This course provides a focused understanding of mechanical and civil engineering principles for overhead AC transmission lines. It covers tower design, conductor behaviour, sag–tension analysis, vibration control, stringing methods, and testing in HV/EHV systems. Civil topics include soil investigation, foundation types, erection practices, safety measures, and modern analysis tools. Emphasis is on industry practices used in utility and EPC projects, supported by numerical analysis, MATLAB-based sag studies, and real-life case examples.

Objectives: Learners will understand design principles of transmission towers, analyze mechanical loads, perform sag and tension calculations, assess environmental impacts, evaluate vibration and damping, and apply foundation design and safety practices in field conditions. Target Learners / Audience: Suitable for electrical and civil engineering students, graduate trainees, transmission line professionals, utility personnel, and engineers seeking practical expertise in transmission line design, construction, and maintenance.

Let’s begin this module by understanding the fundamental principles involved in the mechanical design of overhead AC transmission lines, including tower classification, loading conditions, sag and tension analysis, and conductor clearances. The module discusses the influence of terrain, ecological, and seismic conditions on transmission line design. It also introduces sag template preparation, tower spotting concepts, and the application of MATLAB simulation techniques for analyzing sag under wind and ice loading conditions used in modern transmission line engineering projects.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
