I was tasked to look for at least two design experiments to illustrate the industrial applications of AC machines. We are going to perform the design experiments in our laboratory classes. Please help me. Anything simple could do.
You could demonstrate that as the load on a three phase induction motor or transformer, increases, so too does the power factor. This is something that is important to demonstrate as it will lead to the correct size motor or transformer, being installed. A second demonstration could be showing that as the mechanical load on a three phase motor, increases, the motor draws more current and the slip speed percentage, increases slightly. You can use a prony brake to apply more load in both of these demonstrations. You will also need a power factor meter, a watt-meter and a tachometer.
