Recognition of Type of Faults in Power Transformer Using Dissolved Gas Analysis

This paper discusses dissolved gas analysis (DGA) methods, which involve the Duval Triangle Method (DTM), Duval Pentagon Method (DPM), Heptagon Graph Method (HGM), and ratio methods, such as the IEC, Rogers, and Doernenburg method, for identifying issues in power transformers through process. A particular method to recognize the type of issue in a power transformer DGA is the Duval triangle. The fault zone is indicated, and its position in a triangle with equal sides is depicted using the proportionate quantities of three fault gases. The most accurate method of evaluating the condition of a power transformer has been shown to be DGA. Six distinct kinds of DGA power transformer problems can be identified using the DPM, a DGA graphical interpretation technique. They provide a review of the advantages and disadvantages of each plan, which may help decide the DGA method that will finish the test analysis most effectively. It averts further harm to that particular transformer by eliminating early transformer breakdowns. Lastly, the results of the study and future studies will be discussed.
