Resumen de Investigation of load noise generation of large power transformer by means of coupled 3D FEM analysis
Purpose – This paper aims to present a 3D numerical analysis of the load noise generation associated with large, oil immersed three‐phase power transformers.
Design/methodology/approach – After studying the mechanical behavior of the winding structures of transformers, the results of coupled magneto‐mechanical simulations are presented.
Findings – An appropriate modeling strategy of the vibratory winding structures of transformers is necessary to reduce complexity and computational resources.
Originality/value – The presented model setup describes a fully transient, 3D coupled magneto‐mechanical simulation of the vibratory winding structure of large power transformers.
