In high‐voltage distribution systems, there are many power quality troubles due to voltage dips. Otherwise, magnetizing inrush currents cause voltage dips. To suppress voltage dips, it is necessary to identify magnetizing inrush current phenomena. In this paper, the authors propose a new identification method. The principles are that the saturation start and end flux are equal and the inrush current pattern exists. To avoid interference with saturation area overlap, the rectangular coordinate method is adopted. © 2012 Wiley Periodicals, Inc.
