If any timer settings are reduced to speed up or facilitate the testing, they shall be set to
normal after testing. A temporary label on the IED can be a reminder to restore normal
settings after which a verification test should be performed.
2. Decide if a synchrocheck function SESRSYN (25) shall be included in the test.
If SESRSYN (25) as an internal function or external device is not operated by the injection,
input signal SYNC must be connected as a permanent high signal or controlled by a switch.
3. Read and make notes of the reclosing operation counters on the local HMI under Main menu/
Test/Function status/Control/AutoRecloser79,5(0–>1)/SMBRREC(79,5(0–>1)):x
Possibly reset the counters to
4. Make arrangements for the simulation of the CB, for example as in Figure 54.
5. Make arrangements for indication, recording and time measurements.
The signals for ,52a, RI, CLOSECMD, READY and other relevant signals should preferably be
arranged for event recording with time tagging. If that is not possible, other means of time
measurement and recording should be arranged.

The circuit breaker should be closed and ready.
3. If external control inputs OFF/ON are used, check that they work. Set
and use the control inputs to switch On and Off, and check the state of the function.
11.10.2.3 Verifying the auto recloser
Select the test cases to be run according to what is applicable to the particular application. It can
be, for example,
• three-pole single-shot auto reclosing
• two-shot reclosing
• single-pole and three-pole single-shot auto reclosing
Below, a case with single-phase and three-pole single-shot auto reclosing is described.
1. Set
2. If the synchrocheck SESRSYN (25) is not to be operated, ensure that the signal SYNC input is
activated. If SESRSYN (25) is to be included, ensure that it is supplied with the appropriate
AC quantities.
3. Simulate CB closed position by closing switch SC to make the BR relay pick-up.
4. Simulate CBREADY by closing the switch SRY, and leave it closed.
5. Inject AC quantities to give a trip, for example, a one-pole trip, to the BR and to the RI input
of the auto recloser.
Observe and preferably record the operation. The BR relay shall trip and reclose (pick-up).
After reclosing, the SRY switch can be opened for about 5s and then closed again.
The auto reclosing open time and the sequence should be checked, for example in the event
recording. Check also the operation indications (disturbance report) and the operation
counters on the local HMI under Main menu/Test/Function status/Control/
AutoRecloser79,5(0–>1)/SMBRREC(79,5(0–>)):x
Should the operation not be as expected, this should be investigated. It could be caused by
an inappropriate setting or missing condition such as
6. Repeat the sequence by simulating a permanent fault.
