  • Abstract
    This paper deals with the impact of nonsinusoidal currents and voltages on the losses of power transformers. Conventional methods for the determination of the hottest spot temperature are used to predict the loss of life of transformers supplying loads which inject nonsinusoidal currents. Derating curves are explained and a practical example is presented.
