Abstract :
This paper examines the proper application of induction machines when supplied by unbalanced voltages in the presence of over-and undervoltages. Differences in the definition of voltage unbalance are also examined. The approach adopted is to use NEMA derating for unbalanced voltages as a basis to include the effects of undervoltages and overvoltages through motor loss calculations.
