Numerical analysis for reducing negative impact of power transformers on the environment

Abstract

The goal of this paper is to present a methodology for numerical analysis of 3D numerical model of a transformer for reducing negative noise impact on the environment. The task is to map structural dynamics and vibrations of its selected parts. The main aim of this paper is to describe the numerical analysis of natural frequencies and demonstrate the impact of transformer construction in three-phase transformer core. The model taking into account the real arrangement of the device is solved numerically by the finite element method. All results are compared with experimental measurement on a real device.
