| Abstract: | Application of ANN(BP) used for transformer fault diagnosis is introduced. A new dissolved gas analysis model based on comprehensive characteristic input is set up. Its work fundamental principle, the sample classification method and the main calculation steps are presented. The result shows that network model can be used for transformer fault diagnosis and can improves obviously the diagnosis accuracy with self adapted training well. |
