Abstract

We carried out the dry flashover test and wet flashover test, after the artificial contaminant damage work, in order to inspect the validness of the anti contaminant equipment as a suspension insulator (ceramic material, EPDM), LP insulator, arrester and COS. As a result of experiment, the dry flashover voltage value of the damaged equipment with the salinity was similar to the normal equipment even if the equipment is damaged with the salinity. But when the humidity was high under the damaged state, the flashover voltage value of some distribution equipment was low under the 20 kV.
