Abstract
This paper presents the investigation results ofvoltage harmonic transfer accuracy problems through voltagetransformers which are widely used in power quality monitoringsystems in medium and high voltage grids. A simplified lumpedparameters circuit model of the voltage transformer is presentedand verified by simulation and experimental investigations. Anumber voltage transformers typically used in medium voltagegrid has been tested in the conducted electromagnetic inter-ference frequency range up to 30 MHz. The obtained resultsconfirm that broadband voltage transfer function of the voltagetransformer usually exhibits various irregularities which areprimarily associated with voltage transformer winding parasiticcapacitances.
