Questions about sf6 Recovery and Filling testing

The usual methods are the use of electrochemical sensors or test tubes. How is the concentration of decomposition products determined in practice? The SO 2 concentration is generally used as an indicator for the overall concentration of decomposition products (coefficient approx. 1:4), measured in ppm v .

  • SF6 gas handling - DILO

    A service cart enables the recovery of the SF 6 gas from a gas compartment to a final vacuum of < 1 mbar. Thereby the gas flows automatically via dry and particle filters which effectively adsorb decomposition products and moisture from the gas. During the gas recovery process the SF 6 is stored either in gaseous or in liquid form. Furthermore, the air is evacuated from gas compartments after maintenance works.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020 · 21. How much SF6 (quantified in kg) can escape due to “normal” leakage? This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC
