Figure 14: Simulating the CB operation by a bi-stable relay/breaker simulator and
manual switches
9.6.2.1
Preparation of the verification
M12400-40 v8
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
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.
9.6.2.2
Switching the auto recloser to On and Off
On and Off
M12400-79 v9
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.
