Abstract – The Power transformers are backbone of electrical transmission and distribution system and it plays an important role in it. It changes voltages and current levels of the supply at every stages of power system according to requirement for smooth operation. The most important issue for transformer protection is to differentiate the inrush from fault currents. Distinguishing internal currents associated with faults from inrush currents in transformers is a vital component of a transformer protection method. Therefore, ensuring its protection is crucial to ensuring the power system operates steadily and consistently. One of the main reasons why the protection system malfunctions is the inrush current occurrence. Therefore, accurate and timely fault current and inrush current discrimination is essential for the power system to operate consistently and satisfactorily.
