Abstract

This paper describes the effect of lightning impulse current on deterioration of ZnO blocks for distribution arrester. In this study. a multiple-lightning impulse current generator which can produce quadruple 8/20 ${\mu}s$ 5 kA is designed and fabricated, and total energy applied to the arrester block at each pulse is about 1,217 J. The experimental results indicate that the type of arresters are more vulnerable to deteriorate or damage at multiple-lightning impulse current.
