摘　　要：分析了一种用于测量电力系统三相电流的光学电流互感器系统,用矩阵光学方法建立了既具有旋光效应又具有线性双折射效应的三相光学电流互感器系统的数学模型.对理论结果进行了仿真实验,指明了线性双折射效应对三相光学电流互感器系统在灵敏度、线性度、稳定性等方面的影响.从而说明。Three phase optical current transducer (OCT) is applied to the measurement of three phase current of electric power systems. A mathematical model is developed for the studying both the Faraday magneto optical and linear birefringence effect by using the method of matrix optics. The theoretical results are verified by an emulation test. The linear birefringence has an influence on sensitivity, linearity and steadiness of the system. The dominant factor that affects the system performance is the linear birefringence.
