A leakage sensor determines a signal representative of a neutral-to-ground leakage current or voltage from the neutral point of an electric machine of an associated electrical system. A processor uses the sensed signal to determine incipient faults in at least one component of the electrical system.

Abstract:
One method for predicting incipient failure includes starting an engine of a locomotive; obtaining charge current sample values of the energy storage unit during energy storage unit charging at a predetermined rate for a predetermined period of time; calculating an average value of the charge current sample values; and using the average value of the charge current sample to predict incipient failure in the energy storage unit or the energy storage unit cabling. A related method includes obtaining crank voltage sample values of the energy storage unit during cranking; calculating an average value of the crank voltage sample values; and using the average value of the crank voltage sample to predict incipient failure in the energy storage unit or the energy storage unit cabling.
