Aging transmission and distribution systems are at increasing risk of damage due to corrosion and metal loss as they near the end of their design life.  At risk from this corrosion are the costs for repair or replacement, power outages, as well as damage to the electrical grid.  Engineering and maintenance individuals within the transmission and distribution industries should consider attending this course for this critical fundamental information on corrosion of transmission and distribution systems.

Using case studies and project experience, this course will discuss the fundamentals of the science behind corrosion, testing equipment, tower and pole corrosion, distribution systems corrosion, underground transmission corrosion, proper material and coatings selection, cathodic protection, stray current and pipeline induction corrosion, and electric communications corrosion.
