Abstract
Induction motors has wide application in industries because of its rugged, easy operation and requires less maintenance characteristics. Besides the fact that they are reliable, they are exposed to different types of faults from which Unbalanced voltage supply is one such external fault. This fault can bring about issues like excessive warming due to huge amount of losses, over-voltages, mechanical oscillations, audile noise and so on. Here, the impact of unbalanced voltage supply on the induction motor performance is studied. The analysis has been done to find the unbalanced voltage effect on the induction motor current and torque. For this, 16 different voltage unbalance cases have been picked with 8 different voltage unbalance type and 2 different voltage unbalance factor (VUF). Matlab Simulink is the tool used here for performing the experiment and its analysis.
