SF6 for switch gear
SF6 for switch gear
(OP)
I was in a medium course for the whole of last week and the trainer mentioned that SF6 filled-switchgear is by far the safest compared to vacuum and air filled. But he could not explain to us why the gas is so good in quenching a flash. I did not need a chemical-engineer-hectic-type-of-an-answer, just the basic.

The vacuum technology in the US by far is more popular than SF6 for MV application. Engineering preference in other part of the world favor the use of SF6.
