Abstract
The dielectric strength of SF/sub 6/-N/sub 2/ is slightly higher than that of SF/sub 6/-CO/sub 2/ in slightly nonuniform fields encountered in gas-insulated switchgear (GIS) and gas-insulated cables, but the opposite is true in the cases of highly nonuniform fields and gas/film insulation existing in gas-insulated transformers. Experiments also show that the SF/sub 6/-air mixture with the SF/sub 6/ concentration being 0.8 can be used in cubicle type GIS, where the impulse dielectric strength of the gas mixture is apparently higher than that of SF/sub 6/ gas.
