CHAPTER 5: SETTINGS
CONTROL ELEMENTS
— Sets a time delay that inhibits closing after the bank has been switched out-of-service (the
CAP 1 DISCHARGE TIME
CAP
setting goes low or trip command terminates) until the bank has had time to discharge any trapped charge.
BKR CLSD 52a
The correct value for this setting depends on the specifics of the capacitor installation.
— Selects a FlexLogic operand that triggers the CAP 1 BKR CLOSE interlock logic. Its signal is expected
CAP 1 BKR CLOSE BLK
to originate from capacitor breaker trips external to the relay, and thus not otherwise able to block relay closing (for
example, from the opposite group's capacitor protection).
— Selects a FlexLogic operand that overrides all inhibits for the breaker close command and allows the
CAP 1 CLS OVERRIDE
CLOSE command to be issued from any source as per the logic diagram.
