Abstract

The DGA (dissolved gas analysis) is an effective method to detect abnormalities in transformers through the gases released due to transformer failures. Interpretation is necessary to determine the type of failure by processing the dissolved gases in the insulation oil of the transformer as a result of the DGA testing. This study employs Fuzzy logic combined with applicable standards to interpret the dissolved gas analysis results for identifying the transformer's condition. Using Roger's Ratio and Duval's Triangle interpretations with Fuzzy logic, it was found that transformer AV04 experienced D1 failure (low energy discharge), AV05 had D2 failure (high energy discharge), and AV06 encountered D1 failure (low energy discharge)

Additional Information:	Analisis gas terlarut merupakan metode efektif untuk mendeteksi ketidaknormalan pada transformator melalui kandungan gas yang muncul akibat kegagalan transformator. Interpretasi diperlukan untuk mengetahui jenis kegagalan yang terjadi dengan mengolah data gas-gas terlarut pada minyak isolasi transformator hasil pengujian DGA. Penelitian ini menggunakan logika Fuzzy yang dikombinasikan dengan standar yang berlaku untuk menginterpretasikan hasil analisis gas terlarut guna mengidentifikasi kondisi transformator. Hasil menggunakan interpretasi Roger's Ratio dan Segitiga Duval menggunakan logika Fuzzy ditemukan bahwa transformator AV04 mengalami kegagalan D1 (low energy discharge), AV05 mengalami kegagalan D2 (high energy discharge), dan AV06 mengalami kegagalan D1 (low energy discharge).
