The invention relates to a device and a method for monitoring an electric network in a rail vehicle. The electric network includes at least one power converter, at least one permanent magnet machine, and at least one first phase line for the electrical connection of the at least one power converter and the at least one permanent magnet machine. The first phase line is interrupted. A potential difference is determined between a machine-side part of the first phase line and a reference potential and a potential-difference-dependent variable, wherein a speed of the permanent magnet machine and, as a function of the speed, a speed-dependent reference variable are determined. A deviation of the potential-difference-dependent variable from the speed-dependent reference variable is determined, wherein a network fault is detected if the deviation is greater than a predetermined threshold value.
