Engineering application of an external signal source fault indicator and fault location system

In order to improve the efficiency of fault finding and fault handling, a fault location sys- tem with external signal source fault indicator was applied. This paper expounded the technical princi- ple of the fault location system, analyzed the fault detection criteria of the fault indicator. Combined with the actual project, the problems in the field application were analyzed, and an engineering application evaluation method of the fault indicator based on the index analysis was presented, finally the application effect was evaluated.
