Abstract

Transformers are one of the irreplaceable elements in the electrical system. During the working of the transformers, transformers are energized all day and these devices are subjected to a variety of stresses and electromagnetic forces. These stresses and electromagnetic forces can significantly affect the working of the transformer. The winding type of transformer has a great influence on the working of the transformer. The leakage reactance, flux leakage, voltage drop, and losses are also mainly affected by the type of transformer winding. Electromagnetic forces in the transformer are also influenced by the type of winding. In this work, a two-dimensional finite element transformer model has been used to investigate the electromagnetic forces in the sandwich winding transformer.
