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are released, the handle can be completely withdrawn from the test switch,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.
9.4 Connecting the test equipment to the IED
M11744-2 v9
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.
