This paper analyzes and designs the transformer fault diagnosis system based on dissolved gas analysis (DGA) database in which DGA data is managed by the Oracle database. The fault diagnosis module includes the single analyzing item and the Integrated analyzing item, such as, improvement three-ratio method, grey relational entropy, fuzzy clustering, artificial neural networks, and so on. They reduce...
In the paper, a transformer dissolved gas analysis in oil (DGA) fault integrated diagnosis system based on Oracle is developed, and its modules are introduced. Fault diagnosis of transformer is based on three-ratio-method, grey relational entropy, fuzzy clustering, Artificial Neural Network, featured by its analytic hierarchy process to integrated analysis, so as to perfect existing diagnosis methods...
