Calculating the Mutual Induction Coefficient for Leakage Fluxes in the Equivalent Circuit of a Three-Winding Transformer
Three methods for calculating the mutual induction coefficient for leakage fluxes, which serves as a parameter in a proposed new equivalent circuit of a three-winding transformer, are presented. Examples are presented that illustrate the application of these calculation methods for simulation problems and welding transformers. The patterns of the magnetic leakage fields of these transformers illustrate the main concepts used in determining this coefficient.
