1. Check the function settings on the local HMI under Main menu/
Settings/IED Settings/Control/Autorecloser79,5(0–>1)/
SMBRREC:x(79,5(0–>)):x
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 shall be included in the test.
If SESRSYN 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 Zero. Counters are reset in the reset menu.
4. Make arrangements for the simulation of the CB, for example as in Figure 29.
5. Make arrangements for indication, recording and time measurements.
The signals for CBCLOSED, START, CLOSECB, 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.
Switching the auto recloser to
1. Set the Operation setting to Off and check the state.
2. Set the Operation setting to On and check the state, including SETON and
READY.
The circuit breaker should be closed and ready.
3. If external control inputs OFF/ON are used, check that they work. Set
ExternalCtrl = On and use the control inputs to switch On and Off, and check
the state of the function.

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,
• single-shot reclosing
• two-shot reclosing
Below, a case with single-shot reclosing is described.
1. Set Operation = On.
2. If the synchrocheck SESRSYN is not to be operated, ensure that the signal
SYNC input is activated. If SESRSYN 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 start.
