Mobile earth fault localization by tracing current injection
暂无分享,去创建一个
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.
