Incipient fault in power transformer is closely related to isolation condition assessment. Dissolved gas analysis in transformer insulating oil is a well-known diagnostic technique. Produced gases serve as indicators of the type and severity of electrical stress. This paper presents a comparative study of multilayer perceptron and radial basis function neural networks for fault identification in oil-immersed power transformers. The neural networks are trained by using improved learning
