The primary purpose of this document is to provide practical information and guidance on the design, operation and maintenance of cathodic protection systems ― galvanic systems in particular ― for transmission and distribution (T&D) structures.
Value to Electric Cooperatives
The objectives of this report are to:
Explain the corrosion processes (underground and atmospheric) in T&D structures,
Highlight the factors that affect the corrosion process in T&D structures,
Describe the fundamentals of corrosion mitigation in T&D structures using a cathodic protection technique,
Explain the required tests and field survey for the corrosion risk assessment of T&D structures,
Provide basic guidelines for the design and maintenance of a cathodic protection system for T&D structures.
