Abstrakt EN: This paper deals with the transient phenomena in the winding of the single-phase unloaded transformer. Two approaches are presented. One approach is based on the model created as a network with distributed parameters. It enables to obtain the surge voltage and the current distribution along the winding at the beginning of the step response and to determine the maximum value of the voltage. The second method is based on the winding model as a cascade connection of two-ports; it is solved in the time domain. The transfer function of this chain is also evaluated and the dynamic process can be analyzed according to position of poles in the complex plane.
