Bay control REC670 2.1 IEC
Commissioning manual
Testing functionality by secondary injection
example, 10s. It may thus be low at the instant of reclosing. After each Open or Close
operation it may need a recharging period before it goes high again.
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
