Preparation Of The Verification; Switching The Autorecloser For 3-Phase Operation Function To - ABB Relion 650 Series Commissioning Manual

Testing functionality
• Means to indicate, measure and record operation and times, for example an event
recording facility
• A bi-stable relay (BR) or two auxiliary relays to simulate a CB
• Two push-buttons (SC, ST) to operate the BR and a change-over switch (SRY) to simulate
CBREADY
• Possibly a switch simulation the synchronizing check SESRSYN condition

Preparation of the verification

1. Check the function settings on the local HMI under Main menu/Settings/IED Settings/
Control/SMBRREC(79,0->1)/SMBRREC:1
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 synchronizing check 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/Tests/Function status/Control/SMBRREC(79,0->1)/SMBRREC:1
Possibly reset the counters to
4. Make arrangements for the simulation of the CB, for example as in figure 24.
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.
