Abstract :
The resolution to identify faulty insulator strings by detecting insulator corona current pulse was investigated in our laboratory. The influences of some facts on the detection resolution were also discussed, including the characteristics of insulators close to line, the resistance of faulty insulators, the locations of the faulty insulators, and the amount of insulators on the string. The results showed that the corona pulse analysis could be used for identifying faulty insulator strings in the laboratory
