Resumen de Multi‐port equivalent scheme for multi‐winding traction transformers

Joseph El Hayek, Tadeusz Sobczyk

• Purpose – The purpose of this paper is to present a new type of equivalent scheme of multi‐winding transformers.

  Design/methodology/approach – An inventory representation of relations between currents and flux linkages has been interpreted as a multi‐port purely inductive circuit.

  Findings – An equivalent scheme in the form of a multi‐port circuit, and a method of its parameters determination from field computations.

  Research limitations/implications – Core losses are not considered in the multi‐port equivalent scheme.

  Practical implications – A new equivalent scheme could become a basic tool for modeling multi‐winding transformers.

  Originality/value – The introduced multi‐port equivalent scheme eliminates disadvantages of classical T‐type equivalent scheme of transformers.
