self-powered protective relaysThe VIP30 and VIP35 relays aredesigned for use in distributionnetworks, mainly in MV/LVsubstations in which they provideprotection upstream from thetransformer.They are self-powered relays that donot require any auxiliary supply; theyare supplied by the current sensors.They actuate a Mitop release.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 as of 1.2 timesthe setting current (Is). The VIP30and VIP35 phase protections are thesame

earth protectionProtection against earth faultsoperates by measurement of residualcurrent based on the sum of thesensor secondary currents.Measurement is carried out by a

CSH30 core balance CT mounted onthe back of the VIP35 unit. Earthprotection operates with definite time;the setting and time delay areadjustable.

VIP30 WEDVIP30 WED has the samecharacteristics than VIP30.The difference between VIP30 WEDand VIP30 is only the marking on thescale label.

Fsee chapter 5 "choice of the

setting scale label".To set VIP30 WED, the selectorswitch must suit the rated power.

sensorsn CRc sensor of the RM6:(sensors for RM6s 1998 and later)The VIP30/35 relays must be usedwith the CRc sensors to obtain thespecified performances.- The CRc sensors have 2 ranges;according to the range used, thesetting current is adjustable from 8Ato 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.n other type of sensor:The use of other existing 200/1sensors calls for the addition of

protective resistors in series.

descriptionn The VIP30 and VIP35 relays aremounted in a polycarbonate injectedcasing which protects them againstdripping water and dustyenvironments.The front is protected by atransparent cover fitted with a sealingjoint. The cover may be lead-sealedto prohibit access to the settings.n Rotating selector switches are

used 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 sensor. This is done bypositioning a "setting scale label" onthe relay at the time of assembly.n The connection is made on theback of the relay using fast-on clips.

phase protection (VIP30 and VIP35)

1. phase protection zoneThe phase protection information isgrouped together in the dark zone ofthe upper half of the front face. Thiszone is the same for the VIP30 andVIP35

2. setting current IsTime-delayed tripping of the earthprotection takes place as of 1.2 x Is.According to the range used on thesensor, the setting current isadjustable from 8A to 80A or from20A to 200A; the selector switchscale is to be adapted to suit therange used by means of the settingscale label.

earth protection (VIP 35)

4. earth protection zone

This zone contains the earthprotection settings.

5. earth protection settingThe setting is made directly in MVamperes.

6. earth protection time delayThe earth protection time delay is setin seconds.

7. inrush current delayThis selector switch starts up theinrush current delay (1s). The timedelay prevents tripping by the earthprotection when the VIP35 isenergized upon making of the circuitbreaker. The time delay only activefor the earth protection and has noeffect on tripping by the phaseprotection.nin off position:The inrush current delay is notactivated. The earth protectionoperates according to the setting ofthe selector switch (6).nin on: positionThe inrush current delay is activated.

In this case:- when the VIP35 is energized, andthe circuit breaker makes, 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 (6).

FWhen the circuit breaker makes,

energizing of the MV/LV transformermay generate aperiodic inrushcurrents with a DC component thatmomentarily saturates the magneticcores of the VIP35 sensors. Becauseof this, each sensor gives anerroneous result and the sum of thephase currents (at the sensorsecondary windings) is no longerzero. There is false earth faultdetection that may cause tripping ofthe earth protection.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

- e.g. VIP35 setting scale label -

- how to install the setting scale label -

a. setting scale labeln It should be mounted on the

VIP30/35 when it is assembled on thecircuit breaker. The label indicatesthe scales of the phase settingcurrent (VIP30/35) and earthprotection setting (VIP35) selectorswitches. It is inserted, from the top,behind the transparent part of thefront face.Install the label according to:- the type of relay: VIP30 or VIP35- the range used on the CRc sensorn The label is printed on both sides.This means that it may be turnedaround if the range is changed duringthe service life of the installation.

Falso refer to the "assembly"chapter.

b. sensor used and wiringThe text is printed on the settingscale label. It indicates whichsecondary winding of the CRc sensoris to be used in accordance with thechosen range.When the label is in position in theslot, the text is hidden by and opaquezone. It is not visible to the user.

Falso refer to the "sensors andoperating ranges" chapter.

c. VAP6 test plugThe test plug is exclusively designed

for 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.The test is possible even if the relayis not supplied by the sensors. In thatcase, the VAP6 supplies theVIP30/35.

- testing of the VIP30/35 using theVAP6 -

d. minimum time delay switchn

The circular opening in the frontface gives access to switch which isused to time delay the tripping orderby at least 25 ms. The time delaymay be started up to prevent thecircuit breaker from breaking at thebeginning of the asymmetrical phasein 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 setting scalelabel.

3. sensors and operating ranges

sensors To obtain the performancesindicated, the VIP30 and VIP35 mustbe used with the specified sensors.

The relay/sensor assembly must beused together to comply with thetechnical characteristics indicated, inparticular:- operation across the range- tripping time- accuracy- short-circuit performanceIt is compulsory for the sensors ofeach of the phases to be of the sametype.

20A-200A 500/1 S1-S3

The secondary sensor has non-activeturns, the resistance of which protectsthe VIP30/35 in the event of a short-circuit in the MV network.

other 200/1 sensorsDifferent 200/1 sensors are alreadyused in the group. Their windingresistance is generally too low toensure protection of VIP30/35 in theevent of a short-circuit. It is necessaryto add a protective resistor Rp in

series with each sensor. Thecalculation of the resistor depends onthe characteristics of the winding andmagnetic core of the sensor.

notes1. When the VIP30/35 is used withCRc sensors, the 8-80A range, and

for I < 20A, the accuracy is derated inaccordance with the followingcharacteristics:- phase operating setting:

1.2Is -10% +30%.The tolerance is mainly due to thenon-linearity of the sensors for lowcurrents. The inaccuracy can reachthe limit above if the relay is onlysupplied by one phase. This may bethe case during single-phaseinjection testing.

2. Given for the operating setting at1.2 Is

3. Not applicable to the test plug

4. The times are measured for aphase-to-phase fault which appears

when the relay is already supplied(prior presence of a current in thenetwork that is greater than theminimum operating current). In theevent of closing in the presence of afault, the tripping times may beincreased by 20ms.The times indicated do not includethe mitop response time since itdepends on the circuit breaker (theno load mitop tripping time is lessthan 5 ms).

5. The tripping times are measuredfor a sinusoidal current.

6. When the VIP30/35 is used withCRc sensors, and for I < 30A, theaccuracy is derated in accordancewith the following characteristics:- earth protection setting:

10 % or 0/+6 AThe tolerance is mainly due to thenon-linearity of the sensors for lowcurrents. The inaccuracy can reachthe limit above if the relay is onlysupplied by one phase. This may bethe case during single-phaseinjection testing.

- VAP6 front panel -

The VAP6 is a portable unit that isconnected to the VIP30/35 to carryout simplified testing.The test can be carried out in thefollowing two cases:- the VIP30/35 is already supplied bythe sensors.- the VIP30/35 is not supplied. In thiscase, the VAP6 batteries supplypower to the relay.

The test consists of:- injecting a stimulus to simulate aphase fault.- injecting a stimulus to simulate anearth fault (VIP35).- checking tripping.

Frefer to the description of the testin the section entitled "test sequence"

F the VAP6 is supplied by batteries.Therefore the parts of the VIP30/35that run on AC current are notchecked using this method (input andsupply circuits).

push-buttonsnbattery test: if the batteries areOK, the "on" indicator lights up while

the button is pushed.n phase overcurrent: it sends thephase protection test stimulus. Thestimulus is equivalent to 20 times thesetting current Is.nearth fault: it sends the earthprotection test stimulus. The stimulusis equivalent to a current greater thanthe highest of the Io> settings.ntrip inhibition: press the "tripinhibition" button if the VIP30/35 testshould be carried out without trippingof the circuit breaker. Circuit breakertripping is inhibited while the tripinhibition" button is pressed, even if

the tripping order results from a realfault.

indicatorsnon: indicates that the batteries areoperating. Also lights up when thebattery test is carried out by pressing"battery test".ntest in progress: confirms sendingof the test stimulus to the VIP30/35.ntrip: it lights up when the VIP30/35sends a tripping order (whether or notthe circuit breaker is inhibited).

"external mitop" outputIt may be used to connect anauxiliary mitop designed, for instance,

to stop a stop watch during operatingtests. The mitop is triggered at thesame time as the circuit breakermitop. It is not inhibited by pressingthe "trip inhibition" button.

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 a VIP3X orVIP5X relay.- connection to the adapter corddesigned for testing of the VIP1X orVIP2X relays.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.

7. testing of the VIP30/35 and use of the VAP6 (contd)

VAP6 test sequence

The test may be carried out with or

without current in the sensors. Duringthe test operations, all the VIP30/35settings are effective; the relayshould perform in accordance withthe settings. During the test, the relayremains operational and will give atripping order in the event of a fault,unless the "trip inhibition" button ispressed.

n connect the VAP6 to the "VAP6test plug". The VAP6 batteries areactivated and the "on" indicator lightsup.

n press the "trip inhibition" button ifthe test should be carried out withouttripping of the circuit breaker.

Fbe sure to continue pressing the"trip inhibition" button throughout thetime it takes to send the stimulus.

n press the "phase overcurrent"button to send the phase protection

test stimulus.- continue pressing the buttonthroughout the duration of thestimulus.- the VAP6 "test in progress" indicatorlights up to confirm the sending of thestimulus to the VIP30/35 relay.- the VAP6 red "trip" indicator lightsup to indicate that the relay hastripped.- the circuit breaker trips if it is notinhibited.

F if the "phase overcurrent" button isheld down after tripping, the VIP30/35

maintains the tripping order. This isnormal operation.In that case:- the VAP6 "trip" indicator remains it.- the circuit breaker mitop is suppliedby the tripping order.

n press "earth fault" to test operationof the earth protection (VIP35). Usethe same procedure as for the phaseprotection test.

n disconnect the VAP6.In order to save batteries, do notleave the VAP6 connected to the

relay unnecessarily.
