| 摘要 |
The invention relates to a device and to a method for monitoring an electrical network (1) in a rail vehicle, wherein the electrical network (1) comprises at least one converter (C), at least one drive motor, at least one first phase line (P, P1) for electrical connection of the at least one converter (C) and the at least one drive motor, wherein a magnitude of a current change of a first phase current (I, I1) is determined, wherein a network error in a partial network (TN_M) on the machine side is detected if at least one criterion based on the current change is met, wherein the criterion based on the current change is met when the magnitude of the current change of the first phase current (I, I1) is greater than a predetermined current change threshold value (SW1). |
