Practical Considerations for Design and Assessment of Corrosion in Electric Substations and Transmission Lines - Standards and Methodological Perspectives

This article delves into the issue of corrosion in power transmission lines and electrical substations. Corrosion, being a natural phenomenon, can have detrimental effects on the metallic structures utilized in substations and transmission lines, ultimately impacting their performance and service life. The article focuses on two key aspects: standard considerations and methodological approaches related to corrosion in transmission lines and substations. In terms of standard considerations, the article examines the existing standards and regulations governing the inspection and control of corrosion in electrical substations and transmission lines. This encompasses specific standards for material selection, protective coatings, periodic inspections, and preventive maintenance. Regarding methodological approaches, the article explores various techniques and methodologies employed for evaluating and mitigating corrosion in transmission lines. It discusses inspection and monitoring methods, as well as strategies for corrosion protection such as the application of protective coatings and the implementation of cathodic protection systems. By addressing both standard and methodological aspects, this article provides insights into combating corrosion in power transmission infrastructure, aiming to enhance the longevity and reliability of electrical substations and transmission lines..
