Abstract

SF6 gas has widely been used as the insulating and arc-quenching gas for power apparatus such as gas insulated switchgear (GIS) and gas insulated bus (GIB), which contribute to realize compactness and high reliability of the apparatus. However, SF6 substitutes such as N2/SF6 gas mixtures are now in great concern to reduce the consumption and emission of SF6to the atmosphere,1 since SF6 is identified as one of the potent greenhouse gases.
