Investigation of load noise generation of large power transformer by means of coupled 3D FEM analysis

Abstract

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.
