Summary:A method for analyzing electrical shorts in field windings of a synchronous machine having a rotor using a magnetic flux probe, the method includes: monitoring flux signals generated by the flux probe wherein the flux signals are indicative of magnetic flux emanating from the field windings; electronically storing flux data obtained from the monitored flux signals and indicative of electrical shorts in the field windings; automatically analyzing the stored flux data to identify field windings having the shorts and to count the shorts in each identified field winding, and automatically displaying information identifying the field windings with shorts and a number of shorts in each field winding.
