| Abstract: | Through the analysis of the mechanism about inrush current of Transformer,a new method,wavelet analysis,is applied to distinguish the inrush current and improve the transformer differential protection against the impact on of inrush current. By MATLAB simulation,the results show that the method eimprove the accuracy of distinguishing inrush current and has good application prospect and value. |
