sf6 switchgear testing for 121kv

However, during arcs or in the event of switchgear failure, SF6 and its by-products can be released into the environment. Imperfect 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.

    Oct 23, 2020Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of
