Abstract
The various criteria to identify the disturbances of the power transformer has been reported in this paper. They have been derived through EMTP simulations of internal faults, inrush and overexcitation for the model of 154/22.9[kV], 40[MVA], Y-Y three-phase power transformer. We also propose the algorithm which makes bpa Functions and infers the final decision from them based on Modfied Dempster-Shafer's rule of combination.
