A method of describing processes in cold-rolled electrical steel is proposed, which reproduces the dynamic hysteresis loops in core legs and yokes. A method of accounting for magnetic fluxes in nonmagnetic medium which makes the transfomer model reversible is described. The model developed is illustrated by calculating inrush current produced by subsequent energizations of three-phase bank consisting of four-limb transformers.

Abstract
A method of describing processes in cold-rolled electrical steel is proposed, which reproduces the dynamic hysteresis loops in core legs and yokes. A method of accounting for magnetic fluxes in nonmagnetic medium which makes the transfomer model reversible is described. The model developed is illustrated by calculating inrush current produced by subsequent energizations of three-phase bank consisting of four-limb transformers.File in questo prodotto:
