Harmonic voltage measurement error of the capacitor voltage

7.1 Harmonic measurement method for high voltage systems. We propose a harmonic voltage measurement method that is used exclusively for HVDC and UHVDC power transmission systems with paralleling AC/DC filters. In this method, the current i zH of the filter is measured and then decomposed using e.g. FFT technology.
