The electric field intensity distribution of the electronic resistive voltage transformer is significantly influenced by the earth

the surrounding charged body and the grounding object. Distributed capacitance exists between the high voltage lead or the high voltage end wire of the resistance voltage divider and the earth. All these factors mentioned above influence the technical performance of the voltage divider. Therefore

electric field intensity shielding of the resistive voltage transformer is necessary. This study analyzed the influences of the resistance characteristic and the distributed capacitance on the performance of the voltage transformer via equivalent circuit

and also analyzed the electric field intensity distribution of the resistance voltage divider by the software Ansys. As a result

a 10 kV voltage transformer shield and a voltage divider were designed and passed the related testing.
