摘要： A running gear for an electric rolling stock has coupling devices for coupling the output shafts of traction motors to the input shafts of reduction devices which are provided with electrically resistive elements so as to prevent return current from flowing therethrough. Therefore, the coupling devices possess a higher level of resistance than the grounding resistance of the grounding devices, thereby enabling any return current to be prevented from flowing through the coupling devices. Thus, the running device can be kept free from electrolytic corrosion.

摘要： A method and an apparatus for providing protection to a generator are disclosed. A reference is determined out of rated capability of the generator. Based on the reference, and field current and output conditions of the generator, there is determined a drop in generator performance due to a temperature condition of the generator. Accounting for the drop in generator performance, operation of the generator may be modified to a generator output limit mode.
