Connecting the Grounding Conductor to PE

Direct low-impedance grounding of the AKE is essential for the operational safety of the PLC system. Special
attention should therefore be paid to the mechanical and electrical design of the grounding electrode.
The grounding conductor should be of copper or galvanized steel strip and should be connected directly to the
grounding electrode of the high-voltage system without a branch. Should direct connection to the power
current station ground not be possible in exceptional cases the coupling unit can also be grounded with inclu-
sion of the steel structure of the high-voltage system. In this case the AKE is connected to the steel structure
via a copper conductor of adequate cross section. The connection must be corrosion-proof and have no
contact resistance. The ground connection of the AKE to the steel structure must not be used for other equip-
ment. Steel structures provide an adequate ground for PLC operation only if they are securely connected to
the high-voltage operating ground in their entirety.
