In view of the intluence of ditterent capacitance combination contiguration of capacitor voltage transformer（CVT） on the voltage transmission in the voltage measurement

in this paper

the equivalent circuit analysis method is used and

on the basis of analysis of the influence of dividing capacitance difference on harmonic transmission characteristic

a kind of correction method with off-line simulation combined with bilinear interpolation method is proposed to eliminate the influence of the scattered dividing capacitance on each harmonic measurement result is proposed.The effectiveness of the method is verified by the analysis and calculation of the collected data at site

which has remarkable significance on the development of harmonic correction device based on CVT.
