1. Phase overcurrent setting area

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

2. Phase overcurrent pick-up indicator

When the red LED blinks, it indicatesthat the low set element has picked up.If the current does not decrease belowthe pick-up level the relay will trip. For IDMT curves (SI, VI, EI) the

LED blinks when the current is greater than 1.2 times the setting current Is.

For the IDMT curve (RI), the LED blinks when the current is greater than the setting.

For the DT curve, the LED blinks when the I> pick-up setting is exceeded.

Also refer to indicator reset button(page 9).

3. Phase overcurrent trip indicator

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

4. Setting current Is

The setting depends on the currenttransformer (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 current magnitude required in amperes.

Phase overcurrent 5. Choice of low set curve

SI : Standard inverse time.VI : Very inverse time.EI : Extremely inverse time.RI : Specific curve

- consult Merlin GerinDT : Definite time.Off : Low set is disabled.

6. Low set pick-up (DT only) I>

The setting is a multiple of Is. It is onlyactive when the low set curve type DT is selected.

If the tripping curve is selected withIDMT (selector switch 5 set to SI, VI, EI, RI) the selector switch has no effect.

7. Low set time delay t>

If the DT curve is selected, the value shown is the low set time delay.

For IDMT curves the value displayed is the tripping time for a phase current equal to 10 x Is.

8. Multiplying factor (low set)

In the x10 position, the time delay displayed on switch 7 is multiplied by10.

9. High set pick-up I>>

The high set is chosen as a multiple ofthe current Is. In the off position, thehigh set is disabled.

10. High set time delay t>>

Other functions A. Setting scale label The label indicates the range for

the phase overcurrent and earthfault primary amp settings. It isinserted from the top, behind thetransparent part of the front panel.

The label is reversible and is printed with the x2 range setting currents on one side, and the x4 range setting currents on the other. The scale label when inserted should match the CT and terminal positions on the rear of the relay, for the range required.

Also refer to testing and commissioning.

B. CT and range indication

The CT and range are given on eachside of the setting scale label. The labelwill match the appropriate CT for theRingmaster panel type supplied. Thisinformation is hidden when the label isinserted.

Choice of setting scale label

Make sure that the information given on the top of the label matches:1 - The current transformer used:

200/1A, 400/1A or 800/1A2 - The range used.

x2 or x4This information is hidden when thelabel is in position.

For help with the choice of range to select, refer to the application section.

Installation

Slide the setting scale into position behind the transparent part of the front face.

Make sure the label is pushed right into the bottom of the slot. To remove the label, use the hole in the top, if necessary with the help of the tip of a pencil or a screwdriver.

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 overcurrent

and earth fault trip indicators. N.B. If reset is more than 48 hours after the relay has operated and is left without being energised, the VAP6 must be used to reset the trip indicators or the operator must wait for the relay to be re-energised.

The two red LEDs light up simultaneously for approximately three seconds to indicate the following:- The relay is energized and the minimum operating current level has been reached.-The relay self testing results are healthyN.B.If one of the two conditions is not met, the indicators do not light up.

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

D. Minimum operating current

The minimum operating current is thephase current required for the relay tobe energized and operational. The setting 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 minimum operating current.

N.B. Regarding minimum operatingcurrent:The VIP 300 does not operate belowthe minimum operating current level.As a result, if the earth fault setting(Ios) is below the minimum operatingcurrent, it will only take effect whenthere is phase current greater than orequal to the minimum operating current.

E. VAP6 test plug

The test plug is exclusively designed forconnection of the VAP6 which is usedfor fast, simplified relay testing.The operation may be carried out whilethe relay is operating since the VAP6and VIP 300 provide the possibility oftesting with inhibition of circuit breakertripping.

Also refer to the testing and commissioning chapter.

VIP 300Overview of the VAP6

10

The VAP6 is a portable unit which isconnected to the VIP 300 to carry outsimplified testing.The test can be carried out in the following two cases:

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

- The VIP 300 is not supplied. In this case, the VAP6 batteries supply power to the relay.

Push buttons:

1 Battery test:If the batteries are healthy, the on indicator(A) lights up when the button is pressed.

2 Phase overcurrent:Sends the phase overcurrent test stimulus, which is equivalent to 20 times the setting current Is.

3 Earth fault:Sends the earth fault test stimulus, which is equivalent to20 times the earth setting current Ios.

4 Trip inhibition:By pressing and holding this button down the relay can be tested with the VAP6 without tripping the circuit breaker. This facility will inhibit the circuit breaker tripping even if a real fault occurs during the test.

VAP6 front panel IndicatorsA On:

Indicates that the batteries are operating. Also lights up when the battery test is carried out by pressing battery test.

B Test in progress:Confirms sending of the test stimulus to the VIP 300.

C Trip:Is used to test other relays in the VIP range. It is not to be considered for the VIP 300 test (it lights up for a transient period when the VIP 300 sends a tripping order; whether or not the circuit breaker is inhibited).

D External MITOP output:This feature may be used to connect an external MITOP trip coil which could be used to operate a timer etc. The external coil is triggered at the same time as the circuit breaker MITOP. The trip inhibit button does not effect the external coil.

Batteries:

The batteries are normally deactivated and are automatically activated when the VAP6 is connected to the VIP 300. They are activated in the following cases:

- Pressing the battery test button.- Direct connection to a VIP 300 relay.

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

The test may be carried out with orwithout the relay energised by theRingmaster current transformers, andall the relay settings are effective.During the test, the relay remains operational 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 activatedand the on indicator lights up.

Press the trip inhibition button if thetest should be carried out without tripping the circuit breaker.Be sure to continue pressing the trip inhibition button throughout thetime it takes to send the stimulus.

The test consists of:- Initiation of the VIP 300 self monitoring and diagnostic routine.- Injecting a stimulus to stimulate a phase fault. - Check trippingThe VAP6 is supplied by batteries. Therefore the parts of the VIP 300 that run on ACcurrent are not checked using this method (input and supply circuits).

Press the phase overcurrent button tosend the test stimulus.

- Continue pressing the button throughout the duration of the stimulus. The stimulus represents about 20 times the setting current Is.-The VAP6 test in progress indicator lights up to confirm the sending of the stimulus to the VIP300 relay.- The red I> indicator of the VIP300 blinks during the time relay delay period.- Then the VIP 300 phase trip indicator turns yellow.- The circuit breaker trips if it is not inhibited.

N.B. 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 indicator lights up for a transient period each time there is a trip.- Depending on the time delay setting, the VIP 300 red I> indicator may be off or blink rapidly and/or in an irregular manner.

Press earth fault to test the relaysoperation. The stimulus injected is equalto 20 times the setting current Ios. Usethe procedure as for the phase overcurrent test.

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

VIP 300Commissioning Ringmaster with VIP 300

12

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 or sometimes impossible to carry outinjection tests. It is suggested that forcommissioning and maintenance purposes 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 an output filter.

Factory tests: Secondary injection:Testing using secondary injection isused to test the following parts of theprotection system: The electronic circuit. The integrity of the power supply

of the VIP 300. The link to the mitop trip coil and

also the circuit breaker mechanical tripping mechanism.

The integrity of the switches on the front panel to ensure they give the correct tripping times for the curves selected.

Caution: The MITOP trip coil must be

used only in conjunction with the VIP relay.

Voltage withstand testing of theauxi l ia ry and control circuits at 2000 for 1 minute should never be carried out without disconnectingthe MITOP trip coil or VIP relay.

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

No external connections shouldbe made to the VIP 300 or theMITOP trip coil.

All Ringmaster panel types are fullytested before leaving the factory. Thesetests include the whole protection system including current transformers,wiring harness, relay, trip coil and thecircuit breaker itself using primary injection to energise the system.Tripping tests are carried out using different 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 Ringmaster selection 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.

- Increase the current slowly until the appropriate LED indicator starts to blink.

2. Setting check:

- Set the current to be injected (a true RMS ammeter should be used to measure the current).- The CB should then be closed and the counter/timer reset. The current should then be applied.- When the CB has operated, the applied current should be turned off if not done automatically.- The time shown on the counter display includes the operating time of the circuit breaker >80ms or
