摘　　要：基于电光晶体的泡克尔斯效应和磁光玻璃的法拉第效应，提出一种新颖的光学电功率传感系统。该系统主要将电光晶体与磁光玻璃串联使用，可以直接获取电功率传感信号。研究了该传感系统的传感原理，并分别对纯电阻性和感性负载进行交流电功率传感实验，其非线性误差分别低于1．3％和1．4％。on Pockels effect in electro－optic crystal and Faraday effect in magneto－optic glass, a new optical electric power sensing system is presented in this paper. The electric power signals can be directly obtained by connecting a voltage－dependent electro－optic crystal with a current－dependent magndeto－optic glass. The mechanism of the sensing system is analyzed. The experiment on measuring AC electric power is completed, and its non lindrity errors are separately lase than 1. 3% and 1. 4% for the resistive and inductive loadimpedance.
