摘　　要：在油田生产过程中，单相接地故障时有发生，因此，快速、准确地判断出故障线路，将对油田的高产、稳产起一定的作用。本文针对６ｋＶ线路单相接地短路故障线路判断间题，从理论上进行严格的分析、推导，给出可靠的理论根据；简要介绍６ｋＶ线路单相接地短路故障判断模拟装置及实验结果。Abstract In oil production,single phase faults in electric power line often take place,Theymav affect oil production. Therefore, the fault line mustb. detected quikly and accu-rately,which will make high and steady production possible. In accordance with theproblem of the fault line determination, strict analyzing and deducing are carried out andreliable theory basis are given. A detecting equipment are also introduced briefly andtest results are given.SUBJECT TERMS: single phase to earth,fault detection,filtering
