Abstract
The high dielectric strength of SF6 gas is exploited in a number of applications including gas insulated substations (GIS). It is expensive, however, and there has been an ongoing interest over the years in using mixtures consisting of cheaper buffer gases such as air and nitrogen with added SF6 to produce a comparatively cheap mixture with a dielectric strength almost as good as pure SF6. The author looks at the effects of additives on the mechanism of breakdown and on point/plane gaps
