Abstract
A system, apparatus, and method () for detecting an electrical short condition in a dynamoelectric machine are described. The method includes determining an operating parameter of a dynamoelectric machine () responsive to at least one output signal of the dynamoelectric machine and providing a transfer function () for predicting a field current of dynamoelectric machine. The method also includes obtaining a value for a predicted field current () of the dynamoelectric machine from the transfer function and the operating parameter and identifying a shorted turn condition of the dynamoelectric machine responsive to a difference between the value of the predicted field current and a value of an actual field current of the dynamoelectric machine ().
