In this paper, the arc resistance tests of synthetic resins were carried out in various gas insulators such as N_2, CO_2, SF_6 and air, and the effects of species of gas and their pressure on arc resistance were investigated. The effects of various gases on the process of arc deterioration were also discussed. The AS TM D495 standard arc resistance testing method was used. The maximum pressure of the gas was 4 ata. The increase of arc resistance in gas such as N_2 and CO_2 was noticed. In the high pressure gas, several cases appeared: the case with an abrupt decrease in arc resistance, the case with a V-or N-letter type curve against the increase in gas pressure. The increase of gas pressure did not always result in the increase of arc resistance. The arc resistance remarkably increased SF_6 under 2-4 ata. except silicone glass. There are no inherent difference in the arc resistance in gas insulators between D. C. supply and A. C. supply.
