探讨振荡波测试系统在配电电缆局部放电测定位中的应用

本文介绍了振荡波测试系统（OWTS）进行电缆局部放电测试和定位的工作原理，提出了使用防晕电极消除电缆始端沿面放电干扰的方法，分析了补偿电容在短电缆测试中的降频作用。并结合数百条电缆的测试经验，以两条典型测试电缆为例，阐述了振荡波测试系统在电缆局部放电测试定位中的现场应用和数据分析过程。

Study of the Application of Oscillating Wave Test System for Partial Discharge Test and Positioning in Distribution Cable

This article describes the working principle of oscillating wave test system for cable partial discharge test and positioning,to eliminate the interference from surface discharge along the cable start end,the method of the using of anti-corona electrode is proposed,this article also analysis the role of the down-conversion of compensation capacitor in the short cable test,and takes two typical test cables as an example. Combined with hundreds of cable testing experience,it expounded the data analysis process and the application of oscillating wave test system for partial discharge test and positioning in cable.
