Analysis Oil Condition of Transformer PT-8801-A by Using the Method TDCG, Rogers Ratio, Key Gas, and Duval Triangle: A Case Study at PT. Perta Arun Gas

Journal of Renewable Energy, Electrical, and Computer Engineering, 2022
The power transformer would have happened disturbanced that can cause a failure at a transformer. For this condition needed to maintenance power transformer, one of which is by analyzing transformer oil by using the TDCG method. This analysis is carried out to determine the diagnosis of faults in the transformer.
