What is Neutral Current in Star-Star Transformers about?

This document analyzes an unexpected neutral current observed in a star-star transformer under steady state conditions. Using COMSOL Multiphysics software, the authors modeled the geometry, material properties, and magnetic circuit of a three-limbed transformer. The simulation showed asymmetrical magnetizing currents in each phase due to an asymmetrical core, resulting in a zero sequence current in the grounded neutral. The modeling accurately represented the phenomenon of zero sequence flux flowing through
