In previous tutorials, the examples provided were mostly for 2-winding transformers. In this tutorial, fault calculations for a 3-winding transformer are presented.

The MVa method results were verified using ETAP Modeling software. ETAP results proves that MVA Method for fault calculation is reliable. The complete tutorial can be downloaded below.
