How and why do you do a load test on an induction motor?

This was a good experiment in terms of it was to show us the direct result of the effect of increasing the load current on the motor power factor. It showed that the higher the current the better the power factor. The Electrical Supply Board desire a high power factor for installations within Ireland and penalise those which do not meet required standards as they see poor power factor as a wasteful loss of energy. It also showed that there are two ways in which the rotating magnetic field could be used to provide the rotating motion.
