Transformers are most essential and consequential elements in electricity transmission and distribution. Therefore, in order to have a transformer working at optimum level, many researches and tests have been being performed. The goal of these tests and researches is reducing the amount of losses and extends lifetime of a transformer. During the conversion of the electricity in a transformer, some losses occur. These losses occur at windings and core of the transformer and they turn into heat. Transformers are widely used in almost all industrial application and is must for any basic industrial setup. As every machine, when running under normal condition is subjected to different kind of faults, the solution of which has to be carried out in advance to achieve best possible efficiency before actual use of the transformer. In the initial step, we go through the numerous papers which has worked on different parameters of transformer using FEM analysis. And the results of the same will be used in determining modelling of a transformer in the software using Finite Element approach. This method helps to develop accurate models of the machine under both healthy and faulty conditions. It also accurately calculates magnetic fields and related transformer design parameters for different types of transformers with completed geometry, which increases possibilities of improving the design during the planning stage (Before actual use of transformer). Using this method, analysis of Internal Insulation Design Improvements, Accurate Prediction and Minimization of No Load Loss, Internal Stresses at high frequency and faults like leakage reactance, internal winding stress etc. will be carried out. The analysis with the fault condition listed above will be simulated in FEM based software and the result will be compared with that of the transformer under healthy condition, which helps a great in knowing the worst possible condition under which transformer can be used. The design of the transformer carried out by the above method will be helpful to the industry in the sense that maximum possible efficiency and accurate calculation of magnetic field and stresses on windings can be achieved under worst possible conditions.
