Advantages of sf6 emissions leakage

Advantages of sf6 emissions leakage

SF6 gas in a contained environment (such as switchgear) does not have any impact on the surroundings. Which means that the concern originates from the leakage of the gas while handling (installation or decommissioning of switchgear) or leakage throughout the operation of the equipment.
