Dissolved Gas Analysis of Transformer Oil | Electrical4U· Dissolved gas analysis (DGA) is the study of dissolved gases in transformer oil.It is also referred to as a DGA test. Whenever a transformer undergoes abnormal thermal and electrical stresses, certain gases are produced due to the decomposition of the transformer oil. When the fault is major, the production of decomposed gases are significant and they get collected in a Buchholz relay.
