Insulating gases (dielectric gases) are designed to quench, extinguish or prevent arcing when switching high voltage equipment. Switchgear, GIS and other compartments housing SF₆ and alternative insulating gases require a specific concentration/purity to ensure optimal operation and to ensure full quenching of discharges.
