The simulation of electromagnetic processes for a loaded power transformer is performed. The influence on the parameters of the short circuit of the interphase mutual inductances of the windings is substantiated. The decomposition of a circuit-field model of a loaded power transformer into four coupled models is carried out. The validation of the simulation data with the experimental data proved the high accuracy of the calculations of the power transformer parameters for short-circuit modes and for symmetrical or asymmetric loading modes. The characteristics of a special multi-winding transformer in transient and stable modes with active, active-inductive and active-capacitive asymmetric load are obtained. The results of the simulation of the switching processes of the control stages of the winding stages for each individual phase were obtained.
