Overview & Events

Reliability of an underground transmission system depends on highly skilled utility engineers working throughout the life cycle of design, construction, installation, operation, and maintenance of the system. It is essential to retain cable system institutional knowledge and support the next generation of technical leaders. The project addresses the following needs with knowledge, methods, and tools:

• Knowledge management of EPRI research and development project results and industry experiences.
• Investigation results of advanced tools and techniques for effective cable system management.
• Knowledge transfer on the various topics covering design, construction, installation, operation, or maintenance of both extruded and laminar dielectric cable systems.

This project intends to provide resources and technical support to current and future cable engineers. Participants may be better equipped with captured knowledge, transferred technologies, and educational materials, resulting in more reliable and cost-effective transmission cable systems. Utility engineers can apply the results of this project by participating in educational sessions while interacting with industry subject matter experts and other experienced utility engineers. For example:

• The educational workshops and workshop proceedings can be used to equip utility engineers and improve work productivity for long-term system performance.
• The updated Underground Transmission Systems Reference Book and Increased Power Flow Guidebook can be used to validate system designs, improve system operation and maintenance, and increase or optimize ratings of transmission cable lines.
• The framework for the comparison of overhead and underground power transmission can help to better understand the factors to be considered in planning for a new transmission line.

Approach

This project focuses on knowledge management in underground transmission. It provides updates of the EPRI Underground Transmission Systems Reference Book and Increased Power Flow Guidebook. It provides semiannual educational sessions and reports investigation results on various topics related to design, installation, operation, and maintenance of underground transmission systems.
