3 Protection functions

3.1 Arc flash protection

3.1.1 Arc flash protection, general principleThe arc flash protection contains 8 arc stages, which may be usedto trip e.g. the circuit breakers. Arc stages are activated withovercurrent and light signals (or light signal alone). The allocation ofdifferent current and light signals to arc stages is defined in arc flashprotection matrices: current, light and output matrix. The matricesare programmed via the arc flash protection menus.

3.1.2 Arc flash protection menusThe arc flash protection menus are located in the main menu underARC. The ARC menu can be viewed either on the local HMI, or byusing VAMPSET.

Matrix correlation principle

When determining the activating conditions for a certain arc stage,a logical AND is made between the outputs from the arc light matrixand arc current matrix.

If an arc stage has selections in only one of the matrixes, the stageoperates on light-only or on current-only principle.

4.1 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.

As an example of information included with a typical event aprogrammable stage trip event is shown in the following table.

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 an otherparameter.) 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 10 ms or 20 ms resolution. Theabsolute accuracy of all time stamps depends on the time

Event buffer overflow

The normal procedure is to poll events from the device all the time.If this is not done, the event buffer will eventually overflow. On thelocal screen this is indicated with string "OVF" after the event code.Table 4.1: Setting parameters for events

4.2 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.

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. Thismeans that also 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 is also 12 (limited in waveformrecording). The digital inputs reserve one channel (includes all theinputs). Also the digital outputs reserve one channel (includes all theoutputs). If digital inputs and outputs are recorded, there will be still10 channels left for analogue waveforms.Table 4.2: Disturbance recorder parameters

Running virtual comtrade files

Virtual comtrade files can be run with the device. Device behaviourcan be analysed by playing the recorder data over and over againin the relay memory.

NOTE: This is not applicable to the arc protection functions of thedevice.

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 (625micro seconds when 50 Hz is used). The channel nameshave to correspond to the channel names in Vamp relays:IL1, IL2, IL3, Io1, Io2, U12, U23, UL1, UL2, UL3 and Uo.

VAMP 3214 Supporting functions4.2 Disturbance recorder

4.3 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.

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.

The term DriftInOneWeek/604.8 may be replaced with the relativedrift multiplied by 1000, if some other period than one week has beenused. For example if the drift has been 37 seconds in 14 days, therelative drift is 37*1000/(14*24*3600) = 0.0306 ms/s.

Example 1

If there has been no external sync and the relay's clock is leadingsixty-one seconds a week and the parameter AAIntv has been zero,the parameters are set as

***) Set the DI delay to its minimum and the polarity such that the leading edge is thesynchronizing edge.

****) Relay needs to be equipped with an IRIG-B option module to receive clock syncroniz-ation signal (Chapter 16 Order information).

Synchronisation with DI

Clock can be synchronized by reading minute pulses from digitalinputs, virtual inputs or virtual outputs. Sync source is selected withMinute sync pulse DI setting.

When rising edge is detected from the selected input, system clockis adjusted to the nearest minute. Length of digital input pulse shouldbe at least 50 ms. Delay of the selected digital input should be setto zero.

41V321/en M/B005

4.3 System clock andsynchronization


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.

Deviation

The time deviation means how much system clock time differs fromsync source time. Time deviation is calculated after receiving newsync message. The filtered deviation means how much the systemclock was really adjusted. Filtering takes care of small deviation insync messages.

Auto-lag/lead

The device synchronizes to the sync source, meaning it startsautomatically leading or lagging to stay in perfect sync with themaster. The learning process takes few days.

4.4 Non-volatile RAMThe non-volatile RAM of the device is implemented using a supercapacitor and a RAM memory with low power consumption.

When auxiliary power is on the super capacitor is charged from theinternal power supply of the device and the non-volatile RAMmemoryalso gets power from the same source. When auxiliary power isturned off the RAM memory is powered by the super capacitor. Thememory will keep its contents as long as there is enough voltage inthe super capacitor. This time is 7 days in +25C room temperature– high humidity will decrease the time.

The non-volative RAM is used to store the disturbance recordingsand the event-buffer.

V321/en M/B00542

VAMP 3214 Supporting functions4.4 Non-volatile RAM

4.5 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 a inoperable situation. Ifthe restarting fails, the watchdog issues a self-supervision signalindicating 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 and the output relays used in the arc protection funcion).

The condition of the VAMP 321 central unit, the I/O units and thesensors are supervised. Events are generated when possibleproblems occur or disappear. The events are stored in the IED eventbuffer and they can be read on the local HMI or VAMPSET.

Channel, events codes and situations where events are generated:

Only some of the communication protocols (IEC 61850, SPA-bus,Modbus and ModbusTCP) have capability to transfer all of these

events. In some protocols only a selected subset can be trasferredor only status of COM5 is available with the help of logicprogramming.

4.5.1 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 also displaya detected fault message. Permanet inoperative state is enteredwhen 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 eachdagnostic register and their bits.

5 Measurement functions

5.1 Measurements for arc protectionfunctionThe three phase current measurement and earth-fault currentmeasurement for arc protection is done with electronics (see figure).The electronics compares the current levels to the pick-up settings- THRESHOLDs - and gives a binary signals “I>>” or “Io>>” to thearc protection function if limit is exceeded. All the frequencycomponents of the currents are taken into account.

Signals “I>>” or “Io>>” are connected to a FPGA chip whichimplements the arc protection function. The pick-up settings arenamed “I> int” and “Io> int” in the local LCD panel or VAMPSETviews, these settngs are used to set the THRESHOLD levels for theelectronics.

The accuracy of the arc protection measurements is as follows:

• Under nominal current: 5% of nominal

• Over nominal current: 5% of measured/injected value

5.11 Primary, secondary and per unit scalingMany measurement values are shown as primary values althoughthe relay is connected to secondary signals. Some measurementvalues are shown as relative values - per unit or per cent. Almost allpick-up setting values are using relative scaling.

The scaling is done using the given CT, VT values.

The following scaling equations are useful when doing secondarytesting.

5.11.1 Current scaling

NOTE: The rated value of the device's current input 5 A, does nothave any effect in the scaling equations, but it defines themeasurement range and the maximum allowed continuouscurrent.

An output relay can be configuredas latched or non-latched. The difference between trip contacts andsignal contacts is the DC breaking capacity. The contacts are normalopen type (NO), except signal relay A1 which has change overcontact (SPDT).Table 6.1: Parameters of output relays

6.2 Digital inputsDigital inputs are available for control purposes. The number ofavailable inputs depends on the number and type of I/O cards.

The polarity – normal open (NO) / normal closed (NC) – and a delaycan be configured according the application. The signals are availablefor the output matrix, block matrix, user's programmable logic etc.

The digital inputs need an external control voltage (ac or dc). Thevoltage nominal activation level can be selected in Chapter16 Orderinformation.

Nominal voltageSelection in order code

24 V dc / 110 V ac1

110 V dc / 220 V ac2

220 V dc3

When 110 or 220 V ac voltage is used to activate the digital Inputs,the AC mode should be selected as shown in the screenshot below:

Figure 6.1: AC mode selection in VAMPSET

These inputs are ideal for transferring the status information ofswitching devices into the device.

Label and description texts can be edited with VAMPSET accordingthe application. Labels are the short parameter names used on thelocal panel and descriptions are the longer names used byVAMPSET.

NOTE: The high-speed arc flash protection functions utilize binaryinput signals (BI) instead of the digital inputs (read more inchapter “Arc flash protection” and in chapter “Binary inputsand outputs”.)

Binary inputs

The binary inputs (BI) can be used to get the light indication fromanother IED to build selective arc protection systems. BI is a dryinput for 18…42 V dc signal. The connection of BI signals isconfigured in the matrices of the arc flash protection function.

Binary output

The binary outputs (BO) can be used to give the light indication signalor any other signal or signals to another IED's binary input to buildselective arc protection systems. BO is an internally wetted 30 Vdcsignal. The connection of BO signals is configured in the matricesof the arc flash protection function.

6.6 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, virtual outputs etc.

NOTE: For cofiguring the high-speed operations of the arc protectionthe “ARC MATRIX – OUTPUT” must be used.

There are general purpose LED indicators – "A", "B", "C",….”N” –available for customer-specific indications on the front panel. Theirusage is define in a separate LED MATRIX.

Furthermore there are two LED indicators specified for keys F1 andF2. In addition, the triggering of the disturbance recorder (DR) andvirtual outputs are configurable in the output matrix.

See an example in Figure 6.2.

Figure 6.2: Output matrix

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 with CPU control. The reset signal can be given via adigital input, via a keypad or through communication. Any digitalinput can be used for resetting. The selection of the input is donewith the VAMPSET software under the menu "Release output matrixlatches". Under the same menu, the "Release latches" parametercan be used for resetting. See an example in Figure 6.3.

NOTE: "Release latched" signal will not clear or reset FPGAcontrolled latches.

6.7 Blocking matrixBy means of a blocking matrix, the operation of any protection stage(except the arc protection stages) can be blocked. The blockingsignal can originate from the digital inputs or it can be a start or tripsignal from a protection stage or an output signal from the user'sprogrammable logic. In the block matrix Figure6.4, an active blockingis indicated with a black dot (•) in the crossing point of a blockingsignal and the signal to be blocked.

When the IED is power upthe “On” LED will lit as green. During normal use “Service” LED isnot active, it activates only when internal error occurs and the IEDis not operating correctly. When this happenes contact your localrepresentative for further guidance.

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

The logic functions can be used to configure interlocking for a safecontrolling before the output pulse is issued. The objects 1...6 arecontrollable while the objects 7...8 are only able to show the status.

Controlling is possible by the following ways:

• through the local HMI

• through a remote communication

• through a digital input

• through the function key

The connection of an object to specific output relays is done via anoutput matrix (object 1-6 open output, object 1-6 close output). Thereis also an output signal “Object failed”, which is activated if the controlof an object is not completed.

Object states

Each object has the following states:DescriptionValueSetting

The protocol is an ASCII character protocol called “GetSet”. Thespeed of the interface is defined in CONF/DEVICE SETUP menufrom the local HMI. The default settings for the relay are 38400/8N1.

Physical interface

The physical interface of this port is USB.

7.1.2 COM 1….COM 4 portsCOM 1…COM 4 are serial ports for communication with protocolslike IEC 103. The type of the physical interface on these portsdepends on the type of the selected communication option module.The use of some protocols may require a certain type of optionmodule for example ProfibusDP can only be used with externalprofibus module VPA 3CG, if the hardware interface of the COM portis RS-232.

7.2 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)

7.2.1 GetSetThis is and ASCII protocol used by VAMPSET. This protocol is theprotocol used on the USB port. This can also be used on the COMports, if VAMPSET interface via these ports is required.

7.2.2 Modbus TCP and Modbus RTUThese Modbus protocols are often used in power plants and inindustrial applications. The difference between these two protocolsis the media. Modbus TCP uses Ethernet and Modbus RTU usesasynchronous communication (RS-485, optic fibre, RS-232).

VAMPSET will show the list of all available data items for Modbus.A separate document “Modbus data.pdf“ is also available.

The Modbus communication is activated usually for remote port viaa menu selection with parameter "Protocol". See Chapter 7.1Communication ports .

7.2.3 Profibus DPThe Profibus DP protocol is widely used in industry. An external VPA3CG and VX072 cables are 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 onlyone single data item. At least two different data items mustbe read in turn 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.

7.2.5 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 the followingapplication functions:

• station initialization

• general interrogation

• clock synchronization and

• command transmission.

83V321/en M/B005


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).

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

VAMP 3218 Application example

Functional description

In this application example, the arc flash sensor for zone 1.1 isconnected to the I/O unit input number 1. If the arc flash sensorawakens and simultaneously VAMP 321 sends a current signal tothe I/O unit, the zone 1.1 is isolated by the outgoing feeder breaker.

The arc flash sensor for zone 1.2 is connected to the I/O unit inputnumber 2 or 3. If the arc flash sensor awakens and simultaneouslyVAMP 321 sends a current signal to the I/O unit, the zone 1.2 isisolated by the outgoing feeder breaker.

The arc flash sensors for zone 1 are connected to the I/O unit sensorchannels 4...10. If a sensor awakens in zone 1, the light-only signalis transferred to VAMP 321 which then trips the main circuit breaker.

NOTE: For 12L and 12LD units, three sensor channels can tripindependently their own zone, the other seven sensorchannels can be allocated to another zone.

The sensor S2 connected to VAMP 321 in zone B overlaps the zoneA. If the circuit breaker fails to isolate the failure in zone B, the sensor(S2) generates a time-delayed circuit-breaker failure protection tripto the upstream breaker.

The incoming feeder circuit breaker has a CBFP backup trip to theupstream breaker. If the zone 1 trip (T1) fails, the CBFP takes overand trips the upstream circuit breaker.

The zone A illustrates a typical medium voltage incoming feederwhere the current transformers are located after the cable termination.In this case, an eventual arc flash fault in the cable termination doesnot activate the current element in VAMP 321. However, arcprotection can be achieved by using the light-only principle. If an arcflash occurs in cable termination, the zone A is tripped by anupstream circuit breaker. The sensor S1 in zone A overlaps theincoming circuit breaker.

The zone A operates on light-only principle as the currents are notavailable for current and light operation.

The circuit-breaker failure protection (CBFP) protects in case thereis a failure in zone 1, or in sensor S2 in zone B. The trip output(T2/CBFP) can function as a trip output, but also as a time-delayedcircuit-breaker failure protection. To enable CBFP, an additionaltime-delayed stage needs to be created.

14 Commissioning and testing

The commissioning and testing procedure is introduced in separateTesting Manual type VARCTEST/EN M/xxxx. Study the testingdocument before executing commissioning or testing.

By default the over current setting is set to 1.2 xIN. Make sure thatthe over current setting is made in accordance to protection selectivitystudy to comply CT and other requirements.

During testing, pay attention and check that correct breakers trip inaccordance with the zone selection.

14.1 DecommissioningIn case the commissioned system requires decommissioning wheresystem components are changed or removed make sure that theswitchgear to be protected is turned off.

WARNINGDECOMMISSIONING OF ARC PROTECTION SYSTEM

Switch off the primary supply in case of decommissioning.

Failure to follow these instructions can result in death orserious injury

Make sure that the switchgear is restored back to it's originalconstruction if arc protection components are removed from the gear.Pay attention that possible holes, and cut-outs are not left in theswitchgear.

15 Maintenance

The Vamp 321 IED and its extension units require maintenance inorder to work according to specification. Keep record of themaintenance actions performed for the system. The maintenancecan include, but is not limited the following actions.

15.1 Preventative maintenanceThe Vamp 321 IED and it's extension units, sensor and cabling shallbe visually checked when the switchgear is de-energized. Duringsuch inspection pay attention to

• possible dirty arc sensors

• loose wire connections

• damaged wiring

• indicator lights ( see section LED test sequence) and

• other mechanical connections.

Visual inspection shall be made maximum every three (3) years.

15.2 Periodical testingThe IED and it's satellite extension units, cabling and sensors mustperiodically be tested according to the end-user's safety instructions,national safety instructions or law. Manufacturer recommendfunctional testing being carried minimum every five (5) years.

It is proposed that the periodic testing is conducted with a secondaryinjection principle for those protection stages which are used in theIED and it's extension units.

Follow separate testing manual (VARCTEST/EN/M_xxxx) for a testprotocol.

15.3 Cleaning of hardwareSpecial attention must be paid that the IED, it's extension units andsensors do not become dirty. In case cleaning is required wipe outdirt out from the units

15 MaintenanceVAMP 321

15.4 Sensor condition and positioning checkAfter commissioning, sensor replacement, modification procedure,cleaning and periodical testing always check that the sensorpositioning remain as it was originally designed.

15.5 System status messagesIn case IED's self checking detects unindented system status it willin most of the cases provide alarm concerning this by activating theService LED and indication status notification on the LCD screen.Should this happen store the possible message and contact yourlocal representative for further guidance.

15.6 Spare partsUse entire unit as a spare for the device to be replaced. Always storespare parts in storage meet requirements stated in sectionEnvironmental conditions.
