Dissolved gas analysis (DGA) of vegetable oils under electrical stress [PDF]
2017 International Conference on High Voltage Engineering and Power Systems (ICHVEPS), 2017 Dissolved gas analysis (DGA) is often use by theutility companies to monitor the health and to detect any faults of their transformers. The concentration and proportion of various gases dissolved in the oil are used to indicate whether there is an electrical or thermal fault within the transformer. A lot of data have been published in the literature on

Multiple incipient fault classification approach for enhancing the accuracy of dissolved gas analysis (DGA) [PDF]
IET Science, Measurement and Technology, 2019 Multiple incipient faults are practically known to exist in transformers. They tend to produce suddenly changing ratio limits in ratio‐based methods or oscillation of fault location in graphical methods. In consequence, the energy associated with them lies in‐between low and high severity single faults.
