Research and application of fault linkage identification technology for power distribution

Distribution network supplying electric energy to end users is an important infrastructure related to the national economy and the people’s livelihood. Single-phase grounding faults often occur in overhead distribution lines. The shortcomings of the existing fault indicators are analyzed and the solution of fault linkage identification is put forward. According to technical transformation and experimentally running of FTU and fault indicator, it is verified that the solution can identify single-phase grounding fault rapidly and accurately.
