The paper presents the transfer function method used to study the turn fault characteristics behavior of a 100MVA, 220/66/11 kV transformer. The whole transformer is modeled by subdividing into 44 sections and represented by self-inductance, mutual inductance and capacitance parameters. The current in the neutral is computed by solving the network for applied impulse voltage. The transfer function is obtained for various turn faults simulated by reducing the number of turns in the electrical data for a given section. The location of the turn faults along the height of the winding is varied to study the characteristics behavior of the transformer by computing transfer function. Details of modeling, simulation of turn faults, computation of neutral current, transfer function are presented in the paper The effect of turn fault on the characteristic changes in the transfer function of the transformer is presented and discussed.
