CP 2-Cathodic Protection Technician
6-Day Classroom Course
Description
The CP 2-Cathodic Protection Technician Course is an intensive 6-day course that presents CP technology to prepare students for the Cathodic Protection Technician Certification Examination. Course topics include intermediate-level discussions of corrosion theory and CP concepts, types of CP systems, AC and DC stray current interference, and advanced field measurement techniques. This course provides 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. The course involves lectures and hands-on training with equipment and instruments used in CP testing. Hands-on training at outdoor facilities is also included, weather permitting.
Who Should Attend
This course is designed for persons who have a working knowledge of CP, or who have extensive years of CP field experience with a technical background. Students must complete a preliminary application for certification at least 60 days in advance so that education and prerequisites can be verified. In-depth high school chemistry and mathematics courses including algebra, balancing equations, conversions of units, logarithms, and graphs; the NACE Basic Corrosion course, CP 1-Cathodic Protection Tester or equivalent; and comprehensive knowledge of electrochemistry, electricity, electrical laws and series and parallel circuits, meter operation, and CP fundamentals are necessary for understanding the material in this course
