Highly professional SF6 insulated load switch check for leaks

Nov 17, 2011When switching is done in a SF6 Gas insulated switchgear, arching will occur. This is because there is a high impedance on the breaker switch when the switch is opened and high voltage current tries to flow through the impedance. The arching release immense heat and SF6 gasses will quench the arching in order to prevent it from spreading.

  • Safety by design: solid insulated technologies challenge

    SF6 switchgear falls under three categories: closed pressure systems, controlled pressure systems, and hermetically sealed systems. Among these, hermetically sealed systems do not allow maintenance, and manufacturers claim that SF6 leaks are very limited during the equipment’s lifetime. However, with all three systems, SF6 is
