Experimental and simulation results are presented and discussed. Finally, a promising new method to identify inrush currents, and to distinguish them from internal faults, is suggested.engIncipient winding faultsInrush currentsProtective relayingTransformersPower transformers behavior under the occurrence of inrush currents and turn-to-turn winding insulation faultsconference object2014-05-19http://dx.doi.org/10.1109/ICELMACH.2010.5608303
