Abstract

SF6 gas is widely used as insulation media for gas-insulated switchgears (GIS) because of its excellent insulation properties such as high dielectric strength and arc quenching ability(1). However, since SF6 is a potent greenhouse gas, its use and emission must be decreased. From this point of view, a lot of studies on searching for an SF6 substitute have been conducted(1–4) and SF6/N2 gas mixtures seem to be the most promising and most thoroughly characterized gaseous dielectric media besides pure SF 6 (5) .
