Magnetizing inrush current in transformers results from any abrupt changes of the magnetizing voltage. This may be caused by energizing an unloaded transformer, occurrence of an external fault, voltage recovery after clearing an external fault and out-of phase synchronizing of connected generator. Therefore, a detailed analysis of the magnetizing inrush current under various conditions is necessary to evaluate voltage dip, and protective relay operation.
