory when theauxiliary power is switched off. At start up, the status of each timeris recovered.

6.9 Self-supervisionThe functions of the microcontroller and the associated circuitry, aswell as the program execution are supervised bymeans of a separatewatchdog circuit. Besides supervising the relay, the watchdog circuitattempts to restart the micro controller in an inoperable situation. Ifthe micro controller does not resart, the watchdog issues aself-supervision signal indicating a permanent internal condition.

When the watchdog circuit detects a permanent fault, it always blocksany control of other output relays (except for the self-supervisionoutput relay). In addition, the internal supply voltages are supervised.Should the auxiliary supply of the IED disappear, an indication isautomatically given because the IED status inoperative (SF) outputrelay functions on a working current principle. This means that theSF relay is energized when the auxiliary supply is on and the arcflash protection is healthy.

6.9.1 DiagnosticsThe device runs self-diagnostic tests for hardware and software inboot sequence and also performs runtime checking.

Permanent inoperative state

If permanent inoperative state has been detected, the device releasesSF relay contact and status LED is set on. Local panel will alsodisplay a detected fault message. Permanet inoperative state isentered when the device is not able to handle main functions.

Temporal inoperative state

When self-diagnostic function detects a temporal inoperative state,Selfdiag matrix signal is set and an event (E56) is generated. In casethe inoperative state was only temporary, an off event is generated(E57). Self diagnostic state can be reset via local HMI.

Diagnostic registers

There are four 16-bit diagnostic registers which are readable throughremote protocols. The following table shows the meaning of eachdiagnostic register and their bits.

8 Control functions8.3 Virtual inputs and outputs

8.4 Output matrixBy means of the output matrix, the output signals of the variousprotection stages, digital inputs, logic outputs and other internalsignals can be connected to the output relays, front panel indicators,virtual outputs etc.

There are two LED indicators named "Alarm" and "Trip" on the frontpanel. Furthermore there are three general purpose LED indicators- "A", "B" and "C" - available for customer-specific indications. Inaddition, the triggering of the disturbance recorder (DR) and virtualoutputs are configurable in the output matrix. See an example inFigure 8.1.

An output relay or indicator LED can be configured as latched ornon-latched. A non-latched relay follows the controlling signal. Alatched relay remains activated although the controlling signalreleases.

There is a common "release latched" signal to release all the latchedrelays. This release signal resets all the latched output relays andindicators. The reset signal can be given via a digital input, via akeypad or through communication. Any digital input can be used forresetting. The selection of the input is done with the VAMPSETsoftware under the menu "Release output matrix latches". Under thesame menu, the "Release latches" parameter can be used forresetting.

8.6 Controllable objectsThe device allows controlling of six objects, that is, circuit-breakers,disconnectors and grounding switches. Controlling can be done by"select-execute" or "direct control" principle.

The object block matrix and logic functions can be used to configureinterlocking for a safe controlling before the output pulse is issued.The objects 1 – 6 are controllable while the objects 7 – 8 are onlyable to show the status.

Controlling is possible by the following ways:

• through the local HMI

• through a remote communication

• through a digital input

The connection of an object to specific output relays is done via anoutput matrix (object 1 – 6 open output, object 1 – 6 close output).There is also an output signal “Object failed”, which is activated ifthe control of an object is not completed.

Object states

Each object has the following states:DescriptionValueSetting

If changing states takes longer than the time defined by “Max ctrlpulse length” setting, object is inoperative and “Object failure” matrixsignal is set. Also undefined-event is generated. “Completion timeout”is only used for the ready indication. If “DI for ‘obj ready’” is not set,completion timeout has no meaning.

If changing states takes longer than the time defined by “Objecttimeout” setting, and “Object failure” matrix signal is set. Alsoundefined-event is generated.

8.6.1 Controlling with DIObjects can be controlled with digital input, virtual input or virtualoutput. There are four settings for each controllable object:

ActiveSetting

In remote stateDI for remote open / close control

In local stateDI for local open / close control

If the device is in local control state, the remote control inputs areignored and vice versa. Object is controlled when a rising edge isdetected from the selected input. Length of digital input pulse shouldbe at least 60 ms.

8.6.2 Local/Remote selectionIn Local mode, the output relays can be controlled via a local HMI,but they cannot be controlled via a remote serial communicationinterface.

In Remote mode, the output relays cannot be controlled via a localHMI, but they can be controlled via a remote serial communicationinterface.

The selection of the Local/Remote mode is done by using a localHMI, or via one selectable digital input. The digital input is normallyused to change a whole station to a local or remote mode. Theselection of the L/R digital input is done in the “Objects” menu of theVAMPSET software.

NOTE: A password is not required for a remote control operation.

9.1.1 Local port X4The local port has two connectors:

• On the front panel

• X4 the rear panel (D9S pins 2, 3 and 5)

Only one can be used at a time.

NOTE: The extension port is locating in the same X4 connector.

When the VX003 cable is inserted to the front panel connector itactivates the front panel port and disables the rear panel local portby connecting the DTR pin 6 and DSR pin 4 together. See Figure9.1.

Protocol for the local port

The front panel port is always using the command line protocol forVAMPSET regardless of the selected protocol for the rear panel localport.

If other than "None" protocol is selected for the rear panel local port,the front panel connector, when activated, is still using the plaincommand line interface with the original speed, parity etc. Forexample if the rear panel local port is used for remote VAMPSETcommunication using SPA-bus default 9600/7E1, it is possible totemporarily connect a PCwith VAMPSET to the front panel connectorwith the default 38400/8N1. While the front panel connector is inuse, the rear panel local port is disabled. The communicationparameter display on the local display will show the active parametervalues for the local port.

Physical interface

The physical interface of this port is RS-232.

9.2 Communication protocolsThe protocols enable the transfer of the following type of data:

• events

• status information

• measurements

• control commands.

• clock synchronizing

• Settings (SPA-bus and embedded SPA-bus only)

9.2.1 PC communicationPC communication is using a VAMP specified command lineinterface. The VAMPSET program can communicate using the localRS-232 port or using ethernet interface.

It is also possible to select SPA-bus protocol for the local port andconfigure the VAMPSET to embed the command line interface insideSPA-bus messages.

9.2 Communication protocols9 Communication

9.2.3 Profibus DPThe Profibus DP protocol is widely used in industry. An external VPA3CG is required.

Device profile "continuous mode"

In this mode, the device is sending a configured set of dataparameters continuously to the Profibus DP master. The benefit ofthis mode is the speed and easy access to the data in the Profibusmaster. The drawback is the maximum buffer size of 128 bytes,which limits the number of data items transferred to the master. SomePLCs have their own limitation for the Profibus buffer size, whichmay further limit the number of transferred data items.

Device profile "Request mode"

Using the request mode it is possible to read all the available datafrom the VAMP device and still use only a very short buffer forProfibus data transfer. The drawback is the slower overall speed ofthe data transfer and the need of increased data processing at theProfibus master as every data item must be separately requestedby the master.

NOTE: In request mode, it is not possible to read continuously only onesingle data item. At least two different data items must be read inturn to get updated data from the device.

There is a separate manual for VPA 3CG (VVPA3CG/EN M/xxxx)for the continuous mode and request mode. The manual is availableto download from our website.

Available data

VAMPSETwill show the list of all available data items for both modes.A separate document “Profibus parameters.pdf” is also available.

The Profibus DP communication is activated usually for remote portvia a menu selection with parameter "Protocol". See Chapter 9.1Communication ports.

9.2.5 IEC 60870-5-103The IEC standard 60870-5-103 "Companion standard for theinformative interface of protection equipment" provides standardizedcommunication interface to a primary system (master system).

The unbalanced transmission mode of the protocol is used, and thedevice functions as a secondary station (slave) in the communication.Data is transferred to the primary system using "data acquisition bypolling"-principle.

The IEC functionality includes application functions:

• station initialization

• general interrogation

• clock synchronization and

• command transmission.

It is not possible to transfer parameter data or disturbance recordingsvia the IEC 103 protocol interface.

The following ASDU (Application Service Data Unit) types will beused in communication from the device:

• ASDU 1: time tagged message

• ASDU 3: Measurands I

• ASDU 5: Identification message

• ASDU 6: Time synchronization and

• ASDU 8: Termination of general interrogation.

The device will accept:

• ASDU 6: Time synchronization

• ASDU 7: Initiation of general interrogation and

• ASDU 20: General command.

The data in a message frame is identified by:

• type identification

• function type and

• information number.

These are fixed for data items in the compatible range of the protocol,for example, the trip of I> function is identified by: type identification= 1, function type = 160 and information number = 90. "Private range"function types are used for such data items, which are not definedby the standard (e.g. the status of the digital inputs and the controlof the objects).

165V265M/en M/A005


The function type and information number used in private rangemessages is configurable. This enables flexible interfacing to differentmaster systems.

10 Applications

10.1 Restricted earth fault protectionRestricted earth fault (REF) protection is a sensitive way to protecta zone between two measuring points against earth faults. SeeFigure 10.1.

Figure 10.1: Principle of restricted earth fault protection. The CT secondaries arewired to cancel each other's currents during through faults and to drive all to therelay when the fault is inside the protected zone. (Saturation of the CTs makesthe situation a little more complicated than that.) The stabilizing resistor RSguarantees that the relay will not trip during a through fault. The VDR is used toprotect the CTs and the wiring by limiting the voltage VS during heavy inside faults.

When there is a fault outside the protected zone the CT secondarieswill cancel each other's currents. This is partly true even if both oronly one of the CTs saturates, because the impedance of a saturatedCT secondary will collapse to near zero. The non-zero wiringimpedance and CT impedance will however cause a voltage VS, butthe resistor RS will prevent the relay from tripping. RS is called thestabilizing resistor.

During an inside fault the secondary currents of the two CTs haveno other way to go than the relay. The relay will trip when the currentI = VS / RS exceeds the setting IS of the relay. The voltage dependentresistor (VDR, varistor, METROSIL) is used to protect the CTs andwiring by limiting the voltage VS during heavy inside faults.

The resistance of the secondary loop connecting the CTs togethershould be as low as possible.

173V265M/en M/A005

10.2 Restricted earth fault protection for a transformer with neutralconnection

10 Applications

10.2.1 CT RequirementsAny difference between the CTs will give a misleading residualcurrent signal to the relay. Especially during heavy through faults(i.e. the fault is outside the protected zone) the dissimilar saturationof the CTs should not yield to a REF trip. On the other hand a veryhigh fault current causing an unselective earth fault start or trip isnot a fatal error.

Class X CT

In restricted earth fault protection the high and low side CTs shouldgive similar responses even for high over currents.

Class X CTs will fulfil this requirement. Their performance is definedin terms of a knee-point voltage (VKP), the magnetizing current atthe knee point voltage and the resistance of the secondary windingat +75°C.

Knee point voltage (VKP) is the secondary voltage at which a 50 %increase of primary current is needed to increase the secondaryvoltage by 10 %.

10 Applications

10.3.2 Voltage limitDuring heavy inside faults the voltage in the secondary circuit mayrise to several kilovolts depending on the fault currents, CT propertiesand the stabilizing resistor RS. If the secondary voltage would exceed2 kV it should be limited using a voltage dependent resistor (VDR).

10.4 Current Transformer SelectionIron core current transformers (CT) are accurate in amplitude andphase when used near their nominal values. At very low and at veryhigh currents they are far from ideal. For over-current and differentialprotection, the actual performance of CTs at high currents must bechecked to ensure correct function of the protection relay.

NOTE: All current based protection functions of VAMP relays, except arcprotection, thermal protection and 2nd harmonic blocking functions,are using the fundamental frequency component of the measuredcurrent. The IEC formula includes an RMS value of the current. Thatis why the composite error defined by IEC 60044-1 is not ideal forVAMP relays. However the difference is not big enough to preventrough estimation.

10.4.2 CT Requirement for ProtectionWhen the through current equals and exceeds kA x IN there may beenough secondary differential current to trip a relay although thereis no in zone fault. This is because the CTs are unique and they donot behave equally when approaching saturation.

10.6 Trip circuit supervisionTrip circuit supervision is used to ensure that the wiring from theprotective device to a circuit-breaker is in order. This circuit is unusedmost of the time, but when a protection device detects a fault in thenetwork, it is too late to notice that the circuit-breaker cannot betripped because of a broken trip circuitry.

The digital inputs of the device can be used for trip circuit monitoring.The dry digital inputs are most suitable for trip circuit supervision.The first six digital inputs of VAMP 200 series relays are not dry andan auxiliary miniature relay is needed, if these inputs are used fortrip circuit supervision.

Also the closing circuit can be supervised, using the same principle.

In many applications the optimum digital inputs for trip circuitsupervision are the optional inputs DI19 and DI20. They don't sharetheir terminals with any other digital inputs.

10.6.1 Trip circuit supervision with one digital inputThe benefits of this scheme is that only one digital inputs is neededand no extra wiring from the relay to the circuit breaker (CB) isneeded. Also supervising a 24 Vdc trip circuit is possible.

The drawback is that an external resistor is needed to supervise thetrip circuit on both CB positions. If supervising during the closedposition only is enough, the resistor is not needed.

• The digital input is connected parallel with the trip contacts(Figure 10.6).

• The digital input is configured as Normal Closed (NC).

• The digital input delay is configured longer than maximum faulttime to inhibit any superfluous trip circuit fault alarm when thetrip contact is closed.

• The digital input is connected to a relay in the output matrix givingout any trip circuit alarm.

• The trip relay should be configured as non-latched. Otherwise,a superfluous trip circuit fault alarm will follow after the trip contactoperates, and the relay remains closed because of latching.

• By utilizing an auxiliary contact of the CB for the external resistor,also the auxiliary contact in the trip circuit can be supervised.

• When using the dry digital inputs DI7 –, using the other inputsof the same group, sharing a common terminal, is limited.

• When using the wet digital inputs DI1 – DI6, an auxiliary relay isneeded.

A 0.5 W resistor will be enough for this short time peak power, too.However, if the trip relay is closed for longer time than a few seconds,a 1 W resistor should be used.

Using any of the non-dry digital inputs DI1 – DI6

In this scheme an auxiliary relay is needed to connect the wet digitalinput to the trip circuit (Figure 10.12). The rated coil voltage of theauxiliary relay is selected according the rated auxiliary voltage usedin the trip circuit. The operating voltage range of the relay should beas wide as possible to cover the tolerance of the auxiliary voltage.

In this application using the other wet inputs for other purposes isnot limited unlike, when using the dry inputs.

P = 121^2 / 1500 = 9.8 W

A 1 W resistor should be selected to withstand this short time peakpower. However, if the trip relay can be closed for longer time thana few seconds, a 20 W resistor should be used.

10.6.2 Trip circuit supervision with DI19 and DI20The benefits of this scheme is that no external resistor is needed.

The drawbacks are, that two digital inputs from two separate groupsare needed and two extra wires from the relay to the CB compartmentis needed. Additionally the minimum allowed auxiliary voltage is 48Vdc, which is more than twice the threshold voltage of the dry digitalinput, because when the CB is in open position, the two digital inputsare in series.

• The first digital input is connected parallel with the auxiliarycontact of the open coil of the circuit breaker.

• Another auxiliary contact is connected in series with the circuitryof the first digital input. This makes it possible to supervise alsothe auxiliary contact in the trip circuit.

• The second digital input is connected in parallel with the tripcontacts.

• Both inputs are configured as normal closed (NC).

• The user’s programmable logic is used to combine the digitalinput signals with an AND port. The delay is configured longerthan maximum fault time to inhibit any superfluous trip circuitfault alarm when the trip contact is closed.

• The output from the logic is connected to a relay in the outputmatrix giving out any trip circuit alarm.

V265M/en M/A005194


• The trip relay should be configured as non-latched. Otherwise,a superfluous trip circuit fault alarm will follow after the trip contactoperates, and the relay remains closed because of latching.

• Both digital inputs must have their own common potential.Using the other digital inputs in the same group as the upper DIin the Figure 10.15 is not possible in most applications. Usingthe other digital inputs in the same group as the lower DI in theFigure 10.15 is limited, because the whole group will be tied tothe auxiliary voltage VAUX.

NOTE: In many applications the optimum digital inputs for trip circuitsupervision are the optional inputs DI19 and DI20 because they don'tshare their terminals with any other digital inputs.

Binary output (BO)X6: 2

Common for BI and BO.X6: 3

Sensor 1X6: 4-5

Sensor 2X6: 6-7

The binary output of the arc option card may be activated by the arcsensors or by any available signal in the output matrix. The binaryoutput can be connected to an arc binary input of another VAMPprotection device.

11.5 Optional digital I/O card (DI19/DI20)NOTE: When this option card is installed, the parameter "Arc card type" has

value "Arc+2DI". With DI19/DI20 option only one arc sensor channelis available. Please check the ordering code in Chapter 14 Orderinformation.

If the slot X6 is already occupied with the two channel arc sensorcard (Chapter 11.4 Optional two channel arc protection card), thisoption is not available.

The DI19/DI20 option enables two more digital inputs. These inputsare useful in applications where the contact signals are not potentialfree. For example trip circuit supervision is such application. Theinputs are connected to terminals X6:1 – X6:2 and X6:3 – X6:4.
