siemens sulfur hexafluoride Network Monitor in high electrical switchgear

The upgraded station has a special feature: for its high-voltage switches it uses clean air as an insulating gas - instead of sulfur hexafluoride (SF 6), which has been the standard for more than fifty years to prevent short circuits and arcs in substations.

  • SF6 gas in medium-voltage switchgear - Siemens USA

    In this issue, we discuss the use of SF6 (sulfur hexafluoride) gas in medium-voltage switchgear. SF6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses SF6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

  • Essentials of SF6 monitoring - Siemens USA

    Because SF6 has a global warming potential that is almost 24,000 times greater than CO2, it gets a lot of attention. And since the electric power industry is responsible for nearly 80% of the world’s usage, our industry has taken significant steps to reduce or eliminate the emissions from gas insulated switchgear.
