초록

The surge protector is crucial power apparatus to guarantee the safe operation of power transmission of underground cable which can effectively restrain the overvoltage and inductive lightning stroke in power system. This paper describes the results of a study on the performance of ZnO varistors and surge protector for 154 kV underground cable. And, the influence of water tight and insulating performance was evaluated through such as surge protector of the armored design.
