The increasing complexity of today's power systems, and the growing numbers of power electronic devices that are being introduced, adds to the risk of power quality problems caused by harmonics. Non-linear loads into power systems, non-sinusoidal and distorted current waveforms, and voltage distortion have become more common, and these phenomena can lead to power losses and damage to equipment.
