【摘要】 利用法拉第磁光效应可构成光学电流传感器（ＯＣＴ）。选择高Ｖｅｒｄｅｔ常数的传感材料，增加光束环绕电流的环路数是提高ＣＣＴ灵敏度的主要方法。采用比较测量法来消除温度对高Ｖｅｒｄｅｔ常数铁磁材料的影响，介绍了反向双环路结构传感头，并对其进行了实验测试。更多还原

【Abstract】 Optical current transducer (OCT) may be structured by utilizing the Faraday magneto-optic effect. To increase Verdet constant and the number of passes of light around the conductor are the main methods for increasing sensitivity of OCT. In this paper. the comparative measurement is taken to eliminate the influence of temperature when a high Verdet constant ferromagnetic material is used. Moreover, a dual-ring optical path structure is introduced. The experimental results of this sensing probe are presented.更多还原
