  • SF6 paper | Hrushaabh Mishra - Academia.edu

    C. Insulation PerformanceAir and CF4 are chemically inert gases. SF6 is usually diluted with these two gases in order to reduce the release of SF6 and the associated environmental impact. However, the dielectric strength of a mixture of SF6 with Air or with CF4 is always lesser leaser than that of pure SF6.
