Abstract

In this article, we will consider the benefits of transformer digitalisation, which requires yielding actionable information within a reasonable turn-around time of the digital twin. The simulation turn-around time, that is, the time needed to set-up, run, and post-process the results, is important in both design exploration during development and in forecasting scenarios during operation. A pole-mounted, 100-kVA distribution transformer is used to show how simulations can be used to generate reduced-order FEA based models for predicting transformer loss (core, winding, and stray), dielectric, and temperature hotspots.
