Myth About SF6 Gas In Electrical Equipment· 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.Get Price
