| Abstract: | Based on a lot of flashover test results of polluted insulators in the artificial climate chamber, the Influence of atmospheric pressure on the flashover voltage of polluted insulators was analyzed systematically; the flashover performance of several kinds of polluted insulators under low pressure was presented; a simpler correction formula on the flashover voltage of polluted insulators in high altitued area and the formula of calculating the decrease rate of flashover voltage were proposed. These test results and the correction formulas can be used in the design of transmission line in high altitued. |
