ACTIVE UNDERGROUND POWER CABLE LINE TESTER AND TESTING METHOD

摘要

The present embodiment relates to an apparatus and method for detecting a live line of an underground power cable, comprising: a reference point detector for detecting a current magnitude, a phase and a specific noise of a cable in a reference point switch; and generating and injecting a pulse wave into a cable in the reference point switch A pulse wave generation unit, a reference point control unit receiving the result signals of the reference point detection unit and the pulse wave generation unit and transmitting the result, and a detection point measuring unit measuring the current magnitude, phase and specific noise of the detection point cable, and a pulse wave and an exploration control unit for determining whether a cable is connected by comparing the measurement result of the detection point measurement unit with the result signal transmitted by the reference point control unit.
