Abstract

PurposeThis paper aims to present a 3D numerical analysis of the load noise generation associated with large, oil immersed three‐phase power transformers.Design/methodology/approachAfter studying the mechanical behavior of the winding structures of transformers, the results of coupled magneto‐mechanical simulations are presented.FindingsAn appropriate modeling strategy of the vibratory winding structures of transformers is necessary to reduce complexity and computational resources.Originality/valueThe presented model setup describes a fully transient, 3D coupled magneto‐mechanical simulation of the vibratory winding structure of large power transformers.
