It is an excellent insulation gas, e.g. in medium and high-voltage switchgears of electricity grid operators. However, as SF6 works in gas-insulated switchgears, it is highly susceptible to one natural enemy: moisture! Once present in the gas compartment, it weakens the insulation properties of SF6 many times over.People also askWhat are the properties of gas insulation?What are the properties of gas insulation?The insulator properties of the gas are controlled by the combination of electron attachment, electron scattering, and electron ionization. Atmospheric pressure significantly influences the insulation properties of air. High-voltage applications, e.g. xenon flash lamps, can experience electrical breakdowns at high altitudes.Dielectric gas - Wikipedia

For maintenance purposes, SF6 must be evacuated from gas insulated switchgear. To do this, the gas is pumped out into portable recovery systems (see photo), where it is then filtered and fed to the compressor, which compresses it. The final pressure is generally 40 barg. Once cooled, the gas can be stored in a liquid state.Missing:delixiMust include:delixiSF6 Breaker Testing And Maintenance - Industrial Tests
