Abstract: Due to the impact of inrush current of transformer, made a voltage drop by source impedance as well as by sensitive loads. That’s why, necessary action is required to reduce the inrush current. Many factors like, secondary winding load, material of transformer core, Saturation flux/residual flux of transformer core, capacity of transformer, supply impedance, voltage-starting phase angle, are affecting the inrush current of transformer. Some different types of methods for inrush current reduction are listed in this paper. Out of that, sequential switching method is adopted for the reduction inrush current.
