Abstract: In power transformer, initially current is very high value, which causes to produce the inrush and it affects the transformer core during the period of initial current and this initial current is known as magnetic inrush current. During this period the life of transformer, protective equipment, as well as power quality is of supplying power will be reduced. So, this initial current reduction is very important for the reduction of inrush, controlled transformer switching can be provided to reduce the magnetic inrush current. This paper shows the practical consideration of minimization of magnetic inrush current as well as the experimental result of the simulation. In this paper use a thyristor to control the firing angle of current. This paper shows the theory to explain an experimental result of the reduction of inrush current at different firing angle using MATLAB simulation
