The amount of inrush-current relate to ampere-turn of each side of transformer winding which are equal approximately. Physical characteristics of wound coil such as Far or Close to core (coil diameter) or length of energizing coil influence on coil inductance (X) that formed to inrush current amount and its variations; therefore we must zone on actual equivalent of coil reactance and resistance in transformer energizing conditions for control of inrush currents. Of course, the existing of linked tertiary winding to both of primary or secondary winding (with regard to relevant resistance) can be help to faster decaying of inrush currents.
