Role of surface to volume ratio of zinc oxide arrester blocks on the energy absorption capability

The functional life of a zinc oxide arrester block is largely dependent on its energy absorption capability. This capability is an important performance characteristic of a lighting arrester which leads to enhanced reliability of a surge protection system. An arrester block is usually cylindrical in...
