Abstract

In this paper, it's described the techniques for the analysis of corona generated in open live parts of electric facilities. At needle-plane electrodes, when the voltage increased($0{\sim}70kV$, ramping 10kV) using the high voltage generation system(HIPOTRINICS $0{\sim}200kV$, USA), it's generated the partial discharge. There are compared between UV detected image and PD quantity. As these results, UV areas and gains are normalized. And electric facilities are evaluated the 5 steps such as 'good', 'recognition', 'check', 'inspection', 'change(replacement)'.
