The proposed method is able to detect winding insulation failures and to distinguish them from magnetizing inrush current transients. Experimental and simulation results are presented and discussed.engDifferential protectionIncipient winding faultsInrush currentsPark's vectorp–q power theoryTransformersjournal article2014-05-16http://dx.doi.org/10.1016/j.epsr.2011.11.004
