Abstract :
Probabilistic and time-frequency aspects of time varying waveforms in power systems are considered with reference to DC arc furnaces and adjustable speed drives using line commutated inverters. These loads are characterized by waveform whose spectral components are time-varying in amplitude and frequency. The problems of understanding and assessing their waveform distortion is taken into account. Some considerations on the most adequate techniques for the spectral component representation and calculation are effected
