    • Calibration of burdens for instrument transformers 

      Autor: Draxler K.; Ulvr M.; Styblikova R.; Hlaváček J.
      (IEEE, 2020)
      The first part of this paper deals with the influence of burden accuracy on the errors of current and voltage instrument transformers. The requirement stated in the prepared standard, corresponding to a tolerance of burden ...

    • Determination of the Overhauser magnetometer uncertainty 

      Autor: Ulvr M.; Zikmund A.; Kupec J.; Janošek M.; Vlk M.; Bayer T.
      (FEI, Slovak University of Technology, 2015)
      Overhauser magnetometers are the basic instruments for scalar measurements; however, their accuracy is determined at the time of manufacture only. Because of various effects affecting the gyromagnetic ratio of the used ...

    • Precise calibration method for triaxial magnetometers not requiring Earth's field compensation 

      Autor: Zikmund A.; Janošek M.; Ulvr M.; Kupec J.
      (IEEE, 2015)
      A calibration procedure for calibrations of triaxial magnetometers is presented. The procedure uses a triaxial Helmholtz coil system and an Overhauser scalar magnetometer and is performed in the an Earth's field range. The ...
