InstallationActuators

Procedure for fitting and setting of actuators fitted to the Ringmaster range of switchgearCN2, SN6, CE2, CE6, SE6

1 Fix the actuator to the top mounting bracket ensuring that the distance from the top of the actuator to the top of the mounting bracket is approximately 9mm (as shown in the drawing below) and tighten the fixing screw. Note: this is only an approximate preliminary setting.

2 Also ensure there is approximately 3mm of clearance between the body of the actuator and the facia of the unit (as shown in the drawing below).

3 Rotate the bottom of the actuator in a clockwise direction (if looking from below as shown in the drawing) until resistance against the actuator motor can be felt.

4 Then rotate the actuator in an anticlockwise direction approximately one half of a full rotation making sure that the actuator motor is not rotating (this has the effect of lengthening actuator i.e. gap ‘a’ on the drawing should increase).

5 Fit the actuator operating bracket assembly to the bottom of the actuator locating the operating bracket spigot in the operating handle socket (as shown in the drawing below) and tighten up the fixing screw.

6 Connect the actuator plug and perform a few electrical operations.

7 Remove the plug and check that the actuator can be withdrawn and replaced with relative ease.

8 If not, adjust the positioning of the actuator by loosening either the mounting bracket or operating bracket and moving either part so that the actuator can be withdrawn easily. Repeat this process until it is possible to withdraw the actuator with relative ease.

IMPORTANTIn the event that the actuator failsto complete a closing or openingoperation, DO NOT attempt todisconnect the actuator operatingbracket spigot from the operatinghandle socket.Contact Schneider Electric, details onpage 3.

Recommended Time fuse Link (TFL) settings to ESI 12 - 6

All circuit breakers can be fitted with various forms of protection system -

1. VIP self powered IDMT protection - refer to VIP user guidesVIP 30 - provides protection against phase-to-phase faultsVIP 35 - provides protection against phase-to-phase faults and earth faultsVIP 300 - three phase overcurrent and earth fault protection

2. Time fuse link (TFL) protection system to EA 41-26 (time fuse links to EA 12-6).

Time fuse link protection provides a cost effective way of protecting a transformerof 1600kVA or less. It is a recognised method of protection and the fuses are covered by EA 12-6 (1973). The arrangements in the Ringmaster range is of 2 phase overcurrent and earth fault.

Schneider Electric recommend TFL sizes in accordance with the table below.

The table also includes our recommendations for the maximum LV fuse size toensure discrimination. Note that the size of this fuse is less than the full load current of the transformer, however, it would normally be expected to have a number of LV fuses fed from the LV side of the transformer.

Important note: Please ensure TFL fuses are fitted prior to energising the equipment.

ProtectionOperation

The circuit consists of 3 dual ratioC.T.'s, 2 Direct Acting Trip (DAT) solenoid type overcurrent coils connected in parallel with associatedTime Fuse Links (TFL's) and 1 instantaneous earthfault DATsolenoid Coil.

Under normal load conditions on, sayan 11000 volt 1000KVA transformer, 52amps will flow in the C.T. primaries(1000kVA(11kv/3). If the C.T. ratio isset on 50/5 Amp ratio, then approximately 5 Amps will flow in theC.T. Secondaries. As the overcurrentcoils are shorted out by the fuses, nocurrent will flow through the coils.Assuming that there was no earthleakage, the red, yellow and blue phases will balance, and no current willflow through the earth fault coil.

In the event of a phase to phase faultof, say, 500 Amps, 50Amps would flowthrough the C.T. secondaries. Thiswould blow the 15Amp fuse links shunting all of the current through theDAT coils, which would operate and trip the 3 phase circuit breaker. Thetripped on fault flag would operate, andthe CB would have to be re-set and thefuses replaced.

Two overcurrent coils are required tocover all phase fault combinations, i.e.for a R-Y phase fault, the CB will trip on the red phase coil. Under earth fault conditions, there will be an imbalance between the red, yellow andblue phases, and current will flow downthe residual path of the C.T.'s andthrough the earth fault coil. The unitwill trip instantaneously. If a TFL is fitted in parallel with the earthfault coilthen the tripping time will follow the TFL characteristics. Alternatively, thefuse can be removed.

All information concerning earth faultsettings are grouped together in thelower half of the front panel. Sectionnumbers below are related to the numbering on the drawing shown onpage 46.

12 Earth fault pick-up indicator

When the red LED blinks, It indicatesthat the low set element has pickedup. If the current does not decreasebelow the pick-up level the relay willtrip.■ 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 blinkswhen the l> pick-up setting is exceeded.

N.B. The LED only blinks when thephase current is greater than the minimum operating current (refer tominimum operating current, page 51) Also refer to “indicator reset button”(page 51).

13 Earth fault trip indicator

The indicator is normally black andturns yellow when the earth fault element has given a tripping order. Itstays yellow, even when the relay is de-energised.

14 Setting current Ios

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 thenbe positioned to the primary amp valuerequired.For earth fault relay operation: linkbetween contacts 2 and 9 (x2 range)and 1 and 9 (x4 range) must be madeat back of relay.

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 LED’s 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 outa 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.

Fitting of reversible scale label


ProtectionVAP6

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 (CT’s).- 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 Indicators

A ■ 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 300relay.

■ 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 the“trip 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.

CommissioningCommissioning Ringmaster with VIP 300

Since the system is fully tested it is only necessary to prove the relay on site at the servicesettings, therefore reducing commissioning time to a minimum.Once the switchgear has been installed and cabled up, it is impractical or sometimes impossible to carry out injection tests. It is suggested that for commissioning and maintenance purposes either of the following two methods 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:

Testing using secondary injection is used to test the following parts of the protection 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.

■ The “MITOP” trip coil must be used only in conjunction with the VIP relay.■ Voltage withstand testing of the aux i l ia ry and control circuits at 2000V AC for 1 minute

should never be carried out without disconnecting the MITOP trip coil or VIP relay.■ Secondary injection facilities are provided on the terminal rail in the pilot cable box.■ No external connections should be made to the VIP 300 or theMITOP trip coil.

All Ringmaster panel types are fully tested before leaving the factory. These tests include thewhole protection system including current transformers, wiring harness, relay, trip coil and thecircuit breaker itself using primary injection to energise the system. Tripping tests are carriedout using different settings for each of the IDMT and DT curves available on the relay. Thetripping times are measured with a chronometer and its accuracy is verified against the theoretical times calculated.

Note: When using a secondary injectionset with VIP 300 a filter (e.g. FosterSF30) should be used to improve thewave form. If a filter is not used theoperating time of the relay may not follow the theoretical operating times.

Secondary injection

Test set connections: The injection set is connected to the VIP 300 relay without disconnecting the CT’s. This isdone via the sockets on the terminal rail located in the pilot cable box, just above the relayitself.

Phase overcurrent connections: To test the overcurrent protection the connection should be made across two CT’s (terminalrails no’s 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 no’s 4 to 7, 5 to 7, or 6 to 7).These terminal numbers should be cross checked with the relevant circuit breaker schematicdiagram. Terminals 15 and 16 (not shown above - see Ringmaster selection guide) giveaccess to a normally open contact, which is normally open when the CB is in the open position. This can be used to connect a timing device to measure the opening time of therelay and circuit breaker.The type of test plug used to connect to the DIN rail connectors is a standard 2mm 19A testplug.



1. Pick-up check- 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 <100ms. The actual relay operating time can then be calculated by subtracting this time from the counter reading.

Recommended test procedure for secondary injection:

Note: No connection should be made to the MITOP trip coil from the secondary injection test set.

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

The test procedure outlined here is only a guide and may need modifying to suitthe different test sets available.

The manufacturers instructions should be read before attempting to secondaryinject the VIP 300 relay.

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

Calculate the secondary current to be injected from the equivalent primary current,taking into account the CT’s used and the range selected by connections to theterminals on the back of the relay.

With the VIP 300 connected so as to present the correct burden, the following testscan be carried out:
