A method describing processes in cold-rolled steel and reproducing dynamic hysteresis loops in certain core components (legs and yokes) is proposed. A method that takes into account magnetic fluxes in a nonmagnetic medium that makes the transformer model reversible is described. Transients initiated by sub-sequent energizing of a three-phase group of four-limb transformers in a 500-kV network are simulated.

Abstract
A method describing processes in cold-rolled steel and reproducing dynamic hysteresis loops in certain core components (legs and yokes) is proposed. A method that takes into account magnetic fluxes in a nonmagnetic medium that makes the transformer model reversible is described. Transients initiated by sub-sequent energizing of a three-phase group of four-limb transformers in a 500-kV network are simulated.File in questo prodotto:
