Comparative Analysis of New Methods for Defect Type Recognition by Dissolved Gas Analysis

The article deals with the authors' most recent methods of defect type recognition based on the results of dissolved gas analysis. The analysis of diagnostic criteria used by these methods for defect type recognition is performed. The results of comparative analysis of reliability of defect recognition of different types with the considered methods are given. It is found that recognition reliability for all analysed methods is approximately at the same level, but there are differences in recognition reliability of different methods in relation to defects of different types.
