Abstract

This study aims to diagnose the condition of distribution transformers using the dissolved gas analysis method, with a total dissolved combustible gas and Duval's Triangle approach. This study focuses on distribution transformers at Sultan Mahmud Badaruddin II International Airport in Palembang, with the aim of detecting disturbances and diagnosing the condition of transformers or internal damage that occurs in transformers based on the analysis of dissolved gases in the oil. The results of the total dissolved combustible gas testing indicate that the transformer experienced an increase in combustible gas levels in January and February 2025, indicating a “caution” condition and requiring further attention. In March and April 2025, the testing showed a decrease in dissolved gas levels, but the transformer temperature remained above the normal threshold. Through Duval's triangle analysis, it was found that in January and February, the transformer experienced a thermal fault at temperatures between 300°C and 700°C and experienced arcing. Meanwhile, in the March and April tests, the transformer's condition showed improvement with methane gas dominating, indicating that the transformer was operating more efficiently. Based on these analysis results, the transformer is still in good condition, and it is recommended to conduct regular monitoring of the transformer’s condition using the dissolved gas analysis method, as well as implementing preventive maintenance measures to enhance reliability and extend the operational lifespan of the transformer. Keywords: Dissolved Gas Analysis (DGA), Total Dissolved Combustible Gas (TDCG), Duval’s Triangle, transformer faults, transformer oil.
