摘要
通过对XLPE电力电缆局部放电在线测试方法的研究,介绍了几种测试方法的原理,结合实际情况对其优缺点进行了分析、比较。得出在实际测试中,合理地组合运用多种测试方法,能取得更好的测试效果。
Through the research, this paper introduces the principle of several feasible methods of XLPE power cable on-line partial discharge detection. The characteristics and applications of different detection methods are also com- pared and analyzed respectively. In actual practice, it can achieve better the monitoring effect that reasonable combi- nation different methods of on-line partial discharge detection.
