Applicative Analysis of Line Determination and Localization System for Ground Fault in Distributing Overhead Lines
The ground faults of distributing overhead lines feature small fault current,and thus are difficult to precisely localize.In view of this,this work made a preliminary attempt to develop a set of faulty line determination and fault locali-zation system.The system could real-time monitor the zero-sequence current and traveling waveform generated upon fault occurrence,thereby achieving prompt localization of ground faults.
