All information concerning the phaseovercurrent is grouped together in theupper half of the front panel. Thesection numbers below are related tothe numbering on the drawing shownon page 4.

2. Phase overcurrentpick-up indicator.

When the red LED blinks, it indicatesthat the low set element has picked up.If the current does not decrease below

the pick-up level the relay will trip.

For IDMT curves (SI, VI, EI) theLED blinks when the current isgreater than 1.2 times the settingcurrent Is.

For the IDMT curve (RI), the LEDblinks when the current is greaterthan the setting.

For the DT curve, the LED blinkswhen the I> pick-up settingis exceeded.

Also refer to indicator reset button(page 9).

3. Phase overcurrent tripindicator.

The indicator is normally black andturns yellow when the phaseovercurrent has given a tripping order.It stays yellow, even when the relay isde-energised.

4. Setting current Is.

The setting depends on the current

transformer (CT) used, and the rangeselected via the connections made tothe back of the relay. The scale labelinserted should match the CT andrange selected. The switch can then bepositioned to the primary currentmagnitude required in amperes.

C. Indicator reset button

The reset button can be operated withthe sealable cover either open orclosed. When the button is pressed, thefollowing actions are initiated:

It resets the phase overcurrentand earth fault trip indicators.N.B.

If reset is more than 48 hoursafter the relay has operated andis left without being energised,the VAP6 must be used to resetthe trip indicators or the operatormust wait for the relay to bere-energised.

The two red LEDs light upsimultaneously for approximatelythree seconds to indicate thefollowing:- The relay is energized and theminimum operating current levelhas been reached.

-The relay self testing results arehealthy

N.B.If one of the two conditions is notmet, the indicators do not light up.

This function may be used tocarry out a basic relay operation test.

D. Minimum operatingcurrent

The minimum operating current is thephase current required for the relay tobe energized and operational. Thesetting depends on the CT used, andthe range selected via the connectionsmade to the back of the relay. Thevalue given on either side of the scalelabel is the single phase RMS minimumoperating current.

N.B. Regarding minimum operatingcurrent:

The VIP 300 does not operate belowthe minimum operating current level. Asa result, if the earth fault setting (Ios) isbelow the minimum operating current, itwill only take effect when there is phasecurrent greater than or equal to theminimum operating current.

Indicators

A On:

Indicates that the batteries areoperating. Also lights up when thebattery test is carried out bypressing battery test.

B Test in progress:

Confirms sending of the teststimulus to the VIP 300.

C Trip:Is used to test other relays in theVIP range. It is not to be

considered for the VIP 300 test (itlights up for a transient periodwhen the VIP 300 sends a trippingorder; whether or not the circuitbreaker is inhibited).

D External MITOP output:

This feature may be used toconnect an external MITOP tripcoil which could be used tooperate a timer etc. The externalcoil is triggered at the same timeas the circuit breaker MITOP. The

trip inhibit button does not effectthe external coil.

Batteries:

The batteries are normallydeactivated and are automaticallyactivated when the VAP6 isconnected to the VIP 300. Theyare activated in the followingcases:

- Pressing the battery testbutton.

- Direct connection to a VIP 300

relay.

To install or change the batteries,open the unit by removing the 4screws on the bottom of the unit.Be sure to use the correctpolarities.

Technical characteristics:

Supply: 3 x 9V 6LR61batteries

Weight: 0.45KG

Dimensions: 93 X 157 X 45mm

The VAP6 is a portable unit which isconnected to the VIP 300 to carry out

simplified testing.The test can be carried out in thefollowing two cases:

- the VIP 300 is already powered up by the sensors (CTs).

- The VIP 300 is not supplied. Inthis case, the VAP6 batteriessupply power to the relay.

Push buttons:

1 Battery test:

If the batteries are healthy, theon indicator(A) lights up whenthe button is pressed.

2 Phase overcurrent:

Sends the phase overcurrent teststimulus, which is equivalent to 20times the setting current Is.

3 Earth fault:

Sends the earth fault teststimulus, which is equivalent to 20times the earth setting currentIos.

4 Trip inhibition:

By pressing and holding thisbutton down the relay can betested with the VAP6 withouttripping the circuit breaker. Thisfacility will inhibit the circuitbreaker tripping even if a realfault occurs during the test.

VIP 300

VAP6 test sequence

The test consists of:

- Initiation of the VIP 300 self

monitoring and diagnostic routine.- Injecting a stimulus to stimulatea phase fault.

- Check tripping

* The VAP6 is supplied bybatteries. Therefore the parts ofthe VIP 300 that run on ACcurrent are not checked using thismethod (input and supplycircuits).

Press the phase overcurrent button tosend the test stimulus.

- Continue pressing the buttonthroughout the duration of thestimulus. The stimulus representsabout 20 times the setting currentIs.

-The VAP6 test in progressindicator lights up to confirm thesending of the stimulus to theVIP300 relay.

- The red I> indicator of theVIP300 blinks during the timerelay delay period.

- Then the VIP 300 phase trip

indicator turns yellow.- The circuit breaker trips if it isnot inhibited.

*If the phase overcurrent button isheld down after tripping, the VIP300starts the time delay/tripping cycleagain; this is normal operation.

In that case:

- The VAP6 red trip indicatorlights up for a transient periodeach time there is a trip.

- Depending on the time delay

setting, the VIP 300 red I>indicator may be off or blinkrapidly and/or in an irregularmanner.

Press earth fault to test the relaysoperation. The stimulus injected isequal to 20 times the setting currentIos. Use the procedure as for the phaseovercurrent test.

Disconnect the VAP6. In order to savebatteries, do not leave the VAP6connected to the relay unnecessarily.

The test may be carried out with orwithout the relay energised by the

Ringmaster current transformers, andall the relay settings are effective.During the test, the relay remainsoperational and will give a trippingorder in the event of a fault, unless thetrip inhibit button is pressed and helddown.

Connect the VAP6 to the VAP6 testplug. The VAP6 batteries are activated

and the on indicator lights up.

Press the trip inhibition button if thetest should be carried out withouttripping the circuit breaker.*Be sure to continue pressing thetrip inhibition button throughout thetime it takes to send the stimulus.

Commissioning Ringmaster with VIP 300

Secondary injection:

Testing using secondary injection isused to test the following parts of theprotection system:

The electronic circuit.

The integrity of the power supplyof the VIP 300.

The link to the mitop trip coil andalso the circuit breakermechanical tripping mechanism.

The integrity of the switches onthe front panel to ensure theygive the correct tripping times forthe curves selected.

Reduced commissioning:

Since the system is fully tested it is onlynecessary to prove the relay on site atthe service settings, therefore reducingcommissioning time to a minimum.Once the switchgear has been installedand cabled up, it is impractical orsometimes impossible to carry outinjection tests. It is suggested that forcommissioning and maintenancepurposes either of the following twomethods can be used.1. Simple trip test using the VAP6

test unit (described previously).

2. Secondary injection using

standard equipment with anoutput filter.

Factory tests:

All Ringmaster panel types are fullytested before leaving the factory. Thesetests include the whole protectionsystem including current transformers,wiring harness, relay, trip coil and thecircuit breaker itself using primaryinjection to energise the system.Tripping tests are carried out usingdifferent settings for each of the IDMTand DT curves available on the relay.The tripping times are measured with achronometer and its accuracy is verifiedagainst the theoretical times calculated.

Test set connections:The injection set is connected to the VIP 300 relay without disconnecting the CTs.This is done via the sockets on the terminal rail located in the pilot cable box, justabove the relay itself.

Phase overcurrent connections:To test the overcurrent protection the connection should be made across two CTs(terminal rails nos 4 to 5, 5 to 6 or 6 to 4).

Earth fault connections:To test the earth fault protection, the connection should be made across one CT(terminal rail nos 4 to 7, 5 to 7, or 6 to 7).These terminal numbers should be cross checked with the relevant circuit breakerschematic diagram. Terminals 15 and 16 (not shown above - see Ringmasterselection guide) give access to a normally open contact, which is normally openwhen the CB is in the open position. This can be used to connect a timing device tomeasure the opening time of the relay and circuit breaker.The type of test plug used to connect to the DIN rail connectors is a standard 2mm19A test plug.

Note: When using a secondary injection set with VIP 300 a filter (e.g. Foster SF30)should be used to improve the wave form. If a filter is not used the operating time ofthe relay may not follow the theoretical operating times.

Recommended test

procedure forsecondary injection:

The test procedure outlined here is onlya guide and may need modifying to suitthe different test sets available.The manufacturers instructions shouldbe read before attempting to secondaryinject the VIP 300 relay.

The VIP 300 relay can be secondaryinjected like any conventional 1A relay,therefore the output recommended for1A relays should be used.

Calculate the secondary current to beinjected from the equivalent primarycurrent, taking into account the CTsused and the range selected byconnections to the terminals on theback of the relay.

With the VIP 300 connected so as topresent the correct burden, thefollowing tests can be carried out:

1. Pick-up check

- Increase the current slowly untilthe appropriate LED indicatorstarts to blink.

2. 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. Thecurrent should then be applied.

- When the CB has operated, theapplied current should be turned

off if not done automatically.- The time shown on the counterdisplay includes the operatingtime of the circuit breaker(approx. 90mS). The actual relayoperating time can then becalculated by subtracting this timefrom the counter reading.

Note. - No connection should be made to the MITOP trip coil from the secondaryinjection test set.

*Note. These values exceed the rating of the circuit breaker
