Fluxes of electromagnetic field energy in HTSC transformers

The transfer of electric power in an HTSC electromagnetic system is considered using the Poynting vector. An analysis of the process of transfer of electromagnetic field energy in HTSC transformers with and without an iron core is given. It is shown that the power of an HTSC transformer increases when its magnetic core is made from amorphous electrical steel. Schemes of HTSC transformers with a localized magnetic field are given with cylindrical and disk symmetrical interleaved windings providing the cost-saving process of transfer of large electromagnetic energy at a high degree of its uniformity and improve the factor of nonuniformity of electromagnetic flux density.
