High voltage switchgear relies on SF6 gas to insulate live parts and quench arcs. If the gas density drops, so does the dielectric strength, and that puts equipment and people at risk.
An SF6 gas density monitor watches each gas compartment and trips alarm or lockout contacts before density falls too far. For HV switchgear it is one of the most important protective devices on the kit.
Trafag manufactures mechanical gas density monitors, electronic gas density sensors and hybrid devices for SF6 and alternative insulating gases. Browse the full range to find the right fit for your switchgear.
