Abstract This paper reviews a basic data of the surface discharge characteristics for teflon resin in not only pure N₂, N₂:O₂(80[%]:20[%], I-Air) and N₂:O₂(60[%]:40[%]) mixture gas as environment-friendly insulation Gas also SF?. Used electrodes are Knife to Knife. With the changing distance of electrodes and pressure, we can find it, surface discharge voltages and surface dielectric strengths, respectively. Surface discharge Voltages of I-Air are more higher than the other N₂/O₂ mixture gases. Moreover, we can obtain that the surface dielectric strengths of SF? are two times about I-Air, approximately.
