The purpose of the work is to develop models and synthesis methods of static electromagnetic devices parameters. The analysis of transformers constructive features is performed and transformation of geometrical structures parameters for multicomponent transformers active parts in a tuple of physical and geometrical structures which are supplemented by set of parameters and characteristics of mechanical electric and magnetic properties with their materials is offered. Methods of circuit-field calculations of electromagnetic processes in active parts for power three-phase transformers I-III dimensions have been further developed. For the first time, a conjugate circuit-field model of electromagnetic processes is proposed, which combines integro-differential equations of circuit model for phase currents and flux couplings with differential equations in partial derivatives for vector magnetic potentials. New design solutions for compensation third harmonic components of magnetizing currents and magnetization currents components of phases reverse sequence for transformer are offered.
