SF6 room Analysis for HV MV

Aug 23, 2009Comparison of the SF6 And Vacuum Technologies. The most important characteristics of the SF6 gas and vacuum-circuit breakers, i.e., of SF6 gas and vacuum as arc-extinguishing media are summarized in Table-1.. In the case of the SF6 circuit-breaker, interrupters which have reached the limiting number of operations can be overhauled and restored to 'as new' condition.
