| Abstract: | A novel method on synthetic diagnosis for insulation fault of power transformer is put forward, in which the effective information from electrical tests and analysis result of the dissolved gas in the oil can be fully utilized. In this method the fault diagnosis is divided into two parts, i.e., the identification of physical sign and the confirmation of faulty position, then the diagnosis methods applied to them are separately optimized. Thus, the accuracy of synthetic diagnosis is effectively improved. |
