ABSTRACT

In order to research the influence of the capacitive voltage divider of capacitor voltage transformers (CVT) on harmonic voltage transmission in voltage measurement, based on the analysis of the influence of different capacitive voltage divider combinations on the harmonic transmission characteristics, an off-line simulation combined with bilinear interpolation method is proposed to eliminate the influence of the voltage-dividing capacitor on the results of each harmonic measurements by using the method of equivalent circuit analysis in this paper. And the validity of the method is verified by the analysis and calculation of the actual field collected data. The method is of great practical application value for the development of the harmonic correction device based on CVT.
