The criteria of dissolved gas analysis in natural ester fluid
2012 IEEE International Conference on Condition Monitoring and Diagnosis, 2012In this paper, dissolved gasses of natural ester fluid were analyzed to suggest DGA criteria for transformer filled with natural ester fluid. Samples of mineral oil and natural ester fluid made to correspond to the ratios of the iron core, winding, insulating materials and insulating oil in a transformer were deteriorated for 1,600 hours in a 150°C ...

Dissolved Gas Analysis Results in Wind Turbine Transformers
2018 Australasian Universities Power Engineering Conference (AUPEC), 2018In recent years there have been issues of unusual dissolved gas analysis (DGA) results from routine testing of wind-turbine transformers. These are differences when compared to results from tests of standard oil-filled distribution transformers. This paper reports on a comparison of DGA test results for such transformers in Australian wind farms.The ...

Statistical Machine Learning and Dissolved Gas Analysis: A Review
IEEE Transactions on Power Delivery, 2012Dissolved gas analysis (DGA) of the insulation oil of power transformers is an investigative tool to monitor their health and to detect impending failures by recognizing anomalous patterns of DGA concentrations. We handle the failure prediction problem as a simple data-mining task on DGA samples, optionally exploiting the transformer's age, nominal ...

Dissolved gas analysis: It can save your transformer
IEEE Electrical Insulation Magazine, 1989The use of dissolved gas analysis (DGA) to monitor the in-service behavior of transformers is discussed. Sampling techniques are briefly considered, and two commercial hydrogen-in-oil detectors are described. The first allows the hydrogen concentration to be measured at intervals of a few hours by a portable gas collector that can be connected to ...

Categorizing transformer faults via dissolved gas analysis
2017 IEEE 19th International Conference on Dielectric Liquids (ICDL), 2017The industry at large is very proficient at diagnosing temperature within a power transformer via Dissolved Gas Analysis (DGA) and there are many tools to assist in this process, such as Duval's Triangle, Rogers Ratio, etc. However, identifying categorically where the overheating is taking place continues to remain relatively a mystery, for the most ...
