摘要
绝缘故障是线缆的常见故障之一 ,当两个绝缘线芯之间处于低绝缘 (或不完全击穿 )条件下其定位技术更为复杂。本文主要讨论了线缆在这种条件下的绝缘故障定位的基本原理和方法 ,分析了提高定位精度的几种方法 ,并以实例介绍了实践中的测量技术。
Cable insulation fault occurs frequently. Its location is complicated especially when the dielectric strength between two adjacent cores becomes low (incomplete breakdown). This paper discusses the principle and method of fault location under this condition. Several ways to raise the accuracy of fault location are presented. Measurement techniques in practice are presented by case study.
