A Mathematical Model for Close Coil Current Signal Analysis

Abstract:

The focus of this paper centers on the analysis of the close coil current signal in circuit breakers (CBs). The characteristic behavior of the close coil is analyzed by the electromagnet control law and a mathematical model is made to describe the dynamic characteristics of the close coil. Results of simulation and experiment are presented in the form of curves of the current of the close coil. The results show that the accuracy of the steady-state and dynamic-state model is satisfactory.
