Discussion on Transmission and Distribution (T&D) structures and system-wide cathodic protection as a mitigation technique. In general soil, corrosivity, lack of cathodic protection/coating, stray current AC interference and copper grounding should be considered in design of T&D structures.
Transmission and Distribution (T&D) structures are among the most often used and safest forms of transmission of electricity in the United States however those tasked with maintaining these aging structures require an in-depth understanding of corrosive environments (soil and atmosphere) and cathodic protection for galvanized structures. Coating and cathodic protection can be applied to mitigate corrosion. Structures protected from accelerated corrosion in this application include: · Galvanized Steel T&D Structures · Weathering Steel T&D Structures · Galvanized Anchor Rods. In general soil, corrosivity, lack of cathodic protection/coating, stray current AC interference and copper grounding should be considered in design of T&D structures. These factors are of primary consideration when accelerated corrosion attack occurs. If identified early on potential failures can often be prevented. This presentation will include discussion on T&D specific structural zones and system-wide cathodic protection as a mitigation technique. Factors that are associated with these forms of failure and cathodic protection will be considered as will the general cathodic protection design concepts that should be applied to limit corrosion in these galvanized and weathering steel structures.

Repeated cyclic potentiodynamic polarization (CPP) measurements were performed in different environments for both carbon steel and Type 304L stainless steel. The effect of different environmental species, nitrite and hydroxide on repassivation/reactivation mechanism of carbon steel is examined.
