The ProLAB provides the most modern and cost effective approach to teaching the theory and practice of Electrical Machines. Operating from a single phase supply, producing its own dc and 3-phase, there is now no need to provide a dedicated laboratory for testing Electrical Machines; the experiments can be performed in any classroom. The ProLAB can be used as a traditional stand-alone system, with its comprehensive range of modules, but its full potential is only realised when used with the powerful DIANA software package in a networked environment. No longer is it essential for each group of students to have an individual test bench and range of machines. Not only can the ProLAB be used for demonstration but each student on the network can have access and control of the hardware to perform their own tests supervised by the instructor. Familiarisation with the equipment and post experiment analysis of data and report writing can be performed outside the laboratory. In addition DIANA includes comprehensive simulations for each machine. Safety, to protect both the equipment and the student, is paramount and to protect the environment power is returned to the grid when the system is acting as a load.
