dc.description.abstract Abstract The phenomenon of magnetic hysteresis effect of the core material of a transformer plays an important role when representing the transformer in a simulated environment. Input-output behavior of a transformer is critically correlated with the magnetic properties of the core material which is influenced by the magnetic hysteresis effect. To analyze the magnetizing characteristics of the core material of a transformer, it is required to develop a mathematical model for simulating the hysteresis phenomenon. As the outcome of this research, reliable representation of magnetizing characteristics of a three-phase transformer core, without considering any core material related parameters, a test based mathematical model is simulated. Mathematical model, which capable of producing magnetic characteristics for any given voltage level is designed by conducting two tests separately for a single phase transformer and three limbs of a three phase transformer. In the scope of this research, magnetizing characteristic model is developed using Matlab Simulink. Test data required to develop the proposed model is obtained using single phase and three transformer. Results obtained from the developed model is validated with the practically obtained outputs. Practical tests executed on transformer show close connectivity with simulated results evidencing the extensiveness of the designed model. en_US
