hv sf6 High pressure Disadvantage
2019/5/9Low density alarms and trips are pretty well standard on all of our HV SF6 apparatus; we also have high SF6 pressure alarms in select cases. I'm not aware of us using a pressure wave trip [63?] on any of our SF6 equipment. CR "As iron sharpens iron, so one

Furthermore, as SF6 is a potent greenhouse gas, it must not escape into the atmosphere. An SF6 gas density monitor warns operators of dropping levels that indicate contamination and/or leaks. WIKA's SF6 gas density monitors are temperature compensated and hermetically sealed to shield measurements from atmospheric pressure fluctuations and differences in mounting level.
