Power is a crucial component of life in the modern world. We are always surrounded by things that are powered in some way. To provide affordable and secure electricity, we must use the best power systems. Harmonics boost the RMS of the current flow in the circuit and hence increase loss, which has led to several issues with the power systems. Harmonics may have an impact on the loads as well as the entire distribution system. Delicate appliances and equipment in your industrial or commercial facility might potentially be harmed by harmonics. In other cases, the existence of a harmonic breakdown is not immediately apparent and cannot be distinguished from the normal ageing of the appliance. 

Since it affects both the quality of the electricity and how well the equipment works, harmonics are an important subject in a power system. High harmonic levels might lead to component overheating and reduce the device's lifetime. Harmonics cause the pure sinusoidal wave generated by a perfect power source to be warped. Harmonic distortion impairs a company's ability to produce and run its activities. Here are some harmonic distortion's financial effects.
