Cathodic protection – field application

Rectifier

Cathodic Protection (CP) is used to mitigate corrosion on buried or submerged structures.

 

This course covers basic principles and practical application of Cathodic Protection.

 

Students learn and demonstrate proper safety practices, troubleshooting failed components, and field observation.

Lessons include:

 

Basics of corrosion and CP theory:

  • Sacrificial anode CP
  • Impressed current

 

CPCP equipment:

  • Sacrificial anodes
  • Rectifiers
  • Impressed current anodes and ground beds
  • Test stations
  • Reference cells

 

Performing CP measurements:

  • Structure-to-soil potentials
  • Voltage and current measurements
  • Soil resistivity
  • Pipe/cable locating
  • Rectifier readings

 

Continuity tests, and conducting tests to identify shorts CP safety issues
