Abstract
A system and method for locating inter-turn short circuits or ground faults in a rotor winding of an electrical generator. The method analyzes data from a Recurrent Surge Oscillograph (RSO) test, identifies a spike or anomaly in a reflected RSO signal, determines an elapsed time between a transmitted signal and the anomaly in the reflected signal, calculates a distance along the winding conductor to the inter-turn short circuit or ground fault based on the elapsed time, and uses a geometric model of the winding conductor to identify a location of the fault based on the distance. The location of the inter-turn short circuit or ground fault specifies a coil number, a turn number within the coil and a position within the turn.
