Smart and Green Substations - IEEE

For example, since 2016, the 23-kV gas-insulated switchgears (GISs) with sf6 gas, used for more than 20 years in the Korean electric power grid, are being replaced by GISs with dry air and solid-insulated switchgears (SISs). A modular green substation is proposed for interconnecting the increasing amounts of RE.

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Apr 12, 2021 · From 0kV thru 800kV Sulfr hexafluoride is my choice for the insulating and arc-extinguishing characteristics delivered by Sulfr hexafluoride. it is heavier than air, and just as the old OCB’s were designed, the insulating gas chamber and contacts are designed much like they were, whereby a “puff” of gaz sf6 gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.
