Level 1 Relay Protection Operator
PRC-001-1.1 (ii): System Protection Coordination
If a protective relay or equipment failure reduces system reliability, the Transmission Operator shall notify its Reliability Coordinator and affected Transmission Operators and Balancing Authorities.
Power System Elements
Meeting this goal requires relays to accurately distinguish whether a fault is on the protected line, or external to it. The only way to accomplish this and to simultaneously trip all line
