Abstract :
The advances in relay test sets, personal computers (PC), and the availability of satellite clocks have taken fault-simulated, end-to-end relay testing by secondary injection to new heights. This creative approach to relay testing allows relay technicians and engineers to comprehensively check line relays and evaluate their dynamic response to faults without staging actual faults on energized transmission lines. The testing technique offers flexibility, speed, and accuracy in testing line relays
