摘要
对用跨步电压法查找电缆外护套故障过程中,在交叉互联箱处加电压时,互连箱地网电位升高导致故障点的不确定问题进行了详细分析,并提出了几种行之有效的解决办法。
If the testvoltage is applied on the cross- link box when step- voltage method is used to lo- cate the faultof outer sheath of electriccable,the potential rise of the cross- link box earthing grid will lead to some uncertainty of the faultlocation.In this article,the detailed analysis on this problem was presented,and the effective measures to solve this problem were putforward as well.
