Generated 3D and 2D mathematical models of field processes of electromagnetic energy conversion for operational and research modes of operation are developed. The technique of increasing the dimension of digital data for the characteristics of magnetization of electrotechnical steels has been developed. The generalized 3D and 2D field models of electromagnetic energy conversion are proposed, which are adapted to the circuit models for studying the operation of the transformer in idle and short-circuit modes. The parameters of the forward and reverse sequence of phases of the first harmonic of idling are determined, and a corrective technique is proposed that increases the accuracy of the calculation of idle currents and losses.  Product Description popup.authors popup.nrat_date 2020-04-02 Close
