  • Replacement for SF6: GEnew 'g3' gas - Page 1

    Nov 14, 2019 · SF6 has an awesome global warming potential, true, but it is also very, very dense. My recollection of SF6 is that it notoriously pools in the low parts of structures and in such spaces presents a danger of asphyxiation, ~6kg/m^3 at STP, where nitrogen is around 1kg/m^3 under the same conditions.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020 · 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 62271-203) For sealed for life MV equipment a range below 0,1 % per year is common.
