Abstract: In allusion to the flashover fault tripping events of composite insulators in 110 kV overhead transmission lines in a certain area of northwest region, the electrical performance and size of composite insulators after the flashover were carried out tests.This paper analyzed the weather situation and geographical conditions when the faults happened.It is concluded that the cause of the fault is the wet flashover of composite insulators caused by rainwater, and the preventive measures and treatment suggestions are put forward to prevent similar failures from happening again.
Key words: overhead transmission lines; composite insulators; flashover fault
