摘要
电力电缆绝缘损坏主要由水树枝劣化引起,对电力电缆进行带电检测是非常必要的,低频交流电压叠加法是目前比较好的一种检测方法,本文对该方法的原理和软硬件设计方法作了介绍。
As the damage of power cable insulation is usually caused by water tree deterioration, it is very important to make online diagnosis on power cables. One of the good diagnostic methods nowadays is the low frequency AC voltage superimposition method. This paper presents the principle and design of hardware and software of this diagnostic method.
