PDF-Harmonics and IEEE Page of Introduction In an ideal power system the voltage supplied

In practi ce however conditions are never ideal so these waveforms are often quite distorted This deviation from perfect sinusoids is usually expressed in terms of harmonic dist ortion of the voltage and current waveforms Power system harmonic disto.
