520 ## - SUMMARY, ETC.
Summary, etc. Reduction and methods of control of switching transients have become important concerns to the power industry. Power transformers are vital components in electric power system. This thesis presents a technique for attenuation of transformer inrush current. The proposed technique is applied to 66/11.5 kV, 25 MVA power transformer with delta connected winding using ATP-EMTP software. The main idea of the proposed technique is using controlled transformer energization preceded by controlled de-energization to achieve a defined and repeatable residual flux with its lowest possible level for individual phases, and then determine the optimal instant of energization considering the core residual flux
