摘　　要：介绍了基于磁光材料的法拉第效应的系统工作原理,采用块状磁光材料与集磁环相结合的方法制作的传感头,稳定化光源和A/D转换等实现方法。实验结果表明:该电流传感器系统在30 kV工作电压下可实现对30 kA脉冲及交流电流的测量,为高压下大电流测量提供了一种有效的方法。The fiber-optic current sensor system based on the Faraday effect of the magneto-optic material was introduced. The realizing method included a system designed with the sensor head which combined a nubbly magneto-optic material with a ferromagnetic concentrator ring, a stable illuminant and A/D converter. The experimental result indicates that this current sensing system can measure the pulse current and alternating current of 30 kA with the voltage of 30 kV, and offered an effective method in the measurement of high voltage and current.
