Abstract In this paper, Simulink software in Matlab is used to simulate and analyze the remanence of current transformer core under different influence factors and verify that the remanence of current transformer core has its changing law under different influence factors. The results show that the remanence in the current transformer core changes obviously under the influence of the transient aperiodic component, the breaking time of the fault current, the time constant of the primary circuit, the amplitude of the fault short circuit current and the impedance of the secondary load. The stronger the influence factors, the greater the remanence will be.
