In order to solve the problem of the dynamic error analysis of the current transformer, firstly, the mathematical model of the current transformer is established. Secondly, based on the working principle of the current transformer, the causes of the dynamic error of the current transformer are studied. On this basis, the important parameters affecting the dynamic error of the current transformer are analyzed theoretically. Thirdly, different dynamic test signals under complex working conditions are selected. After that, a composite error analysis algorithm is proposed to give the dynamic error quantitatively. Finally, the influence of the above parameters on the dynamic error is given, and the relationship between these parameters and the dynamic error is discussed. The results show that, according to the composite error analysis algorithm adopted in this paper, the dynamic error of different dynamic test signals under complex working conditions can be calculated effectively and the specific influence of each parameter on the dynamic error can be obtained.
