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.

Fault gas generation in ester based transformer fluids and dissolved gas analysis (DGA)
2008 International Conference on Condition Monitoring and Diagnosis, 2008Environmental concern, safety and sustainability of oil supply are the driving forces behind research into alternative dielectric fluids to mineral oil. Natural and synthetic esters, as the alternative fluids, need to be assessed under thermal and electrical fault conditions, and their performance and likely impact on the established diagnostic ...

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.

Proposals for an improvement in transformer diagnosis using dissolved gas analysis (DGA)
IEEE Electrical Insulation Magazine, 1995The diagnosis of oil-immersed transformers using the dissolved gas analysis (DGA) technique has been well accepted and widely used. IEC Publication 599 touches on the diagnosis of faults involving paper insulation based on the ratio of CO/sub 2//CO. It states that a fault involving paper insulation is probable when the CO/sub 2//CO ratio is 3 or lower;

In an electric power system, a power transformer is one of the most critical equipment and cannot be separated from possible abnormal conditions due to fault. Dissolved Gas Analysis (DGA) is a reliable technique for detecting the presence of a fault condition that just occurred in oil immersed transformer.

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

Understanding Dissolved Gas Analysis (DGA) techniques and interpretations
2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D), 2016The use of Dissolved Gas Analysis (DGA) as a method for determining the types of pending or occurring faults within power transformers has been in practice for many years. It has been proven that the generation of certain gases within a transformer is an excellent indicator that a failure is pending. DGA techniques have become so sensitive and accurate

Dissolved gas analysis (DGA) of partial discharge fault in bio-degradable transformer insulation oil
2007 Australasian Universities Power Engineering Conference, 2007Bio-degradable oil was commercially introduced as transformer insulation oil 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 bio-degradable oil as compatible as mineral oil.

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.
