  • What is SF6 Circuit Breaker? Construction, Working Principle

    Gas System – The closed circuit gas system is employed in SF 6 circuit breakers. The SF 6 gas is costly, so it is reclaimed after each operation. This unit consists low and high-pressure chambers with a low-pressure alarm along with warning switches. When the pressure of the gas is very low due to which the dielectric strength of gases decrease and an arc quenching ability of the breakers is endangered, then this system gives the warning alarm.
