- 23[KV] 특고압 지중배전선로의 지락고장 발생시에 고장위치를 신속하게 찾을 수 있도록 하는 접속점별 고장구간표시방법 중에서, 접속점에서 접속되는 두 개의 전력케이블 중성선을 접지할 때에, 두 개의 중성선이 하나의 접지단자에 체결되는 지중배전선로방식에서의 접속점별 고장구간표시장치에 있어서,두 개의 전류센서와 하나의 동작코일로 구성하고,지중배전선로 접속점에서 접속되는 두 개의 전력케이블 중성선이 하나의 접지단자에 체결되기 전의 각각의 중성선 부위에서 중성선전류를 측정하는 전류센서를 설치하고,이 두 개의 전류센서 2차측 단자를 직렬로 결선하되 2차측 전류의 방향이 서로 반대가 되도록 결선하여, 평소에는 두 개 전류의 벡터적 합이 영(Zero)에 가까운 값이 되게 하고,접속된 두 개의 전력케이블 중에서 어느 하나의 전력케이블에 지락고장이 발생한 경우에는 , 지락고장이 발생한 전력케이블측의 전류센서에서의 검출값이 크게 되어, 두 개 전류의 벡터적 합이 크게 나타나게 함으로써, 동작코일을 작동시켜 지락고장이 발생한 전력케이블 구간을 표시하게 하는 것을 특징으로 하는 지중배전선로 접속점별 고장구간검출방법.
