Abstract
A method and system for predicting failures in a power resistive grid in a vehicle, e.g., a locomotive, are provided. The method allows for monitoring one or more signals indicative of an estimated grid resistance value. The method farther allows for adjusting the value of the estimated grid resistance relative to a nominal grid resistance value. A comparing step allows for comparing the adjusted value of the grid resistance against the nominal grid resistance value to determine the performance of the respective resistive grid.
