Abstract

PURPOSE: To discriminate the direction of the fault in the circuit by securing a display with use of the aural frequency monitor signal which is transmitted from the monitored side to the monitor side via the backward monitor signal transmission contact that is continued or intermitted, and thus to ensure monitoring with a high transmission quality and high reliability.
