Transformer Fault Diagnosis with the Duval Triangle and Heuristic Techniques

Applied Mechanics and Materials, 2014
Dissolved gas analysis (DGA) is an effective tool for detecting incipient faults in power transformers. The ANSI/IEEE C57.104 standards, the most popular guides for the interpretation of gases generated in oil-immersed transformers, and the IEC-Duval triangle method are integrated to develop the proposed power transformer fault diagnosis method.

Comparative Study of Duval Triangle with the New DGA Interpretation Scheme

2018
Fault diagnosis of power transformer for condition evaluation is being carried out by oil analysis for decades. The most efficient and easy way of condition evaluation of transformer is by evaluating the concentration of gases present in the transformer oil, done using dissolved gas analysis (DGA) over which several techniques are employed to predict ...

METODE RANDOM FOREST UNTUK KLASIFIKASI KERUSAKAN TRANSFORMATOR DAYA BERDASARKAN GAS TERLARUT PADA DUVAL TRIANGLE DAN DUVAL PENTAGON

JATI (Jurnal Mahasiswa Teknik Informatika)
Penyaluran energi listrik merupakan hal yang essensial dalam operasional komponen elektronik. Kinerja transformator untuk memenuhi kebutuhan transmisi bergantung pada sistem isolasi. Sistem isolasi berupa minyak transformator akan mengalami degradasi kualitas seiring dengan periode pemanfaatan alat.
