Determination of Per-Phase Equivalent Circuit Parameters of Three-Phase Transformer Using MATLAB/Simulink

In this article, Simulink is used to implement the open and short circuit tests of three-phase transformers. With most universities switching to online methods of teaching in the wake of the coronavirus pandemic, this article outlines how to perform the transformer tests for undergraduate electric machines classes using Simulink. The aim is present the virtual experiments whose results lead to determination of the approximate per-phase equivalent circuit model of a three-phase power transformer. The article will be of help for students who cannot attend conventional practical laboratory sessions due to COVID-19 standard operating procedures restrictions or shortage of equipment and will be a great supplement for those who can.
