Figure 74: Logic for start of circuit breaker spring charging
Two separate trip circuit supervision functions are included, TCSSCBR1 for power
output X100:PO3 and TCSSCBR2 for power output X100:PO4. Both the functions
are blocked by the master trip TRPPTRC1 and TRPPTRC2 and the circuit breaker
open signal.
It is assumed that there is no external resistor in the circuit breaker
tripping coil circuit connected in parallel with the circuit breaker
normally open auxiliary contact.
