Introduction to Power Quality and Harmonics
Harmonics in power systems refer to the sinusoidal components of a periodic waveform having frequencies that are integral multiples of the fundamental frequency. If the fundamental frequency is denoted as ''f'' (usually 50 or 60 Hz for power systems), the 2nd harmonic is 2f, the 3rd harmonic is 3f, and so on. The fundamental frequency, or the 1st
