Abstract: At the energization of transformers strong saturation and very high (inrush) currents may result which often last tens of seconds or even a few minutes. Because of the slow attenuation, the inrush phenomenon may be examined by phasor representations in the harmonic domain, i.e. as a quasi steady state phenomenon. In this paper harmonic domain analysis is used, including the d.c. component and even harmonics, to obtain a sequence of steady state "images" which constitute the complete picture of the inrush phen…
