ATMOSPHERIC CONTAMINATION ON HIGH VOLTAGE INSULATORS AND A STUDY TO IMPROVE CONDITIONS

Abstract

Comparative studies of leakage currents, dry and wet flashover of contaminated insulators with similar readings taken on new insulators are made. The possibilities of removing the encrustation on insulators are studied. The presence of the electrical field on the insulator has an effect on the deposition of impurities and some means are suggested to avoid or reduce the amount of deposits.
