Checking the response when auto recloser is
Procedure
1. Check that the auto recloser is operative, for example by making a reclosing shot.
Set the autoreclosing operation to
The output
2. Apply a single phase fault and thereby a
3. Check that a definitive three phase trip and no auto reclosing takes place.
Testing auto reclosing in a multi-breaker arrangement
The usual arrangement is to have an auto recloser per circuit-breaker. They can be in different
circuit breaker related IEDs or in a common IED.
• A master auto recloser is set with
• A slave auto recloser is set with
The two auto reclosers can be checked individually by carefully applying
signals.
It is also possible to verify the two functions together by using circuit breaker simulating
equipment for two circuit breaker circuits. There should be interconnections from the master to
the slave function,
to above.
Restoring equipment
After the tests, restore the equipment to normal or desired state. Check the following items in
particular:
1. Check the operation counters.
Reset the counters to zero, if that is the user's preference. The counter reset function is
found on the local HMI under Main menu/Reset/Reset counters/AutoRecloser79,5(0–>1)/
SMBRREC(79,5(0–>1)):x
2. Restore settings that may have been modified for the tests back to normal.
3. Disconnect the test switch, circuit breaker simulating arrangement and test circuits.
Reconnect any links or connection terminals, which may have been opened for the tests.
4. Reset indications, alarms and disturbance recordings.
Clearing of the disturbance report can be done via the Disturbance Handling in PCM600 or
the local HMI.
