A set-up for the measurement of the frequency response of voltage measurement transformers under actual waveform conditions is presented. It is based on the two steps procedure that makes use of high voltage gas insulated capacitors and a digital bridge. It allows for calibration using distorted waveforms, with a fundamental tone at medium voltage level and a harmonic content up to 10% and 10 kHz. A practical application to a frequency calibration of a voltage measurement transformer is also presented.
