The paper describes a digital system for measuring harmonic voltages and currents for analysis of inverter-fed induction motors. The new system allows high accuracy measurements by using the fast fourier transform in combination with suitable windows and interpolation algorithms in order to eliminate the spectral leakage errors. The system permits also accurate on-line measurements of power input and calculation of harmonic impedances so that a suitable motor model is obtainable.
