CP 2 - Cathodic Protection Technician

Cathodic Protection 2

Cathodic Protection 2 - Technician (CP2)

The CP 2 – Cathodic Protection Technician course provides intermediate-level training in both theoretical knowledge and practical techniques for testing and evaluating data to determine the effectiveness of both galvanic and impressed current CP systems and to gather design data.

Classroom instruction is comprised of lectures and hands-on training, including using equipment and instruments for CP testing.

Who should attend

This program is intended for personnel involved in testing the effectiveness of CP systems, troubleshooting and/or recording this data, including:

  • CP field personnel
  • CP Testers or
  • Personnel supervising CP Testers

Learning objectives

  • Test and troubleshoot rectifier component parts
  • Perform simulated CP related field tests (including interrupted structure-to-electrolyte potentials, current requirement, continuity, shorted road/railroad casing and, layer soil resistivity tests) and evaluate the results
  • Perform tests to verify the presence of stray current interference (primarily related to underground pipelines) and recommend method(s) to mitigate the interference
  • Conduct and interpret different current measurements
  • Interpret voltage (IR) free readings, polarization formation and decay tests
  • Maintain records, including data plotting and analysis
  • Summarize induced AC voltage on pipelines and the methods of mitigation
  • Purpose and uses of corrosion coupon test stations
  • Depending on the jurisdiction review code CP criteria requirements related to CP



A knowledge of the following is required for understanding the material in this course:

  • Algebra and geometry
  • Electrochemistry: theory including electrochemical and galvanic series;
  • Corrosion theory including polarization under different conditions;
  • Electricity: basic electrical laws, series and parallel circuits;
  • Cathodic protection: fundamentals, criteria, sacrificial and impressed current equipment including troubleshooting;
  • Stray current interference, primarily related to underground pipelines.
  • Testing: including voltmeters, ammeters, shunts (and calculations), ohmmeters, reference electrodes (and conversions), isolation and soil resistivity.
