Abstract: Feeder fault indicator in distribution network(FI) can improve the efficiency of inspection and repair. As an on-line monitoring method, it does a great help to improve the supply reliability. However, nowadays in FI, good and bad are mixed together. And the quality inspection before operating is less developed. So, it's necessary to develop an automatic and efficient detecting platform to manage the whole process. Firstly, the platform architecture is briefly introduced. Secondly, the detecting environment (high voltage and current) and capability are described in detail. Thirdly, an optimization solution to the whole process is put forward. And based on the typical case, its efficiency is analyzed. It shows that the proposed detecting platform of FI is cogent and reliable.
