This paper presents the discharge characteristics and economic feasibility of a Dry and a mixture gas in order to review alternative. From AC discharge experiment in an quasi-uniform field, it was found that the optimal mixing ratio which breakdown voltage and surface flashover voltage were the highest was 70/30 and that the pressure dependence on the breakdown voltage was higher than that of the surface flashover voltage in the Dry and the mixture gas. The mixing ratio (70/30) and the tendency of the pressure dependence were described in detail based on physical factors (impact ionization coefficient, electron attachment coefficient, secondary electron emission coefficient) involved in discharge mechanism and a electron source, respectively. In addition, the performance insulation and the economic feasibility of the Dry and the mixture gas were discussed so that Dry mixture gaswas more suitable than mixture gas to the alternative.
