    Mar 01, 2019The SF 6 concentration in an electric power system is usually 99.8%, which means that the detection of the trace gaseous decomposition is operated in a pure SF 6 buffer gas rather than in N 2 or air environment as usual. Several SF 6 physical constants such as the density, thermal conductivity, molar mass, specific heat and viscosity strongly differ from those applicable to N 2 or air.
