    Abstract

    An automated transformer dissolved gas analysis evaluation system based on the recently released IEEE Standard C57.104-2019 for mineral oil-immersed transformers is implemented and its outputs demonstrated. The system includes diagnostic capabilities using the Duval Triangles 1-4-5 and Rogers Ratio method. In addition, a Health Index derived from the above Standards is proposed as a compact, yet informative metric for tracking transformer health. Finally, some of the challenges in developing such an implementation are highlighted.
