Abstract

Transformer is a vital and major component in any electrical power system. When transformer is energized high peaky current is observed. This current called inrush current. This current has undesirable effect on transformer including reduction of the life time of transformer, Protective relay miss-operation and melting of fuse elements. In this paper different techniques for the mitigation and reduction of the transformer inrush current are investigated. It is found that, the sequential phase energization is the most effective one.
