A circuit breaker in which the current carrying contacts operate in  sulfur hexafluoride or SF6 gas is known as SF6 circuit breaker. SF6 is a very good dielectric material which can resist high potentials.SF6 gas is used as the arc quenching medium Sulfur Hexafluoride (SF6) is an electro-negative gas and has a strong tendency to absorb free electrons. Whenever circuit breaker opens…
