摘　　要：分析了电流互感器复合误差所涉及到的各个方面,从应用层面说明了互感器对复合误差的要求,进而介绍复合误差的直接测量法和间接测量法,文中提到的两种方法都是实用、易行的,并且叙述了电流互感器准确限值系数与二次负荷关系曲线的绘制方法,另外还列举出实例进行说明。This paper fully analyzes all the aspects involved in composite errors of current transformers and illustrates the requirements of composite errors for current transformers in terms of application. Direct measure and indirect measure on composite errors are put forword. The methods are practical and flexible, The paper also presents drawing method of relation curve of accuracy limit factor and secondary burden. Two examples are given on how to draw the curves.
