In a recent Power Panel Discussion, moderated by APC Media Managing Editor, Alan Ross , three distinguished experts—Edward Casserly from Ergon, Bruce Forsyth from Cargill, and Claude Beauchamin from TJ|H2b Analytical Services—shared their insights on the critical topic of transformer oils and fluids. As seasoned professionals with extensive backgrounds in electrical engineering, chemistry, and transformer technology, their collective experience provides a comprehensive understanding of the complexities associated with power transformers.

The discussion commenced with a focus on guiding new engineers entering the utility sector on selecting the appropriate transformer oil. Edward Casserly emphasized the historical success of mineral oils, highlighting their usage across various applications and voltage types. However, he underlined the importance of considering factors such as oxidation stability and pour points when making informed choices. Bruce Forsyth stressed the significance of fire risks, recommending natural esters for indoor placements or proximity to structures. Claude Beauchamin, representing TJ|H2b, acknowledged the industry's shift towards non-mineral oils, including synthetic esters, gas-to-liquid, and synthetic hydrocarbons.

A crucial aspect of the conversation revolved around the use of Dissolved Gas Analysis (DGA), a pivotal diagnostic tool in the utility industry. The experts addressed the lengthy process of updating the DGA guide, emphasizing the challenges faced by volunteers who contribute to standards development. Bruce Forsyth shed light on the complexity of interpreting DGA data, underscoring the need for reliable information to make informed decisions about transformer health.

In summary, the experts stressed the evolving landscape of transformer fluids, urging industry stakeholders to stay informed about the diverse options available. As power transformers play a pivotal role in energy infrastructure, making educated choices on transformer oils becomes paramount for ensuring longevity, safety, and optimal performance. This insightful discussion serves as a valuable resource for professionals navigating the intricate world of power transformers and their associated fluids.
