Abstract

본 발명은 코로나 검출 장치 및 방법에 관한 것이다. 본 발명의 일 측면에 따르면, 코로나 검출장치는 전력설비에서 발생되는 코로나 방전을 감지하는 감지부, 상기 감지된 코로나 방전을 전압 신호로 변환하는 신호처리부 및 상기 변환된 직류 신호를 이용하여 전력 설비의 이상 정도를 판단하는 제어부를 포함할 수 있다. 본 발명은 코로나 빛을 감지하여 코로나 방전 정도를 수치화 표시하여 전력설비의 이상 정도를 정확하게 판단할 수 있고, 특별한 숙련 없이 전력 설비의 이상 유무를 판정할 수 있고 전력시설에 대한 순시 및 점검 시에 간편하게 휴대하거나 차량에 탑재하여 짧은 시간에 넓은 범위의 설비에 대한 검사를 수행할 수 있어 운영상에 제약요소가 적다.
