| Abstract: | In this paper,the exciting current waveform and harmonic of transformer was tested with or without DC bias so as to analyze their changes.Then the magnetization curve of transformer was calculated under DC bias,based on Jiles-Antherton transformer model.Using the data of magnetization curve,the changes of instantaneous magnetic field distribution,flux density harmonic and the waveform of exciting current could be obtained through three dimensional finite element calculations.Among the above,the waveform of ... |
