    摘要: A method and system is provided for detecting and performing diagnostics regarding an incipient ground fault that may occur in an electrical propulsion system of a traction vehicle, such as a locomotive, transit vehicle, or off-highway vehicle. The method allows providing a first ground connection for the electrical propulsion system. This first ground connection forms a grounding path generally used by the electrical propulsion system during normal operation. The method further allows providing a second ground connection for the electrical propulsion system. This second ground connection forms a grounding path selectively usable in lieu of the first ground connection. A control strategy is defined for switching between the first ground connection and the second ground connection. A respective leakage current associated with at least one of the first and second ground connections may be monitored. Switching between the first and second ground connections may be controlled based on the monitored leakage current associated with at least one of the first and second ground connections.

    摘要: A compressed air system and method of operating the system wherein the slip between the compressor motor and its powering alternator is used as an indication of whether the compressor is running in a loaded or unloaded mode. A slip parameter such as % Slip is determined and compared to an allowable value in real time. If the compressor is determined to be erroneously in a loaded mode, a corrective action may be taken to reduce the probability that the motor is later started with the compressor still in the loaded mode.
