Harmonic Pollution on Power Systems - A Change in Philosophy

Abstract

Static power converters have increased in number and uses in the past decade, and there has been an increased use of static power capacitors for improving power factor. These two trends have set, the stage for possibly uncontrolled harmonic resonances on industrial power systems. Some example of some problems are given and some practices are recommended, in line with a new IEEE standard, that will minimize the chance of harmful resonant conditions.
