---- Description text for this chapter - START
------------------------------------------------------------------------------------------------------------------------------>
Harmonic currents in the network affect the quality of energy and are at the origin of many disturbances as overloads, vibrations, ageing of equipment, etc ... This chapter covers the origins of harmonics, their effects, how to measure them, and presents the solutions to mitigate these harmonics.
