Abstract

Instrument transformer accuracy testing by the method based on integration of DFT and virtual instrument concept, composed of standard hardware (osciloscope, PC) and specific software is outlined. The structure of the realized virtual instrument for accuracy test of current transformer by DFT method is shown. The method has experimentally verified and compared with measurements made with the classical complex Hohle compensator.
