Abstract
High voltage applications often use SF6 gas insulation and arc extinguishing medium. However, SF6 gas was specified as a greenhouse gas in the Kyoto protocol in 1997 and the manufactures of electric power equipments try to replace SF6 gas with another eco-friendly insulation medium. In this paper, the various insulation conditions of bus system of gas insulated switchgear were analyzed by finite element method and lightning impulse tests were performed to compare dielectric strength of each condition. Dry-Air and mixed gas with SF6 and Dry-Air, is considered as substitution of insulation medium and the epoxy coated surface of current carrying conductor as an addition of insulation material.
