IMPRESSED CURRENT CATHODIC PROTECTION |
摘要 |
An impressed current cathodic protection arrangement includes an elongate metallic structure to be protected and cathodic protection apparatus which comprises a DC power supply and an anode. One terminal of the power supply is connected to the structure at a connection point and another terminal of the power supply is connected to the anode. The arrangement includes monitoring apparatus for monitoring effectiveness of cathodic protection provided by the cathodic protection apparatus by determining the electrical potential of the structure relative to surroundings at at least one location which is spaced from the connection point.
