Harmonics

Abstract

The chapter starts with an introduction of power system harmonics. It defines integer and non-integer types of harmonics. Then it describes the main sources of harmonics. After this, effects of harmonics in electrical machines and power system are discussed. Harmonic standards given by IEC and IEEE are referred. At the end different types of harmonic related indices are presented based on which power quality assessment may be done. © Springer Science+Business Media B.V. 2011.
