Comparative Analysis of Options Indicators of Submersible Electromechanical Systems’s Three-Phase Group Transformer

Improving the characteristics of electrical systems is possible when developing and using spatial structures of electromagnetic devices. Group compact transformers consist of several single-phase toroidal transformers which are characterized by the convenience of being embedded in enclosures of a limited diameter, but have a number of disadvantages. An analysis of the features and optimization comparison of the components of a three-phase group transformer of a cylindrical installation of submersible electromechanical systems is carried out. Replacing a traditional toroidal single-phase electromagnetic system with a radial electromagnetic system with a three-core twisted magnetic circuit leads to an improvement in the mass-cost and energy values of a single-phase transformer.
