摘　　要：配网架空线路接地故障因其故障电流小而难以准确定位,为此开发了一套架空线路接地故障选线定位系统,通过实时监测故障时刻线路产生的零序电流和行波波形,实现接地故障的快速定位。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 localization 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.
