  • Sulfr hexafluoride gas circuit breakers: a review of live tank and dead tank

    Sep 10, 2013 · At UHV level, the live tank circuit breaker requires 15 per cent of the Sulfr hexafluoride gas as compared to the dead tank breaker of the same voltage class. That means for same leak rate, the DTB has 600 per cent more impact on the environment. The dead tank breakers are manufactured as large castings which are bound to have porosity in it.
