要約(英語): This paper describes an experimental study on multiphase flashover in 6.6kV medium voltage line in Japan. The experiments simulate a direct lightning strike to the top of concrete pole of the distribution line. A flashover occurs from a metallic arm to a phase wire. Most of single-phase flashover in non-grounded lines is naturally recovered due to low fault current. Therefore, a study on multiphase flashover is very important to establish a rational lightning protection design for medium voltage lines. Influences of parameters such as the combination of insulators and crest value of applied voltage on the multiphase flashover are discussed. A solid core insulator and a pin type one, which are normally used in 6.6kV lines in Japan, are used in the experiments. Measurements of fifty percent flashover voltage and voltage-time characteristic are carried out in this paper. This paper discusses an influence of different insulation level insulators on the reduction of two-phase flashover using the experimental results.
