TIME DELAY SIGNAL DEVICE ESPECIALLY FOR PHASE COMPARISON PROTECTIVE RELAYING SYSTEM

摘要

A phase comparison relaying network which permits the delaying of the local signal which responds to the alternating current at the local terminal of the alternating current transmission line for an interval which may be greater than the time interval of 180 DEG of the alternating current whereby to compensate for time delay in the transmission from the remote terminal of the alternating current transmission line to the local terminal a signal responsive to the alternating current at the remote terminal when the time of transmission is greater than the 180 DEG interval.
