ABSTRACT:
Method, apparatus and computer-readable code are provided for detecting a location of an incipient ground fault in an electrical propulsion system of a relatively large land-based vehicle, such as a locomotive. The detection is performed essentially in real time and without interrupting operation of the electrical devices that make up the propulsion system (e.g., performed “on the fly”), and consequently there is virtually no degradation in the operational performance of the propulsion system.
