Myth About SF6 Gas In Electrical Equipment

2019-4-25 · 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
