摘要： The invention relates to a system for protecting an electrical device that can be connected to an electrical conductor system, comprising a signal generator for generating a first signal in the conductor system, a detecting device for detecting a second signal, which is based on the first signal, in the conductor system, a determining device for determining physical properties of the conductor system on the basis of the first and the second signal, and a control device for limiting a functionality of the device in case the determined physical properties deviate from predetermined physical properties by more than a predetermined amount.

摘要： The invention relates to an electrical line for connecting two electrical devices, comprising a first segment having a predetermined first length and a first impedance and a second segment having a predetermined second length and a second impedance. The first segment is thereby adjacent to the second segment and the impedances of the adjacent segments are different, so that a change in impedance exists in the region of the adjacent segments.
