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.

When professionals want to manage an electrical system in a new installation or after retrofit or extension of an existing installation, it is important to consider the Harmonic currents emitted by the non linear loads connected to the distribution system.
The non linear loads or products producing harmonics can be as example, for industrial equipments: welding machines, battery chargers, variable speed drives for electrical motors, uninterruptible power supplies, or for office equipments or household appliances: TV sets, fluorescent lighting, light dimmers, etc…
