A Study into the Impact of the Supply Voltage on the Mains Supplied Induction Motors

It is very important that the electrical power which the appliances are subjected to, needs to be at their rated value. This is because the performance of the appliance is optimum at its designated value. Unfortunately, in the UK and in other parts of the world, the electric appliances are supplied with voltage higher than their required value which is wasting a considerable amount of energy, deteriorating the performance of the electric appliances and is proving very costly for electricity consumers. This problem of overvoltage and the effect of voltage optimization on the domestic appliances will be investigated in this project. In order to determine the effects of the overvoltage, several experiments at different supply voltages and one using a Voltage Optimizer will be carried out on one domestic freezer, which is one of the most commonly used domestic appliance. For every experiment, the motor parameters such as temperature, power consumption, current drawn etc. will be measured. In the end, the parameter values for all the experiments will be analyzed in order to determine the benefit of voltage optimization for domestic appliances.
