ABB Relion 670 Series REL670 - Switching the Autorecloser for 1;2;3-Phase Operation Function to on and off; Verifying the Autorecloser Function SMBRREC

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 44.
5. Make arrangements for indication, recording and time measurements.
The signals for CBPOS, 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.
10.10.2.2 Switching the autorecloser for 1/2/3-phase operation function to
On
and Off
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 CB 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.
10.10.2.3 Verifying the autorecloser function SMBRREC
Select the test cases to be run according to what is applicable to the particular
application. It can be, for example,
• three-phase single-shot reclosing
• two-shot reclosing
• single-phase and three-phase single-shot reclosing
Below, a case with single-phase and three-phase single-shot reclosing is described.
1. Set Operation = On.
2. If the synchronizing check 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.
4. Simulate CBREADY by closing the switch SRY, and leave it closed.
5. Inject AC quantities to give a trip, for example, a one-phase trip, to the BR and
to the START input.
Observe and preferably record the operation. The BR relay shall trip and reclose
(start). After reclosing, the SRY switch can be opened for about 5s and then
closed again.
The autoreclosing 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
