摘　　要：提出了一种全新的用一路光和一套检测系统实现电力系统三相电流同时测量的三相光学电流互感器。用矩阵光学的方法建立了基于法拉第磁光效应的正相光学电流互感器的数学模型，对理论结果进行了仿真实验，指出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，证明了系统的可行性。A novel type of three-phase optical current trans-ducer system which is applicable to measure three-phasecurrent of electric power system is developed, the systemworks with one optical path and a set of detect equipment.The mathematics model of three-phase optical current trans-ducer based on faraday magnetooptic effect is established byusing the method of matrix optics. The theoretical resultsare verified by simulating test, the linear bireftingent effecthas influence on sensitivity, linearity, steadiness of the svs-tem. Analysis and simulating results have showed the feasi-bility of the system.
