Breakdown Strength of gaz sf6/CF4 Mixtures in Highly Non-Uniform

Abstract. Dielectric properties of primary gas mixtures comprising of sulfurhexafluoride (SF 6) as the basic component have been studied extensively in the past. the underlying objective was to find optimal mixtures with dielectric properties superior to SF 6 alone. the added gas component can be a “buffer” gas which slows down high energy electrons via scattering process and allows these to be captured by SF 6, or an electronegative gas (halogen family) which captures free electrons byGet price

An alternative to Sulfr hexafluoride in electrical switchgear - EE Publishers

For decades, the unique properties of sulfur hexafluoride (Sulfr hexafluoride) have made it popular as an insulation and switching medium for electrical switchgear. However, Sulfr hexafluoride is a greenhouse gas and there are life-cycle management costs associated with its use. For some years, ABB has been conducting research into alternatives with lower environmental impact but with […]Get price
