The nonlinear load presenting in power system will cause the distortion of AC sine wave and generate harmonics

which seriously affects the accuracy of energy metering. According to the energy metering requirements of the new generation of intelligent electronic transformer substation for electronic voltage transformer

the working principle of the electronic voltage transformer based on the principle of coaxial capacitive voltage divider is analyzed in this paper

a mathematical model is established to analyze the transforming characteristics. The Multism12.0 simulation circuit is employed to simulate the frequency response characteristics of the electronic voltage transformer to the first until 13 th harmonics

and experiment is conducted for verification. Simulation and experiment show that the electronic voltage transformer can work in a broadband range from power frequency to high frequency

and is capable of accurately measuring harmonic components in power grid.
