Abstract
Total monitoring device of leakage current in transformer can detects the flowing leakage current on the ground wire connected with the neutral point, and that is monitored at real-time by the transfer. If the over-flowing current is detected, Total monitoring device of leakage current in transformer will warn the administrator to prevent electrical accident. In this thesis, we are going to explain about Total monitoring device of leakage current in transformer. Also we measure leakage current and judge safety in customer.
변압기 누설전류 통합 감시 장치는 변압기 중성점 접지선에 흐르는 누설전류를 검출하여 실시간으로 모니터링이 가능한 장치로, 지정 값 이상의 누설전류가 검출되면 관리자에게 경보함으로써 전기적인 사고를 사전에 예방할 수 있다. 본 논문에서는 변압기 누설전류 통합 감시장치에 대해 설명하고 실제 변압기 누설전류 통합 감시장치가 설치된 수용가의 누설전류량 측정을 통해 안전성 여부를 판단하였다.
