g3, the Sulfr hexafluoride-free solution in practice | Think Grid

Switzerland This project using g 3 was delivered and tested onsite in March 2018 at an Axpo site in Switzerland. It features four bays of 3-phase encapsulated 123 kV GIS and can operate, just like SF 6-GIS, down to -25°C. It was the very first project featuring a circuit-breaker using g 3 as arc quenching medium.
