This work proposes a new method for diagnosis of incipient faults in power equipment with insulation oil. It consists on a set of interpretable rules extracted from the concentrations of the dissolved gases in insulating oil, and the relationships between these concentrations. Using a Decision Tree (DT) with changes in the size of the input attributes for obtaining rules, the proposed method: (i) allows the user to know the rules that generated the diagnosis, (ii) bypasses limitations common to other methods (e.g. the existence of "no diagnosis" regions, and the occurrence of more than one possible diagnosis) and (iii) the accuracy in diagnosis of DGA (Dissolved Gas Analysis) data available in the literature. The proposed method is compared...
