浅析振荡波测试在配电电缆局部测试中的应用

Application of oscillating wave test in the local test distribution in cable

该文介绍振荡波的测试系统来进行关于电缆局部的放电测试以及定位的原理,表明了运用防晕的电极来消除电缆的始端沿面的放电的干扰的手段,分析电容在测试中的降频功能。并且根据实际的测试经验,用两条典型电缆做测试为例子,叙述了关于振荡波的测试系统在电缆的某些部分放电的测试定位里的现场使用以及数据分析的过程。

This paper introduces the test system oscillation wave of principle about cable local discharge test and positioning,demonstrates the use of electrode corona to remove the cable end interference along the surface discharge method,function of reducing frequency analysis of capacitor in the test.And according to the actual test experience,do the test as an example with two typical cable,describes the process of discharge in some part of the cable test location test system of vibration wave in the field and data analysis.
