Zusammenfassung:The present invention relates to an apparatus for sensing partial discharge of a power cable and a method for diagnosing partial discharge of a power cable connection unit using the same. The apparatus for sensing partial discharge of a power cable comprises: a rod-shaped supporter; a detection unit provided on an end part of the supporter and installed to come in contact with one side of an outer perimeter surface of the cable connection unit to measure a signal and detect a discharge signal; and an adhering unit in which one side is fixed to the detection unit and which is formed to cover the cable connection unit. The present invention can facilitate diagnosis work for partial discharge and perform diagnosis in a close location. 본 발명은 전력케이블의 부분방전 감지 장치 및 이를 이용한 케이블 접속부의 부분방전 진단 방법에 관한 것으로, 전력케이블의 부분방전 감지 장치는 봉 형상의 지지대, 지지대의 단부에 구비되고 케이블 접속부의 외주면 일측에 접촉되도록 설치되어 전자파 신호를 측정하여 부분방전 신호를 검출하는 감지부, 일측이 감지부에 고정되고 케이블 접속부를 감싸도록 형성된 밀착부를 포함하여 부분방전 진단작업이 수월하며 근접한 위치에서 진단이 가능하다.
