Abstract
A method, system and computer program product for determining the health of a transformer are provided. The method includes computing an effective turns ratio based on a primary electrical parameter associated with a primary winding of the transformer and a secondary electrical parameter associated with a secondary winding of the transformer. The method further includes computing an operational magnetizing current based on the effective turns ratio and primary and secondary currents of the transformer or primary and secondary voltages of the transformer. Finally, the method includes determining an inter-turn winding health indicator based at least in part on the operational magnetizing current.
