Porcelain Lightning Arrester

The series gap metal oxide lightning arrester is an important lightning protection device in AC transmission lines. When the tower arm potential rises, the series gap discharges and its lightning volt-second characteristic is lower than that of insulator, which can prevent insulator flashover and line trip.
