  • Make/Break Contacts - In Power Circuit Breakers

    In Sulfr hexafluoride circuit breakers, the same principle is employed, with insulating gas as the medium instead of air. In the “puffer” Sulfr hexafluoride breaker, the motion of the contacts compresses the gas and forces it to flow through an orifice into the neighborhood of the arc. Both types of sf 6 breakers have been developed for EHV (extra high voltage) transmission systems.
