self-powered protection relaysThe VIP30 and VIP35 relays aredesigned for use in distributionnetworks, mainly in MV/LVsubstations in which they provideprotection for upstreamtransformers.They are self-powered relaysrequiring no external DC powersource or batteries, making them theideal solution for location in remoteareas or where auxiliary supplies arenot available.n The VIP30 provides protectionagainst phase-to-phase faults.n The VIP35 provides protectionagainst phase-to-phase faults andearth faults.

phase protectionPhase protection uses an IDMTsetting that operates at 1.2 times thesetting current (Is). Phase protectionon the VIP30 and VIP35 are thesame.

earth protectionProtection against earth faultsoperates by measurement ofresidual current based on the sum ofthe CT secondary currents.Measurement is carried out by aCSH30 core balance CT mounted onthe back of the VIP35 unit. Earthprotection operates with definitetime; the setting and time delay areadjustable.

Current transformersn CT’s 500/200/1The VIP30/35 relays must be usedwith the CT’s to obtain the specifiedcharacteristics.- The Current Transformers have 2ranges; according to the range used,the setting current is adjustable from8A to 80A or from 20A to 200A.- The cross-section of the core andthe resistance of the winding areadapted to protect the VIP30/35 inthe event of a short-circuit.

descriptionn The VIP30 and VIP35 relays aremounted in a polycarbonate injectedcasing which protects them againstdripping water and dust.

The front is protected by atransparent cover fitted with asealing joint. The cover may be lead-sealed to prohibit access to thesettings.n Rotating selector switches areused for setting. The phase settingcurrent and earth fault setting currentare set directly in amperes. Thismeans that the scale on the frontmust be adapted to suit the rangeused on the CT. This is done bypositioning a "setting scale label" onthe relay at the time oftesting/commissioning.n The connections are made on theback of the relay.

2. phase overcurrent setting (Is)Time-delayed tripping of the phaseprotection takes place at 1.2 x Is.According to the range used on theCT, the setting current is adjustablefrom 8A to 80A or from 20A to 200A;The scale label inserted shouldmatch the CT and range selected.

4. earth fault setting Io>The setting is made directly in MVamperes.

5. earth fault setting time delayThe earth fault protection time delayis set in seconds.

6. inrush current delayThis selector switch starts up theinrush current delay (1s). The timedelay prevents tripping by the earthprotection when the VIP35 isenergized during closing of thecircuit breaker. The time delay is onlyactive for the earth protection andhas no effect on tripping by thephase protection.n in off position:The inrush current delay is notactivated. The earth fault protectionoperates according to the setting ofthe selector switch (5).n in on: positionThe inrush current delay is activated.In this case:- when the VIP35 is energized, andthe circuit breaker closes, tripping bythe earth protection is delayed by 1second.- when the VIP35 has been suppliedfor more than a second, the earthprotection is time-delayed accordingto the setting (5).

F When the circuit breaker closes,energizing of the MV/LV transformermay generate aperiodic inrushcurrents with a DC component thatmomentarily saturates the magneticcores of the VIP35 CT’s. Because ofthis, each CT gives an erroneousresult and the sum of the phasecurrents (at the CT secondarywindings) is no longer zero. There isfalse earth fault detection that maycause tripping of the earth faultprotection.This is especially critical when thesetting and time delay settings arelow.

F If the time delay settings arebelow the values indicated in thechart below, start up the inrushcurrent delay:

Io> setting to> time delay0.8 to 0.9 x Ia 0.2 s0.6 to 0.8 x Ia 0.3 s0.4 to 0.6 x Ia 0.4 s0.2 to 0.4 x Ia 0.5 s

- how to insert label

a. setting scale labeln The label indicates the range forthe phase overcurrent and earth faultprimary amp settings. It is insertedfrom the top, behind the transparentpart of the front panel.The label is reversible and is printedwith the 200/1A range on one side,and the 500/1A range on the other.

b. current transformer used andwiringThe text is printed on the settingscale label. It indicates whichsecondary winding of the CurrentTransformer is to be used inaccordance with the chosen range.When the label is in position in theslot, the text is hidden by and opaquezone. It is not visible to the user.F also refer to the "CurrentTransformer and operating ranges"chapter.

c. VAP6 test plugThe test plug is exclusively designedfor connection of the VAP6 which isused for fast, simplified relay testing.The operation may be carried outwhile the relay is operating since theVAP6 and VIP30/35 provide thepossibility of testing with inhibition ofcircuit breaker tripping.

- testing of the VIP30/35 using theVAP6 -

d. minimum time delay switchn The circular opening on the frontfacia gives access to a switch whichis used to time delay the trippingorder by at least 25 ms. The timedelay may be started up to preventthe circuit breaker from breaking atthe beginning of the asymmetricalphase in the event of a strong fault.n It should or should not be startedup, depending on the type of circuitbreaker. The user does not haveaccess to the time delay since theopening is hidden by the settingscale label.


3. current transformers

Current transformers To obtain the performancesindicated, the VIP30 and VIP35 mustbe used with the currenttransformers supplied on theRingmaster range. The relay/CTassembly must be used together tocomply with the technicalcharacteristics indicated, inparticular:- operation across the range- tripping time- accuracy- short-circuit performanceIt is compulsory for the CT’s of eachof the phases to be of the same type.

- facia of the VAP6

The VAP6 is a portable unit which isconnected to the VIP30/35 to carryout simplified testing.The test can be carried out in thefollowing two cases:- the VIP30/35 is already powered upby the CT’s.- the VIP30/35 is not supplied by theCT’s. In this case, the VAP6 batteriessupply power to the relay.

The test consists of:- injecting a current to simulate aphase fault.- injecting a current to simulate anearth fault (VIP35).- checking tripping.Frefer to the description of the testin the section entitled "testsequence"F the VAP6 is supplied by batteries.Therefore the parts of the VIP30/35that run on AC current are notchecked using this method (inputand supply circuits).

push-buttonsn battery test: if the batteries arehealthy, the "on" indicator lights upwhen the button is pressed.n phase overcurrent: Sends thephase overcurrent test current, whichis equivalent to 20 times the settingcurrent Is.n earth fault: Sends the earth faulttest current. The current is equivalentto a current greater than the highestof the Io> settings.n trip inhibition: By pressing andholding this button down the relaycan be tested with the VAP6 withouttripping the circuit breaker. Thisfacility will inhibit the circuit breakertripping even if a real fault occursduring the test.

indicatorsn on: indicates that the batteries areoperating. Also lights up when thebattery test is carried out by pressing"battery test".n test in progress: confirmssending of the test current to theVIP30/35.n trip: it lights up when the VIP30/35sends a tripping order (whether ornot the circuit breaker is inhibited).

"external mitop" outputThis feature may be used to connectan external MITOP trip coil whichcould be used to operate a timer etc.The external coil is triggered at thesame time as the circuit breakerMITOP. The trip inhibit button doesnot affect the external coil.

batteriesn the batteries are normallydeactivated and are automaticallyactivated when the VAP6 isconnected to the VIP30/35.They are activated in the followingcases:- pressing the "battery test" button.- direct connection to the VIP30/35.

n to install or change the batteries,open the unit by removing the 4screws on the bottom of the unit. Besure to use the correct polarities.

8. Commissioning Ringmaster with VIP 30/35

Factory tests:

All Ringmaster panel types are fullytested before leaving the factory.These tests include the wholeprotection system including currenttransformers, wiring harness, relay,trip coil and the circuit breaker itselfusing primary injection to energisethe system.Tripping tests are carried out usingdifferent settings of the IDMTand DT curves available on the relay.The tripping times are measuredwith a chronometer and its accuracyis verified against the theoreticaltimes calculated.

Reduced commissioning:

Since the system is fully tested it isonly necessary to prove the relay onsite at the service settings, thereforereducing commissioning time to aminimum.Once the switchgear has beeninstalled and cabled up, it isimpractical or sometimesimpossible to carry out primaryinjection tests. It is suggested thatfor commissioning and maintenancepurposes either of the following twomethods can be used.1. Simple trip test using the VAP6test unit (described previously).

2. Secondary injection usingstandard equipment with an outputfilter.

Secondary injection:

Testing using secondary injection isused to test the following parts of theprotection system:n The electronic circuit.n The integrity of the power supplyof the VIP 30/35.n The link to the mitop trip coil andalso the circuit breaker mechanicaltripping mechanism.n The integrity of the switches onthe front panel to ensure theygive the correct tripping times forthe curves selected.

Caution:

n The ‘MITOP’ trip coil must be usedonly in conjuction with the VIP relay.

n Voltage withstand testing of theauxiliary and control circuits at 2000Vfor 1 minute should never be carriedout without disconnecting the MITOPtrip coil or the VIP relay.

n Secondary injection facilities areprovided on the terminal rail in the LVpilot cable box.

n No external connections should bemade to the VIP30/35 or the MITOPtrip coil.


Test set connections:The injection set is connected to the VIP 30/35 relay without disconnecting theCT’s.This is done via the sockets on the terminal rail located in the LVcompartment.

Phase overcurrent connections:To test the overcurrent protection the connection should be made across twoCT’s (C11-C31. C31-C51, C51-C11).

Earth fault connections:To test the earth fault protection, the connection should be made across oneCT (C11-C10, C31-C30, C51-C50).These numbers should be cross checked with the relevant circuit breakerschematic diagram. Terminals L1 and L4 (not shown above - seeRingmasterselection guide) give access to a normally open contact, which is normallyopenwhen the CB is in the open position. This can be used to connect atiming device to measure the opening time of the relay and circuit breaker.The type of test plug used to connect to the DIN rail connectors is a standard4mm 10A test plug.Note: When using a secondary injection set with VIP 30/35 a filter (e.g. FosterSF30) should be used to improve the wave form. If a filter is not used theoperating time of the relay may not follow the theoretical operating times.

Recommended testprocedure forsecondary injection:

The test procedure outlined here isonly a guide and may needmodifying to suit the different testsets available.The manufacturers instructionsshould be read before attempting tosecondary inject the VIP30/35 relay.

The VIP30/35 relays can besecondary injected like anyconventional 1A relay, therefore theoutput recommended for 1A relaysshould be used.

Calculate the secondary current tobe injected from the equivalentprimary current, taking into accountthe CT’s used .

With the VIP 30/35 connected so asto present the correct burden, thefollowing test can be carried out:

1. Setting check:

- Set the current to be injected ( atrue RMS ammeter should beused to measure the current).

- The CB should then be closedand the counter/timer reset.The current should then beapplied.

- When the CB has operated, theapplied current should beturned off if not doneautomatically.

- The time shown on the counterdisplay includes the operatingtime of the circuit breaker(approx. 90ms) The actual relayoperating time can then becalculated by subtracting thistime from the counter reading.
