Abstract

Many factors are required to be considered when determining efficient lightning protection methods for power distribution lines, including the causes of lightning surge and the topology and insulation level of the power distribution lines. This study experimentally clarifies the flashover characteristics of 6.6-kV power distribution insulators currently being used by considering polarity differences and polluted conditions. Furthermore, this study proposes an approximate formula that is based on the sparkover model to calculate the flashover characteristics of 6.6-kV power distribution insulators, and contributes to the improvement in insulation coordination throughout power distribution systems.
