Research on Fault Location of Transmission Line based on Magnetic Detection Technology

针对传统的输电线路故障定位方法存在缺陷,基于行波法的系统结构复杂且成本很高,阻抗法容易受到线路参数的影响且偏差较大。设计了一种基于磁探测技术的输电线路故障定位系统,与传统方法相比,该系统具有经济、可靠和准确等优点。

In view of the defects of traditional transmission line fault location method,the system structure based on traveling wave method is complex and the cost is very high,impedance method is easy to be effected by line parameter and the offset is big.This paper designs a fault location system for transmission line based on magnetic detection technology.Compared with the traditional method,the system is economical,reliable and accurate.
