Abstract
Method for detecting a protective conductor failure inside a cable including a plurality of conductors, in which at least one conductor has a shield and this shield is respectively connected to a potential at a first end and at a second end of the cable, wherein, in order to drive its potential to a predefined potential value, the shield is actively electrically supplied at at least one end of the cable. In this case, the cable may be a charging cable which is connected, by the first end, to a charging pole and is connected, by the second end, to a battery configured to be installed in an electric vehicle, and the shield is actively supplied at the first end of the cable which is connected to the charging pole.
