Sustainable Alternatives to sf 6 Gas within MV and HV

Aug 03, 2018 · Be part of the chalenge: propose a solution! The challenge is aimed at finding alternative solutions to the use of sf6 gas gas as an insulating and/or interrupting medium within MV and HV equipment. Sulfur Hexafluoride (sf 6) gas is largely used as a dielectric and insulating material in the transmission and distribution equipment. Unfortunately, sf6 gas is also an extremely potent greenhouse gas with

NDIR SENSORS FOR Sulfr hexafluoride MEASUREMENT - smartGAS Mikrosensorik

Sulfr hexafluoride (sulphur hexafluoride) is a non-com- bustible and non-toxic gas. Throughout the world it is used primarily for insulating electrical high-voltage switching systems, transformers and cables. It is also used as an etching gas in semiconductor produc- tion and as a tracer gas in environmental simulations. The sensors measure either the purity and quality of the insulating gas in the systems or reliably detect minute sf 6 quantities in indoor air.
