Abstract
The present paper describes a procedure for the online computation of the harmonics of symmetrical components based on the discrete Fourier transform (DFT) that uses all the information contained in the line-to-line voltages and line current. The proposed method has been tested experimentally to measure the harmonics of symmetrical components of a working three-phase induction motor for a wide interval of voltage source dissymmetry levels and for different load power levels.
