Abstract
This paper presents the results of a research made by IPT – Instituto de Pesquisas Tecnólogicas of São Paulo State and Eletropaulo about the influence of stray currents on the corrosion of electrical transmission tower foundations. The currents were generated mainly by impressed current cathodic protection system and by the electrified traction systems. Mechanisms of capitation and transportation of stray currents through the electric energy transmission net system is discussed.
