Corrosion protection for vertical metal mast anchored in ground involves connecting protective anode directly to mast as sacrificial anode or to DC source as inert anode

摘要

The method involves connecting the mast (1) cathodically and surrounding it in the ground (2) at a distance with a closed and at least approximately annular protective anode (4) that is connected directly to the mast as a sacrificial anode in the case of cathodic protection or to the positive pole of a DC source as an inert anode in the case of electrolytic cathodic protection, the mast being connected to the other pole of the source.
