Evaluation of Distribution Network Transformer Dissolved Gas Analysis (DGA) Data
PES T&D 2012, 2012IEEE Standard C57.104-1991 IEEE Guide for the Interpretation of Gases Generated in Oil-Immersed Transformer outlines the guidelines and procedures applicable to large power transformers. This paper describes how Consolidated Edison applied this standard to underground network distribution transformers.

Dissolved Gas Analysis (DGA) of Mineral Oil Under Thermal Faults With Tube Heating Method
2017 IEEE 19th International Conference on Dielectric Liquids (ICDL), 2017Dissolved Gas Analysis (DGA) is one of the most effective methods in condition monitoring and fault diagnosis of oil immersed transformers. To facilitate the DGA data interpretation, investigation of fault gas generation under laboratory simulated faults using immersed heating method is often conducted.

Dissolved Gas Analysis (DGA) of Natural Ester Insulating Fluids With Different Chemical Compositions
IEEE Transactions on Dielectrics and Electrical Insulation, 2014This study presents experimental results of the application of the dissolved gas-inoil analysis (DGA) technique to natural ester insulating fluids. The investigations covered two common types of transformer faults, discharge and overheating, and four different commercial insulating oils, one mineral and three natural esters: Biovolt A (from corn oil ...

2017 International Symposium on Electronics and Smart Devices (ISESD), 2017
This paper proposes the implementation of A3S information fusion algorithm to interpret Dissolved Gas Analysis (DGA) based on Doernenburg Ratio. A3S (Arwin-Adang-Aciek- Sembiring) is a method of information fusion derived from Bayesian Inference Method (BIM) to handle multi-hypothesis multi-indication problem for single observation time.

A Review of Dissolved Gas Analysis Measurement and Interpretation Techniques
IEEE Electrical Insulation Magazine, 2014 Dissolved gas analysis (DGA) is used to assess the condition of power transformers. It uses the concentrations of various gases dissolved in the transformer oil due to decomposition of the oil and paper insulation.

Fault severity determination in transformers using dissolved gas analysis(DGA)
2015 Annual IEEE India Conference (INDICON), 2015Severity is the intrinsic property of transformer faults. DGA of gaseous species evolving from power transformers due to electric and thermal stresses distinguishes between types of faults. No information about severity is provided by the DGA based techniques.

Dissolved gas analysis (DGA) of arcing faults in biodegradable oil insulation systems
2008 International Symposium on Electrical Insulating Materials (ISEIM 2008), 2008Due to environmental concerns regarding the use of mineral oil, biodegradable oil was commercially introduced as an alternative for transformer insulation in 1999. Since then, the usage of this oil in the power industry has steadily increased and a lot of researches have been in progress to make biodegradable oil as compatible as mineral oil.

The collection and analysis of gases in an oil-insulated transformer were discussed as early as 1928 [1]. One of the signs of fault diagnosis in a transformer is the rapid growth of gases during a failure of an oil-filled transformer. It should be noted that these gases are dissolved in the oil. As a result, some faults could be identified by analyzing
