Course - CP Interference

The Cathodic Protection Interference course focuses on AC, DC, and telluric interference. The course provides in-depth coverage of both concepts and practical application of identifying interference and interference mitigation techniques. Students will learn to identify the causes and effects of interference, conduct tests to determine if an interference condition exists, perform calculations required to predict AC interference.

Classroom instruction is comprised of lecture and discussion, in-class experiments, case studies, and group exercises.
