高压电桥法探测电力电缆故障实测案例分析

Cable Fault Location Using the HV Bridge Method

对阻抗探测技术及其电缆故障经典探测法进行了深入分析,指出了基于电桥电路技术的电桥法的特点及其存在的问题。然后根据实测经验,针对隐蔽性较强的高阻故障,给出了基于电缆故障电桥法(经典探测法)的电缆故障探测技巧,并通过实测案例予以说明。

This paper made a deep analysis on the impedance location technique and the traditional cable fault location method,indicating the characteristics of the bridge method based on the bridge circuit technology and existing problems. Then,based on experiences and in terms of the high resistance fault that is hard to locate,the authors presented a cable fault location technique based on the bridge method（traditional method）and analysed the technique taking practical case as an example.
