For drowning the no-load closing process,the transformer produces a magnetizing inrush current which will dam-age the transformer relay,transformer equipment and power quality.To restrain the damage,the transformer inrush cur-rent is analyzed,and the methods of identification and inhibition of transformer inrush current are summarized.The popular method is phase selection control.The key technologies of phase selection control,such as the action and error compensation of the operating mechanism,are expounded.
