SF6-Air leak rate CHINT

SF6-Air leak rate CHINT

Two substations were fitted with a sensitive sf6-gas trace analyzer and monitored during 9 and 13 months respectively, in two consecutive periods.sf6-gas gas was always present in the GIS surrounding air, at concentrations varying typically between 20 and ≈100 ppbv, but sometimes higher. These fluctuations were not due to the GIS leak rate changes but resulted mostly from the variations of the air exchange rate

    1980-1-1A similar enhanced diffusion of SF6 through common gasket materials has, to my knowledge, not been observed. This is supported by comparative leak tests done at Norsk Hydro Verksteder, where vessels show- ing 0.1 ~ H2 leak rate per year typically could show below 0.001 ~o SF6 leak rates.Author: R.S.
