Electrical Transmission and Substation Structures 2022
A Structural Engineer’s Perspective on Transformer Installations
Publication: Electrical Transmission and Substation Structures 2022: Innovating for Critical Global Infrastructure
ABSTRACT
Transmission power transformers are the Achilles’ heel of the bulk electric system, since they perform voltage transformations and are located at the beginning and end of the transmission system. Designing a foundation and other associated elements to support a transformer installation is a critical, and sometimes daunting, task. Transmission power transformer installations may require different means and methods than for other substation equipment and structures. This is especially true for large power transformers, which can exceed 750,000-pounds after assembly. Additionally, code revisions and Critical infrastructure protection (CIP) requirements have added a new level of complexity to the design process. In order to achieve a functional, maintainable, and reliable transformer foundation design, it is important for structural engineers to have a working knowledge of the various construction means and methods used for transformer installation, and the supporting components.
