Based on the application of fault location technology in urban distribution network

this paper compares the advantages

disadvantages and application ranges of three fault location technologies in distribution network

introduces the development process of fault indicator and the principle of common fault indicators

and gives some application suggestions

considers that the fault indicator is the most practical fault location technology in distribution network at present

and the research accuracy of short-circuit fault

especially grounding fault

is higher

at last

mainly introduces the application of fault indicator in fault location of distribution network

and gives the application suggestions and matters needing attention in the end.
