| description | The invention relates to a capacitor voltage transformer dielectric loss measurement error correction method and device. The method comprises the following steps: constructing a dielectric loss measurement equivalent analysis circuit based on a dielectric loss equivalent circuit as a target circuit model; the target circuit model is used for quantitatively calculating dielectric loss test data of the capacitor voltage transformer under the influence of the interference branch; obtaining a target expression set corresponding to the target circuit model, and obtaining a first dielectric loss value and a first capacitance parameter corresponding to an electromagnetic unit in the capacitive voltage transformer according to the target expression set; and determining a dielectric loss measurement correction result as corrected dielectric loss data corresponding to a capacitive voltage divider in the capacitive voltage transformer according to test current parameter information obtained by measurement under a preset |
