This paper presents actual case histories of sacrificial anode cathodic protection installations on a variety of power system pole and tower foundation types. The case histories show strong points and weaknesses of various grounding system and cathodic protection system designs and present some operating system histories. Grounding system design, foundation design and cathodic protection system design recommendations are made for future power line construction projects.
