Abstract:

Power transformer plays a vital role in our power system. Everybody is aware of the scenario consumers face once a power transformer goes out of order, particularly in our country. Owing to its demand, power transformer needs most up-to-date protection scheme. Overcurrent relay, gas relay and differential relay are the three important relay for power transformer protection. Faults are basically two types – through fault and external fault. There are a number of papers by different researchers in the country advocating different philosophies to design a numerical relay or software relay which can discriminate between a inrush and fault. This paper discusses the different types of inrush phenomenon in power transformer, except CT saturation, highlighting some of the methods to reduce it and detect it and simultaneously ventures to incorporate such a power transformer into the power system network and study fault pattern by the aid of world’s most popular environment, that is MATLAB- SIMULINK and also discusses some of its advantages.
