摘要

本文提出了一种在谐振接地网中进行活动接地故障定位的方法。该方法基于非电网频率电流的额外电流注入，并在线路附近使用磁场传感器进行检测。该方法的优点是为操作人员提供了移动式接地故障定位装置。特别是在中压电网中，该方法为接地故障定位提供了一种有趣的方法。

Mobile earth fault localization by tracing current injection

In this paper the authors present an interesting method for mobile earth fault localization in resonant grounded grids. The method is based on an additional current injection with a non-grid-frequency current and detection with magnetic-field sensors in close vicinity of the line. The advantage of the presented method is that a mobile earth fault localization-unit for the operation personal is provided. Especially in medium voltage grids this method provides an interesting method for earth fault localization.
