Parameters Calculations of Transformer and its Performance Analysis under Transients

During this study, a high frequency model of transformer is proposed which is capable of eliminating the effects of transients applied on transformer. The conventional transformers use surge arrestors to remove these kind of effects, but they also transfers the effects of transients on secondary side which are hazardous for electrical equipment’s. Our proposed model is capable of eliminating the effects of transients without any major change in secondary voltage. This method is based on two-port network (T model) theory. The results of our method are examined and evaluated by computer simulations based on MATLAB.
