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
- 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.
Applicants not having the below knowledge and training are encouraged to attend the applicable course(s) before registering for this course.
