Abstract: The steep front surge voltage may occur in overhead distribution lines as a result of a direct lightning stroke or an indirect lightning stroke. Therefore, the steep front surge voltage has been taken into consideration, and the necessity of examining the discharge characteristics under the steep front impulse voltage came for protection of apparatus used overhead distribution lines. Moreover, in overhead distribution lines, outages due to contact with bird nests have become one of the serious problems in the recent years. Dielectric strength of the distribution line which bird nests exist is considered to be quite low compared with the distribution line which bird nests does not exist. Therefore, this research examined the creeping discharge characteristics on the surface of insulated wire when the steep front surge voltage occurs in distribution lines using the test line which imitated distribution lines which bird nests exist.
