摘　　要：磁光式互感器绝缘简单可靠,能显著降低成本,测量范围宽,无磁饱和,十分适用于高压和超高压系统中。为此,通过从模型元件的选择,到仿真实验,介绍了磁光式电流传感器的基本工作原理,测试了其灵敏性和暂态无饱和的特性。此外,磁光式电流传感器通用的数字化接口及对保护标准的兼容性,为其今后的广泛应用提供了便利。The insulation of the magneto-optical current transformer is simplified and reliable, which contributes to significant cost reduction. With higher broadband and no saturation, its improved measure performances are to satisfy the requirements of HV and EHV system. The basic theory, main element selection and simulating test of the magneto-optical current transformer are introduced in this paper. Meanwhile, its sensitivity and the characteristic of no saturation in transient condition are verified. The advantages on interconnection with digital equipments and compatibility with protection standards will facilitate its development in future.
