摘　　要：电容器是一种全密封设备,其绝缘老化状况的判定十分困难。本文试图根据电容器极对壳绝缘的局部放电试验结果,对其绝缘老化进行判断。所得出的结果,对电容器运行有一定的参考价值。It is very difficult to predic insulation ageing of the power capacitor because it is a complete closed equipment. This paper tries to predict the insulation ageing of power capacitor according to the pole-to-case partial discharge test. The result of the paper is value to operation of the power capacitor.
