The paper studies the different operating condition of transformer such as normal condition, magnetizing inrush, over-excitation, external and internal fault condition. We established power system model of (star-star) three phase transformer based on MATLAB/Simulink and calculate the differential current for the different operating condition of transformer. The differential current data help us to improve the performance of protection of transformer and also help to distinguish between the different operating conditions of transformer.
