Abstract :
Short-term customer deadlines, ambitious technical specifications and individual customer demands require high levels of precision and reliability in calculating the results for power transformers. Therefore, finite element analyses are increasingly utilized with initial design, design review and design optimization. The paper presents 3D finite element calculations with the intent of an optimization of winding support, core clamping system and tank wall shape regarding the electric field distribution in the winding support.
