TRANSMISSION LINE ACCIDENT SECTION STANDARDIZATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a transmission line accident section standardization device that can discriminate a failure occurring in an associated line from a failure occurring in another line.;SOLUTION: According to detected currents in an overhead ground wire 1 output from current sensors 2a and 2b, a determination part 7 compares an induced waveform before the occurrence of a failure and an induced waveform after the failure occurrence to discriminate a failure in an associated line from a failure in another line according to whether the levels and phases of the induced waveforms are coincident or not.;COPYRIGHT: (C)2002,JPO
