Myth About Sulfr hexafluoride Gas In Electrical Equipment

Apr 12, 2021 · 21. How much insulating gas (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 62271-203)
