  • Electron production, electron attachment, and charge

    The electron attachment rate constants of 02, N20, and CF4 in N2 as well as H20 in Ar, N2 and CH4 were measured at various gas concentrations and E/N. It is observed that temporary negative ions due to electron attachment to H20 and CF4 are formed. The diffusion coefficients of electrons in air were measured in the E/N = 30 - 300 Td region.

  • Myth About SF6 Gas In Electrical Equipment

    Apr 12, 2021 · 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
