  • Limiting SF6 Gas Emissions by Optimization of Design

    2016-2-17In service, the emission rate, for actual designs is about 0.3% for HV equipment (for voltage above 52 kV), i.e. 10% during the life of the equipment, and lower than 0.1% for MV equipment (from 1 to 52 kV – especially for sealed for life equipment). So huge and specific efforts have been made during the last years [2].
