As one of primary causes of switch trip in distribution feeders
extended fault from user lower the power supply reliability of distribution networks.This paper analyses the necessity of installing protection on the beginning of sub-feeders
and presents a method of installing fuse protection on sub-feeders.It is of great significance to decrease fault-trip times
assure reliable operation and lessen inspection workload for distribution systems.
