How to achieve “harmonic mitigation” ?
Several different solutions are proposed for Harmonic mitigation. The right choice is always dependent on a variety of factors, such as the activity sector, the applicable standards, the power level …. Several solutions are relative to Variable Speed Drives, as this type of electrical equipment represents a large part of the installed power in industrial installations and the most significant power harmonic current generators.

Re active energy and power harmonics explained with a car
How to understand harmonics & re active energy
Are you a driver? I am sure yes, therefore you will understand power harmonics right away
Imagine a straight road, flat, a perfectly smooth surface, a constant speed. Your car works well, consumes as little as possible, and can run indefinitely.
It’s like an electrical grid with a constant power without harmonics.
