Our electrical machines three phase add-on pack allows students to understand the operation of three phase motors and to study AC.  The system contains a unit which houses several digital meters showing the current and voltage of machine being tested.   The unit also contains banks of resistors and capacitors which are switched on using the MIAC controller on the dynamometer system control panel, allowing the characteristics of the windings in the system to be changed with the speed of the machine.
