Abstract

본 발명은 해저케이블 고장점 탐색 시스템 및 방법에 관한 것이다. 본 발명에 의한 해저케이블 고장점 탐색 시스템은 방전유도전압을 발생하는 고전압발생기, 고전압발생기로부터 인가된 방전유도전압에 의해 해저케이블의 고장점에서 발생하는 수중방전을 검출하는 수중방전 검출기 및 수중방전 검출기로부터 검출된 수중방전의 정보를 통해서 해저케이블의 고장점을 탐지하는 수신기를 포함한다. 본 발명에 의한 해저케이블 고장점 탐색 시스템에 의하면, 해저케이블의 고장점에서 누설전류 및 누설자계의 변화량이 작은 경우에도 고장점의 상세 위치 탐색이 가능하다는 이점이 있다.
