develop sf6 gas switchgear tester

SF6 is used as insulation gas in gas-insulated switchgear (GIS) today since the technical performance of SF6 perfectly matches to the technical requirements. The drawback of SF6 is the high global warming potential (GWP) of about 23.500 (100 year time horizon, CO2 equivalent) which is subject to discussion in the EU and in other countries.
