  • SF6 Circuit Breakers - Construction, Types and Working

    Jul 17, 2014Imperfect joints in the Sf6 Circuit breaker lead to leakage of the SF6 gas. Thus continuous monitoring devices are required. Arced SF6 gas is poisonous and should not be inhaled. While SF6 in its pure form is non-toxic, it does not support life and can, therefore, become a breathing hazard if it has collected. As it is heavier than air, it can
