In the thesis the direction of transformers improvement is further developed with structures and forming contours conversion of electromagnetic systems elements. The method of optimization calculations and comparative analysis of the active part variants on the basis of nondimensional technical level indicators and universal relative geometric controlled variable is further developed too. The mathematical models of non-traditional electromagnetic systems are developed. The possibility of technical level indicators im-
proving of three-phase transformers based on spatial magnetic cores and optimization calculations for one of the criteria of mass, active power losses or cost minimum of active part is shown. The methodology of calculation allows optimization of transformers variants using integral capital cost indicator that contains components of developed mathematical models for individual criteria optimization.
