摘要：
The paper discusses numerical models of single-phase superconducting transformers. The addition of mathematical relationships made it possible to determine the average and effective current in subsequent periods, and to calculate the amount of heat that is released in the windings when switching the unloaded transformer to the full voltage of the supply network. The waveforms and impulses of the inrush current of 21 MVA transformers with superconducting windings were calculated and compared.
