Linear Asset Management: a case study of overhead transmission lines

Linear assets are defined as assets whose length plays a critical role in their maintenance Linear asset owners strive to optimize the value and performance of each asset throughout its lifecycle while meeting all of safety, reliability, quality, performance, and regulatory compliance requirements… A case study is used to present the implementation of linear asset management practices for overhead transmission lines (OHTL). More specifically, the purpose of this paper is to propose an Asset Health Index (AHI) for OHTL using a condition-based method and discuss some other monitoring methods (e.g., robot LineVue with non-destructive in-situ inspection technology for conductors and an integral online approach to ensure tower and conductor integrity – OTLM device and strain gauges). In addition, various issues, and challenges for managing linear assets are also discussed.
