In the example of CB simulation arrangement, the CBREADY condition is
simulated by a manual switch, SRY.
Information and material for the verification:
•
Protection or control unit, IED, configured and with settings entered.
•
Configuration diagram for the IED
•
Terminal diagram for the IED, or plant circuit diagram including the IED
•
Technical reference manual for the IED
•
IED test set for secondary injection
•
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
