摘　　要：变电站设计时,需要合理选择电流互感器的变比、规格与精度。重点分析和介绍了电流互感器二次侧绕组选择、变比选择、测量精度选择、准确阻值系数选择等有关问题。并对两相式和三相式电流互感器和零序电流互感器的选择进行了介绍,可供电气技术人员参考。During the design of substation,it is necessary to select consequently the current transformer ratio,specifications and accuracy. In this paper,the current transformer secendaly side winding,ratio,measurement accuracy,accuracy limit factor selection and other related issues were analyzed. Two-phase type and three-phase type current transformer and zero-sequence current transformer ＇s selection were introduced,which provides reference for electrical technician.
