Abstract
A method detects an arc fault in an electrical circuitry. The electrical circuitry includes a controller, an energy storage and a plurality of loads each connected to the energy storage via a respective load path. A current measuring device determines current measurement values describing an energy storage current is assigned to the energy storage. Voltage measuring devices for determining voltage measurement values describing a load voltage at the respective load are assigned to said loads. The current measurement values and voltage measurement values are continuously transmitted to the controller via at least one communication link.
