Development of arrester leakage current detector using computer

컴퓨터를 이용한 피뢰기 누설전류 분석장치 개발

In this paper, the results of development of arrester leakage current detector using micro computer are described. This detector is based on harmonic analysis of the leakage current by FFT. For low sensitivity to disturbance, this device used optical fiber. This will be a great benefit of detecting deterioration ZnO arrester.
