Abstract

An impressed current cathodic protection system for protecting a structure(1) against corrosion, the system comprising a power supply (8) connected to conversion means (3) for converting the output of the power supply to DC at a required level, the conversion means being connected to the power supply by an electrical connection wherein in use the structure forms a cathode and the conversion means are disposed at a distal region of the electrical connection line and an anode (13) is electrically connected to the conversion means, wherein an electrical connection cable between the conversion means and the anode is of a relatively high current-carrying capacity compared to the electrical connection between the AC power supply and the conversion means, and further comprising an electrical connection cable between the conversion means and the structure, which cable is of a relatively high current-carrying capacity compared to the electrical connection between the power supply and the conversion means.
