Abstract With the improvement of industrial society, high quality electrical energy, simplification of operation and maintenance, and ensuring reliability are being required. Also we request an urgent change from SF? gas to an environment-friendly gas insulation material. In this paper, the experiments of breakdown characteristics by pressure and gap change of N₂/O₂ mixture gas through a GIS (Gas Insulated Switchgear) model were described. This paper reviews basic data of the surface discharge characteristics for Teflon resin in not only pure N2, N₂:O₂ mixture gas as being focused on environmentally-friendly insulating gas, but also SF?. Also, insulation characteristics by breakdown voltage and surface discharge voltage of N₂:O₂ mixture gas in the experimental chamber were studied.
