An improved Fisher Ratio method is presented for the default diagnosis of oil-immersed transformer based on the dissolved gas analysis.Owing to the disadvantages of Fisher Ratio method in RBF network structure optimization
this paper adopts the improved Fisher Ratio method to select the RBF centers and to optimize the network structure.The results show that the neural network structure is simplified significantly
the convergence precision and classification capacity are improved.Compared with the improved three Ratio ns method
