Question: What Is an Acceptable Target Reliability for High-Voltage Transmission Lines?
Publication: Electrical Transmission and Substation Structures 2018: Dedicated to Strengthening our Critical Infrastructure
ABSTRACT
With the national interest in critical lifeline infrastructure system performance and resiliency it may be time for the high-voltage transmission line industry to consider the current reliability level of an electric transmission line system. ASCE 7-10 and 7-16 standards have introduced target reliabilities for buildings and other structures. The question maybe asked, in the near future, what is the current design reliability level of a high-voltage electric transmission line and how does it compare with ASCE 7 target reliabilities? Probability/reliability based design (P/RBD) of transmission lines is not new to transmission line designers. In the 1980s, and into the 1990s, probability based design was being investigated for application to transmission lines. A significant number of studies were completed to better understand the reliability provided by transmission line structural design practice. Also, there is data collected on transmission line failures, and full-scale tower test results that can be used to consider the question of current reliability levels. Based on available information, are existing levels of design reliability acceptable and if not where should the industry target transmission lines for performance base design concepts? This paper will introduce the question, what is the acceptable target reliability for a transmission line, to current and next generation of transmission line engineers.
