SF6 insulated Calibration for HV MV

SF6 insulated Calibration for HV MV

Aug 18, 2019This technique would be applicable for low, medium and high voltage VI's. Both technique need to be built-in to the VI from the start. At now no practical way to introduce the gauges to VI's after production. The gauges could be used when the VI is in SF6 with the appropriate calibration.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020Basically there is no difference as both applications use the SF6 in gas-tight compartments with negligible leakage rates. In general the MV (up to 52 kV) use pressures close to atmospheric pressure in sealed pressure systems. Low pressure and small size result in little gas quantities of only some kg.
