As part of the master's thesis, we used finite element methods to analyze the existing load state in the transformer yoke beams. The yoke beams serve to provide the required compressive force of the core and windings, resulting in high mechanical loads. At the same time, the beams serve as the supporting structure of the active part of the transformer and enable movements of the active part in the process of transformer production. They are made of steel or special wood. In this thesis, we investigated the possibilities of using wood as a material for the production of yoke beams of more demanding transformers, for which higher loads occur than previously designed projects. We found that limit for using wood to make yoke beam is estimated for 25 tons of total mass of transformers.
