Myth About sf6 gas Gas In Electrical Equipment

Apr 12, 2021 · 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.
