In order to monitor an electrical supply system, in particular of a motor vehicle, which is at least partially mounted on a carbon-fiber supporting structure, a monitoring unit is provided and electrically connected to the carbon-fiber supporting structure at preferably a plurality of measurement points. Voltage values are tapped off at the measurement points and compared with permissible voltage values. If the voltage values exceed permissible maximum limits, on account of a short circuit for example, this is judged to be an indication of an impermissible current across the carbon-fiber supporting structure, and a power source is disconnected from the supply system, in particular.
