Abstract

DC bias of transformers will generate some important effects on power transformers. Furthermore it can bring about a malfunction of the power system. A simulation model is set up and the equivalent coupled electric circuit and magnetic circuit method is used to analyze the electromagnetic influence of DC bias. The method is testified by experiment results. Some results are concluded from the analysis of different DC bias conditions. The results are helpful to propose some methods to decrease the influence of DC bias.
