Make/Break Contacts - In Power Circuit Breakers

In sf 6 circuit breakers, the same principle is employed, with gaz sf6 as the medium instead of air. In the “puffer” gaz sf6 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 insulating gas breakers have been developed for EHV (extra high voltage) transmission systems.
