Understanding the vibrational characteristics of power transformers in the design and monitoring stages has attracted the attention of many researchers recently. The analysis of vibration characteristics of a power transformer is presented in this paper. The structural dynamic response analysis is included in an enhanced finite element modeling. The main goal of this simulation is to look for indicators related to different structural elements for vibration monitoring purposes. This research also aids in the understanding of some interesting vibration behaviors in transformers, allowing for a virtual simulation of the transformer rather than costly factory tests.
