【Abstract】 The eigenvalues characterizing the fault position in both solid insulation and bare metal part of power transformer is studied in this paper. The integrated diagnosis by use of the principle of fuzzy set is carried out. The influence of the contents of single substance such as carbon monoxide, carbon dioxide, furfurol and ethylene on fault position of power transformer is analyzed, and it is tried to determine where the fault occurs, i.e., in the solid insulation part or in the bare metal part, by judging with the value of the membership function of every substance to the location of fault position. The practical applications indicate that this method is simple and the result of judgment is correct.更多还原
