Section 11
Testing functionality by secondary injection
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,
referred 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.

Completing the test

continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
11.9.3

Apparatus control APC

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.
11.9.4

Voltage control TR1ATCC, TR8ATCC, TCMYLTC, TCLYLTC

Prepare the IED for verification of settings as outlined in section
section
The automatic voltage control for tap changer, single control TR1ATCC is based on a
transformer configuration that consists of one tap changer on a single two-winding power
transformer.
The automatic voltage control for tap changer, parallel control TR8ATCC, if installed, may be
set to operate in Master Follower (MF) mode, or Minimise Circulating Current (MCC) mode. The
commissioning tests for each parallel control mode are addressed separately in the following
procedure.
Secondary injection of load current (I
are required during installation and commissioning tests. The test consists mainly of:
154
WFMASTER - WAIT , and UNSUCCL - INHIBIT , as shown in the illustration
If a block/unblock command is sent from remote to function, while the IED is
shut down, this command will not be recognized after the start up, thus the
command that was sent prior to the shut down is used. In such cases, where
there is a mismatch, the user is advised to make a complete cycle of block/
unblock operations to align the statuses.
