基于TDR的故障电弧定位技术研究

Research on Technique for Arcing Faults Location Based on TDR

提出了一种基于TDR(时域反射)的故障电弧定位方法,设计了试验系统,并对设计原理、系统结构进行了说明。系统应用时间间隔测量技术构建了高精度的计时模块,具有较高的定位速度和精度,可以在故障电弧发生后定位出线缆故障点的位置。

A technique that locates arcing fault and its experimental system were presented. The paper illustrates the system＇s principle and structure. Time interval measurement technique was used in this system to build highprecision timing module. The experimental results show that the technique for arcing faults location based on time domain reflection（ TDR） can locate arcing faults position accurately and identify fault types of arcing faults concurrently.
