Preparing the connection to the test equipment

M11743-2 v7

The IED can be equipped with a test switch of type RTXP8, RTXP18 or RTXP24. The test switch

and its associated test plug handle (RTXH8, RTXH18 or RTXH24) are a part of the COMBITEST

system, which provides secure and convenient testing of the IED.

When using the COMBITEST, preparations for testing are automatically carried out in the

proper sequence, that is, for example, blocking of tripping circuits, short circuiting of CT’s,

opening of voltage circuits, making IED terminals available for secondary injection. Terminals 1

and 8, 1 and 18 as well as 1 and 12 of the test switches RTXP8, RTXP18 and RTXP24 respectively

are not disconnected as they supply DC power to the protection IED.

The RTXH test-plug handle leads may be connected to any type of test equipment or

instrument. When a number of protection IEDs of the same type are tested, the test-plug

handle only needs to be moved from the test switch of one protection IED to the test switch of

the other, without altering the previous connections.

Use COMBITEST test system to prevent unwanted tripping when the handle is withdrawn,

since latches on the handle secure it in the half withdrawn position. In this position, all

voltages and currents are restored and any re-energizing transients are given a chance to

decay before the trip circuits are restored. When the latches are released, the handle can be

completely withdrawn from the test switch, restoring the trip circuits to the protection IED.

If a test switch is not used, perform measurement according to the provided circuit diagrams.

Never disconnect the secondary connection of a current transformer circuit

without first short-circuiting the transformer's secondary winding. Operating a

current transformer with the secondary winding open will cause a massive

potential build up that may damage the transformer and cause personal injury.

Connecting the test equipment to the IED

M11744-2 v7

Connect the test equipment according to the IED specific connection diagram and the needed

input and output signals for the function under test. An example of a connection is shown in

figure 

9

.

Connect the current and voltage terminals. Pay attention to the current polarity. Make sure

that the connection of input and output current terminals and the connection of the residual

current conductor is correct. Check that the input and output logical signals in the logic

diagram for the function under test are connected to the corresponding binary inputs and

outputs of the IED under test.

To ensure correct results, make sure that the IED as well as the test equipment

are properly earthed before testing.
