Traction transformer 1 MV.A, superconducting, oil-immersed and medium frequency

Abstract

This paper deals with comparing 3 types of transformers - superconducting, oil-immersed and middle-frequency. These transformers can be used for locomotive as the main transformer. Weight, sizes and losses are introduced. The influence of eddy currents is describes by middle-frequency transformer. The article deals with magnetic properties of materials for higher frequency.
