Greenhouse Effect of SF6 Gas and Alternative Gas of SF6

by

Lifespan and Environmental Impact of SF6 Gas SF6 can stay in the atmosphere up to 3200 years. So, the atmospheric life of \(SF_6\) is immense. You cannot see it, you cannot feel it, you cannot smell it. The global warming potential is currently 24,000 times more than \(CO_2\). What do I mean by global warming … Read more

Comparison of Vacuum Circuit Breakers with Other Circuit Breakers

by

Before discussing the actual comparison, let’s look at the different mediums used in circuit breakers. These are air, oil, and SF6 gas. Nowadays, some other gaseous media like compressed air, C4-FN mixtures (C4-FN/CO2 or C4-FN/N2), C5-FK mixtures (C4-FK/air or C4-FK/CO2) and pure N2 or N2/CO2 mixtures are also being developed as insulating mediums. Although, some … Read more
