摘　　要：简要介绍了智能电压降法、智能跨步法的工作原理,通过应用智能电压降法预定位、智能跨步法精确定点等方法对110,k V电力电缆外护层故障点查找的实际案例,验证了智能电压降法、智能跨步电压法对110,k V及以上电缆外护层故障点查找有效性。This paper introduces principles of intelligent voltage drop method and intelligent stride method. Then,realapplications of using the methods to find fault spots of protective covering of 110,kV cable were described. Through the casevalidation,it was proved that these two intelligent methods are able to find fault points of protective covering of 110,kVcable effectively and efficiently.
