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...

NERC Test | 222 Questions| WITH COMPLETE SOLUTIONS What percentage of load gives a 1 Hz change in an island condition? Answer-6-10% (Think 6-10 day island vacation) If ACE is Zero but system Hz is off, what should a system operator do? Answer-Nothing! ACE bias and interchange schedule will improve frequency If ACE is Zero, why not adjust generation to help frequency? Answer-Could overload equipment, this is a NERC violation When restoring from blackout condition, what should be done wi...
