Utilities manage the safety and reliability risks of overhead lines through inspection programs designed to detect conditions that warrant mitigation, with an objective to pre-empt or postpone the occurrence of some types of failures. Inspection programs consider age, condition, operating environment, feasibility of performing routine maintenance, regulatory requirements, and other factors in setting the frequency and scope of routine and special patrols. This project provides resources that highlight the interrelationships among transmission line inspection methods, likelihood, consequences, and risks of various types of failures, defects, and conditions that may present indicators of pending failures, as well as the detectability of obvious and latent defects and conditions.
