Abstract
Description
Claims (1)
- 중성점 다중접지 배전선로에 전력(22.9㎸-Y)을 공급하는 변전소의 주변압기 2차측 중성선로에 설치된 고장전류 제한장치(=한류리액터)의 단선유무를 감시하는 한류리액터의 단선감시 시스템에 있어서,상기 한류리액터의 양단자(兩端子)에 접속된 전력선통신모뎀과, 상기 한류리액터의 내부권선을 통해 상시적인 전력선 통신을 수행하는 전력선 통신수단과,상기 전력선 통신수단에 의한 전력선통신이 단절되는 경우를 상기 한류리액터의 단선으로 판정하여 경보를 송출하는 경보수단을 포함하는 것을 특징으로 하는 한류리액터의 단선 감시시스템.
