Abstract
The most severe mechanical stressing occurs in Transformers when it is subjected to short circuit Since the current occurring through the windings are enormous. The problem does not yield easy solution due to the transient and dynamic nature of phenomena. It is very important to make the transformer in the way that when the short circuit condition takes place transformer should be able to withstand the electromagnetic forces with less or no effect The MATLAB simulation and FEM model is also shown for the better design of the transformer in this paper
