Abstract

Dissolved Gas Analysis (DGA) is a method to identify the type of failure in a transformer by assessing the amount of gas contained in the transformer's insulating oil. DGA has several methods of analyzing and identifying failure types based on the type of gas dissolved. However, with large amounts of data this method becomes difficult and requires expertise in graphical failure detection. This research aims to improve the diagnostic accuracy of transformer failures by implementing the K-Nearest Neighbours (KNN) algorithm on each conventional DGA method namely Roger Ratio, Duval Triangle, Four Gases and Duval pentagon in classifying failure types with various distance metrics namely Canberra, Euclidean, and Bray Curtis. A total of 822 data samples were used to train and validate the model. The results of transformer failure diagnosis show that Duval Triangle, Four Gasses, and Duval Pentagon are the most effective methods in diagnosing transformer failure types. Classification results with the KNN algorithm are strongly influenced by the selection of parameters used to determine each type of class, the highest accuracy in classification with the KNN algorithm is obtained by the Duval triangle method with an accuracy rate of 98,17%.
