Design of Electrical Transmission Lines ─ Structures and Foundations

This book will cover every structural system used in high-voltage transmission lines and their associated foundations, hardware used to support conductors, fabrication and assembly and more. In most developing countries, the term “transmission structures” usually means lattice towers. That term actually includes a vast range of structural systems and configurations of various materials such as wood, steel and concrete. This work aims to discuss those structures and fill existing knowledge gaps, forming a companion volume to the volume on Line and System Modeling.
The book is aimed at students, practicing engineers, researchers and academics. It will contain beneficial information to those involved in the design and maintenance of transmission line structures and foundations. For those in academia, it will be an adequate text-book / design guide for graduate-level courses centering on the topic. Engineers and managers at utilities and electrical corporations should find the book a useful reference work.

Dr. Sriram Kalaga is currently a Senior Engineer in the Transmission Line Division of Ulteig Engineers. He holds bachelors, masters and doctoral degrees in Civil engineering with a specialization in Structural Engineering and Mechanics. He has published more than 35 research papers in various journals and conferences. His research background included finite element methods, buckling of beam-columns, nonlinearities, low-cost composites and reliability-based approaches.

He has been involved in transmission line design in the USA for 16 years while his overall experience as a Civil Engineer spans over 36 years. As a consulting engineer, he developed various in-house design manuals and technical specifications related to transmission structures.

He conducts regular seminars on transmission line design and also participates in teaching workshops on transmission structural design. He is currently a guest editor for an International Civil Engineering Journal and has advised graduate students on their theses. In addition to being a member of ASCE, AISC and ACI, he is currently serving on the ASCE-FRP Blue Ribbon Committee on composite transmission structures. He is a licensed professional engineer in several states in the USA.?

Dr. Prasad Yenumula is currently a Principal Engineer from the Transmission Line Engineering System Standards of Duke Energy.? He earned his bachelor’s, master’s and doctoral degrees in Civil engineering along with an MBA degree with a specialization in Global Management. With a post-doctoral fellowship in engineering, he published more than 50 research papers in various journals and conferences. He worked as a line design engineer, line standards engineer and lines asset manager in the US & Canada for over 20 years. He was responsible for managing and leading a number of line projects and special assignments, along with developing various technical standards & specifications.

He is also a professor (adjunct) with Gonzaga University, Washington and contributes to the development and teaching of the on-line transmission & distribution engineering Master’s program. He also teaches business students at the University of Phoenix. He offered training classes in the areas of line design, standards and line design software.? He was invited to make several presentations, was a reviewer of research papers, an advisor to master’s students and an examiner for doctoral students.

He is currently the Chair of line design task force of the Electric Power Research Institute (EPRI) and Vice-Chair of CEATI (Center for Energy Advancement through Technological Innovation) International’s TODEM interest group. He is a member (alt) of NESC (National Electrical Safety Code) Subcommittee-5 (Strength and Loadings), EEI’s (Electric Edison Institute) NESC/Electric Utilities Representative Coordinating Task Force and ASCE (American Society of Civil Engineers), ISSMGE, SEI and DFI. He is Duke’s industry advisor to NATF, NEETRAC, EPRI and CEATI.? He is also in various other national standard committees such as ASCE 10 on lattice towers, ANSI C29 on insulators and on the ASCE-FRP Blue Ribbon Panel review team. He received twelve awards for his engineering, research and teaching efforts which include best Ph.D. thesis, best papers and four faculty of the year awards.
