The present work made a preliminary attempt to explore the use of feature matrix and decision tree in the iden-tification of disruptive discharge faults with respect to GIS voltage transformers.The method was designed to extract the gas characteristics of GIS voltage transformer encountering disruptive discharge fault for the construction of feature matri-ces,and to generate a decision tree using the ID3 algorithm for the classification of the feature matrices,so as to realize fault identification.The proposed method achieved in the experiment an identification accuracy of 95.8％ for the GAS-VT disruptive discharge fault.
