n this paper the magnetizing process of the magnetic core is'analyzed and a new mathematical model of magnetization curves is given, which can give accurate results of calculations for every parts of the magnetizing process. The simulating calculations of transient performance of the current transformer and the inrush current of the power transformer are made and the results are satisfactory as compared with the recorded wave forms from the real system experiment. Therefore this model can be used to analyze the effects of the magnetizing process on the operations of the power system.
