Dissolved gas analysis - Wikipedia gas analysis (DGA) is the study of dissolved gases in transformer oil.. Insulating materials within transformers and electrical equipment break down to liberate gases within the unit. The distribution of these gases can be related to the type of electrical fault, and the rate of gas generation can indicate the severity of the fault.
