摘要：
The distributed optical voltage transformer measures voltage through the numerical integration, the choice of the integration points and weights rely on the distribution function of the electrical field. This paper presents a mathematical model of electrical field distribution in distributed optical voltage transformer through calculating electric potential. The simulation results show that the mathematical model reflects the main features of the axial electric field on the central axis of the distributed optical voltage transformer, which indicates that the method to solve the model is feasible. For a optical voltage transformer with a determined structure, the electric field distribution function can be directly obtained by the mathematical model, which could improve the accuracy of measuring the voltage through the numerical integration.
