ABSTRACT:
Disclosed is an improved reactance type protective relay that increases security against false tripping while still providing desired protection for a high voltage transmission line. The improved reactance relay employs a circuit arrangement having characteristic timers that optimize the performance of the reactance relay and also allows for desired coordination between the reactance relays that may be located along the high voltage transmission line.
