Abstract

PURPOSE: When receiving signals are mistaken owing to the distrurbance of a communication line or the like, by shortening the lock time of a relay decision part as much as possible, a high speed cut off is perfomed at the time of heavy fault, even if signal errors and real faults occur concurrently.
