1. An electrical circuit arrangement, comprising:
an inverter and a measuring device designed to identify a short circuit between a conductor and a shielding in a circuit, which is connected or connectable to the inverter, wherein the shielding is connected capacitively to a ground of the inverter, and a pulsed voltage is generated on the conductor by the inverter, wherein the measuring device is designed to evaluate a voltage between the ground of the inverter and the shielding and to generate a short circuit signal when at least one pulse of the voltage occurs.
