High voltage transformers generate significant heat during operation, which must be effectively managed to prevent overheating and damage. To study and optimize the cooling of transformer windings, we use Computational Fluid Dynamics (CFD) simulations. These simulations focus on finite volume meshing, heat reduction, and identifying hot spots. CFD simulations work by dividing the transformer windings into many small cells using a technique called finite volume meshing. This detailed breakdown allows precise calculations of fluid flow and heat transfer. Finer mesh resolutions provide more accurate results but require more computing power, while mesh optimization focuses computa-tional resources on critical areas where overheating is most likely. The primary goal is to efficiently reduce the heat generated within the transformer windings. Identifying and managing hot spots, areas with the highest temperatures, is crucial for transformer reliability. CFD simulations map out these hot spots, which need special attention to prevent damage. Understanding how temperature is distributed throughout the transformer helps in designing systems that keep all areas within safe limits.
