Abstract
Various embodiments include a system having: at least one computing device configured to monitor a dynamoelectric machine having a rotor including an exciter electrically coupled with a field winding, by performing actions including: obtaining measured data indicating a resistance of the field winding at a plurality of rotor angular positions while the rotor is rotating at a speed below one-hundred revolutions per minute; comparing the measured data indicating the resistance of the field winding at the plurality of rotor angular positions with a threshold resistance range; and indicating a potential fault in the field winding in response to determining the measured data indicating the resistance deviates from the threshold resistance range.
