Laboratory work in teaching basic three-phase electrical circuits

摘要

This paper describes a laboratory-based teaching proposal for the understanding of three-phase circuits at the undergraduate level of engineering degrees. The practical content of the proposed activities is oriented towards easing the students' understanding of the main concepts involved in three-phase circuits. The subject of three-phase circuits forms the basis for an elementary undergraduate course on circuit analysis. This work proposes simple and didactic laboratory lessons for the long-term understanding of many concepts involved in three-phase circuits which are often covered by only theory or simulation. The practical teaching proposed has been successfully implemented in the Industrial School of Engineering of the University of Seville and can easily be included in the laboratory curriculum of other Engineering schools.
