Trafag sf6 Calibration for transformers

Trafag sf6 Calibration for transformers

between the calibration of voltage transformers and capacitors at NIST. The voltage transformer calibration is of the direct null type, and the capac- itor calibration is of the comparative null type. In other words, the accuracy of the capacitance mea- surements ultimately depends on the uncertainty in assigning a value to a standard capacitor.

  • Gas density of SF6 and other gases - Trafag AG

    Sulphur hexafluoride (SF6) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties. It thus makes it possible to set-up complex and safe ­power distribution systems even in large cities. The insulation strength depends basically on the gas density.

  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF6 Gas Density Sensors, or by combining both principles, i.e.SF6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF6 gas density.
