Testing auto reclosing in a multi-breaker arrangement
M12400-185 v7
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 Priority = High .
• A slave auto recloser is set with Priority = Low .
See the application manual for an illustration of typical
interconnections.
The two auto reclosers can be checked individually by carefully applying START ,
WAIT , and INHIBIT 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,
WFMASTER - WAIT , and
UNSUCCL - INHIBIT , as shown in the illustration referred to above.
Restoring equipment
M12400-190 v6
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.
11.10.2.5 Completing the test
M12400-218 v5
Continue to test another function or end the test by changing the TESTMODE
setting to Off . Restore connections and settings to their original values, if they were
changed for testing purposes.
11.10.3 Apparatus control APC
M13385-2 v6
The apparatus control function consists of four types of function blocks, which are
connected in a delivery-specific way between bays and to the station level. For that
reason, test the total function in a system, that is, either in a complete delivery
system as an acceptance test (FAT/SAT) or as parts of that system.
