Basic Transformer Knowledge - Interactive Video
This colorful, interactive training tool is an excellent primer on distribution transformers. It explains how transformers work using detailed schematics, cut-away drawings, and drag-and-drop exercises. Informative graphics explain transformer polarity, turns ratio, parts of transformers, how bushings are labeled, tap changers, and how to read nameplates. There’s a self-test at the end of each chapter.
