The shortterm discrete Fourier transform is used for the frequency characterisation of aperiodic waveforms. The paper presents the contribution of this transform to power quality assessment. Real measurements of the current consumed by an AC arc furnace are used to show the application of the shortterm discrete Fourier transform.
