Priciple of impreced current protection system
Impreced Current Protection
Cathodic protection after the foreign flow process, the required protection current from the Transformer rectifier is supplied and fed on the foreign power anodes in the object.
The CP System consists of four basic components
- Rectifier for the power supply
- Impressed current anodes
- Anode cable of the rectifier to the anodes, cathode cable of the rectifier to the protection object
- Protection object
Advantage
✔ Protection power output can be easily adjusted or regulated
✔ Low depending on the specific resistance of the soil or water
✔ Long range of the protective effect
✔ Low material removal of anodes
✔ Low effert for measuring the OFF potential
Disadvantage
✔ higher investment costs
✔ Possible interfernce of foreign objects
