Abstract: Nature of magnetizing inrush current is non-symmetrical. The magnitude of magnetizing inrush current is five to ten times the rated magnetizing current and sometimes it is more than full load current of transformer due to addition of transient component. Control and reduction of inrush currents of energizing transformers and reactors is an important problem in electric power systems where different methods are utilized for this purpose. This paper compares two different methods to minimize the inrush current through the simulation result done with MATLAB simulink.
Keywords: Switching Transient, Inrush Current, Point-on-Wave.

Scope of the Article: Routing, Switching and Addressing Techniques
