Insulation Characteristics and Partial Discharge for the SF6 Gas Insulated Transformer

This paper describes insulation characteristics and partial discharge for the SF6 gas insulated transformer. The characteristic of gas insulated transformer and the degradation sequence of solid insulation under SF6 gas atmosphere were explained. The model electrode system of the types that the aramid papers were inserted between two sphere electrodes was prepared. The partial discharge tests were carried out to that system and the insulation characteristics were considered.
