摘要： 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.

摘要： A resistive grid enclosure for a vehicle having a dynamic braking capability, the grid enclosure defining an air inlet, an air outlet, and an airflow path through the enclosure from the air inlet to the air outlet. A resistive grid disposed within the enclosure is cooled by air flowing through the airflow path from the air inlet to the air outlet. The airflow path is configured so that an inlet airflow is heated by absorbing heat from the resistive grid and directed toward the air outlet forming a heated outlet airflow. The airflow path is further configured to direct at least a portion of the heated outlet airflow into the air inlet to reduce blockage of the air inlet by ice or snow.
