Abstract

Surges generated by direct strike or induction of lightning, frequent opening and closing of power system breakers, etc. cause excessive overvoltage, which can interfere with normal operation of transformers, circuit breakers, and power equipment. In order to prevent such phenomena, this study goes further from the method of establishing countermeasures by installing lightning arresters on power equipment or lines in parallel, and furthermore, remotely checking the condition of the lightning arrester and preparing immediate countermeasures when an event occurs. The purpose of the study is to prevent damage in advance.

낙뢰의 직격이나 유도에 의해 발생되는 서지, 전력계통의 차단기의 빈번한 개폐동작 등은 과도 과전압이 발생하며 이는 변압기, 차단기, 전력기기의 정상운전에 지장을 초래하게 된다. 본 연구는 이러한 현상을 예방하기 위해 전력기기 또는 선로에 피뢰기를 병렬로 설치하여 대책을 수립하는 방법에서 한층 더 나아가 원격으로 피뢰기의 상태를 점검하며 이벤트 발생 시 즉각적인 대책을 마련하여 부가적으로 발생하는 피해를 미연에 방지함에 그 연구의 목적이 있다.
