Derating of induction motors operating with a combination of unbalanced voltages and over or undervoltages

Pragasen Pillay, Peter Hofmann, Marubini J. Manyage

Open publisher page 150 citations

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.
