摘　　要：介绍了一种基于振荡波理论的振荡波电压测试系统及其国内外研究现状;讨论了该测试系统在电力电缆的耐压试验、局部放电检测中的应用。研究表明,振荡波电压与交流电压具有良好的等效性,且与交流电压、超低频电压(0.1 Hz)相比,作用时间短、操作方便,可发现XLPE电力电缆中的各种缺陷,不会对电缆造成损伤,因此振荡波电压测试系统具有良好的应用前景。Along with the wide use of XLPE power cable in the electrical power system, its test engineering and test method have been becoming more and more important. The paper introduces a kind of oscillatory wave voltage test system based up on oscillatory wave theory and its research status at home and abroad, discusses its application in the withstand voltage test and partial discharge detection of power cables. It is proved that oscillatory wave voltage have good equivalence with alternating voltage, and compared with alternating voltage and very low frequency voltage （0. 1 Hz）, it has some advantages such as shorter operating time and easier operation and so on. It can find most kinds of defects in XLPE power cable effectively, and dose no harm to the cable, so it has a good future.
