Fundamentals of Harmonic Distortion and Power Quality Indices in Electric Power Systems
Ideally, an electricity supply should invariably deliver a perfectly sinusoidal voltage signal at every customer location. However, for a number of reasons, utilities often find it hard to preserve such desirable conditions. The deviation of the voltage and current waveforms from sinusoidal is described in terms of the waveform distortion, often expressed as harmonic distortion.
Harmonic distortion is not new, and it constitutes at present one of the main concerns for engineers in the several stages of energy utilization within the power industry. In the first electric power systems, harmonic distortion was mainly caused by saturation ...
