  • Comparison Between Vacuum and SF6 Circuit Breaker

    Aug 29, 2018The 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.

  • Panel discussion: The pros and cons of using SF6 gas in

    Sulphur hexaflouride (SF6) gas has been used in MV and HV switchgear for many years. It is said to be highly toxic and a potent greenhouse gas. It is used because of its excellent electrical insulation properties, but recently some switchgear companies have suggested other solutions. In our virtual panel discussion we asked some specialists […]
