Transformer design in the undergraduate power engineering laboratory

A power engineering laboratory experiment on transformer design is described. In the experiment the student design, builds, and tests a single-phase transformer to specifications provided by the instructor. From initial test results, the transformer is redesigned, and the new design is tested. Standard open and short-circuit tests are then performed to develop a circuit model for the transformer. The model is then used to predict the transformer´s operation, and the predictions are compared with the values measured in the laboratory
