A misoperation occurred when an overhead ground wire on a 230KV transmission line between two substations broke and fell across A phase of the line. One of the line circuit breakers failed to open causing the breaker failure relay to pick up and as a result tripped the entire substation bus off line that the failed circuit breaker was feeding off of. Who is charged with the responsibility to develop procedures to ensure misoperations are reviewed and analyzed to determine proper mitigation plans...

Q32618 When a high voltage transmission line circuit breaker trips open as a result of a fault, a synchronous check relay will monitor certain values on both the line side and the bus side of the open circuit breaker. Before the synchronous check relay re-closes the open circuit breaker, which of the following values has to be within a certain limit before the circuit breaker will close automatically? - ANSWER-•) Frequency •) Voltage Magnitudes •) Phase Angle between the voltages •) A...
