【Abstract】 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.
