Harmonic filters are an integral part of present-day electrical systems, which help combat the problems brought about by harmonic distortion. These filters are said to absorb and cancel out unwanted harmonics produced by non-linear loads like adjustable-speed drives and electronic devices. Doing that helps to stabilize and improve the quality of the electrical supply and therefore the energy cost incurred will be lower, and the operational reliability will be higher. To add on, the rising energy requirements across the world have also further escalated the need for harmonic filters for the efficient working of devices and maintaining the quality of power.
