At last, the temperature-rise of transformer is calculated using the temperature field method and the influence on DCmagneticbias to temperature-rise is analyzed.
According to the analysis results, the permission criteria of transformer DCmagneticbias is discussed and supplies reference for engineering practice and theoretical research.
