In the modern world, power is a necessary element of daily life. The bulk of ordinary items have some kind of power. We must make use of the most advanced energy technology to deliver power to people in a secure and economical manner. The loss increases because of harmonics increasing the circuit's current flow's RMS value. Many problems with the electricity grid have arisen as a result. The loads as well as the entire distribution system may be affected by harmonics. Moreover, harmonics may harm delicate machinery and appliances in a commercial or industrial setting. Harmonic dysfunction does not always become apparent right away, and it might even be mistaken for standard equipment wear and tear. 

Harmonics is a key aspect of a power system since they affect the quality of electricity and the performance of equipment. High harmonic levels may induce overheating of components, hence decreasing the device's lifespan. An ideal power source produces harmonics that corrupt the pure sinusoidal wave. The production and operations of a corporation are hindered by harmonic distortion. The following are some business effects of harmonic distortion:
