Gas Insulated Switchgear leak rate for powergrid

Gas Insulated Switchgear leak rate for powergrid

Meanwhile the electrical company, Eaton, has shown that older switchgear can leak as much as 15% for the full life cycle of the product while newer switchgear have lower leak rates. In 2017, SF6 emissions in Europe were the equivalent of 6.73 megatons of CO 2 which equals the greenhouse gas emissions for 1.3m cars for a
