Cathodic Protection Interference (CPI) (Conforming with NACE Standards)

This comprehensive Cathodic Protection Interference (CPI) course focuses on AC and DC interference.

About this Course

This comprehensive Cathodic Protection Interference (CPI) course focuses on AC and DC interference. It provides in-depth coverage of both theoretical concepts and practical applications of identifying interference and interference mitigations techniques. The candidates will learn to identify the causes and effects of interference, conduct tests to determine if an interference condition exits, and perform calculations required to predict AC interference. It, also, covers CP technology, basic electricity, electrochemistry and corrosion concepts, CP theory, CP systems, and CP field measurement techniques. It provides knowledge for testing on both galvanic and impressed current CP systems. It covers AC and DC stray current interference, and advanced field measurement techniques. It provides knowledge and techniques for testing and evaluating data to determine the effectiveness of both galvanic and impressed current CP systems and to gather design data.

Course objective
