The three ratios method of power transformer faults diagnosis based on decision tree with fuzzy logic propose in this study. The two major problems in the application of the IEC ratio method in transformer fault diagnosis are the lack of coding and the clear ratio range. Used the decision tree algorithm to solve the lack of coding problem. The fuzzy logic deals with the clear ratio range while ratio range displaced by the membership function. The simulation analysis of experimental data shown that the new method had more diagnostic accuracy, convenience and operability compared with the traditional IEC ratio method.
