Abstract

Basic electrical parameters directly affect the performance of the current transformer while some distribution parameters are difficult to calculate and measure. This paper establishes the general equivalent circuit model and series equivalent impedance expression of the current transformer. A prototype is made and tested with an impedance analyzer to obtain the series equivalent impedance. Combining the impedance expression and the measurement results, through calculation and fitting, the distribution parameters of the current transformer are determined.
用阻抗分析仪测量电流互感器配电参数的分析
电流互感器的基本电气参数直接影响电流互感器的性能,而一些分布参数的计算和测量比较困难。建立了电流互感器的通用等效电路模型和串联等效阻抗表达式。制作了样机并用阻抗分析仪进行了测试,得到了串联等效阻抗。结合阻抗表达式和测量结果,通过计算和拟合,确定了电流互感器的分布参数。
