Abstract

To achieve higher power supply reliability, it is important to reduce lightning outages. In addition, the cost-benefit of lightning protection methods should be good. Many factors including the causes of lightning surge, the topology and insulation level of the power distribution lines should be considered to establish efficient lightning protection methods for power distribution lines. Furthermore, it is necessary to clarify the flashover characteristics of 6.6-kV power distribution insulators and examine the insulation coordination throughout the power distribution system. This study experimentally clarifies the flashover characteristics of 6.6-kV power distribution insulators currently used by considering polarity differences and pollution conditions.
