Teaching three-phase power ... A low-voltage approach

Any electrical power systems course that includes demonstrations and/or laboratory exercises would benefit from a low-voltage three-phase power supply. Providing a low-voltage three-phase power supply allows classroom demonstrations and `hands-on' student participation in laboratory exercises without the danger associated with a 240 VAC system. Faculty and student surveys indicate that students would benefit from a `hands-on' approach and are more comfortable working with the safe low-voltage supply. Additionally, the flexibility and capabilities of the low-voltage three-phase power supply allow the instructor to implement demonstrations and laboratories that would not be possible on an energized 240 VAC system.
