【Abstract】 For studying the influence of the external magnetic field on the current transformer, the model of current transformer is simplified, and the magnetic field of current-carrying conductor is assumed to be in horizontal distribution. Then, the relevant equations are established to determine the intensity of magnetic field. The comparison between the results by calculation and by experiment shows that the method is feasible. Finally, the technical measures to lower the influence are presented.更多还原
