<p>Arrangement for cathodic protection from corrosion of a metal body (1) surrounded by an electrolytic medium (4), comprising a metal anode body (3) which is to be introduced into the medium (4) and has a lower electric quiescent potential in the medium (4) than the body (1) to be protected, where, by means of a circuit comprising at least a Schottky diode (7) operating above a certain threshold voltage, the body (1) to be protected and the anode body (3) are electrically interconnected such that there is provided a difference in potential between the anode body (3) and the body (1) to be protected which is at least equal to the threshold voltage, but smaller than the quiescent-potential difference of the body (1) to be protected and the anode body (3). <IMAGE></p> |
