RELAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a relay device capable of facilitating phase correction. SOLUTION: A zero-phase current pulse signal and a zero-phase voltage pulse signal are sampled and stored in a prescribed timing. Read-out timing for the zero-phase current pulse signal or the zero-phase voltage pulse signal is changed corresponding to a case where a zero-phase reference input device is used or a case where a ground transformer is used.
