3270: New Below Ground Coatings For Direct Embedded Steel Pole Transmission Line Structures And Assessment Of Existing Coatings And Methods Of Repair

The primary purpose of this document is to review and assess existing coating technologies in various industries in order to highlight their advantages and disadvantages for below-grade applications in transmission and distribution structures. Furthermore, practical information and standard guidelines on coating material selection, surface preparation, coating application, and coating assessment for buried sections of direct-embedded transmission poles are discussed.Transmission and distribution

3247: CPF: Transmission Line Maintenance Benchmarking

Numerous types of inspections at various frequencies are carried out on a transmission line system. This is done for two main reasons: to identify defective components that need immediate attention as well as those that can be corrected over time under a planned program, and to identify issues that require follow-up to determine the full extent of a problem. During inspections, condition data is also collected to support maintenance and capital replacement planning. These inspection activities,

3274: Information Required to Manage the Life Cycle of Transmission Line Assets/Components

With the onset of more formal data-driven asset management practices, utilities have taken steps to enhance their data collection and information requirements. However, in some cases, this has resulted in data collection practices that are not aligned with the evolution of asset management and continuous improvement, resulting in uncertainty as to what is the right, and right amount of, information for the life cycle management of transmission line assets/components. This project is intended to

3237: Spare Part Strategies for Transmission Line Assets

Utilities have realized that proper planning and control of a spare parts inventory is a critical component of an effective asset management program. If the right parts are not on hand when needed (for routine maintenance or emergency repairs), the outage is prolonged and can possibly affect customers. On the other hand, if too many parts are stored, there are excessive costs and overhead.This report reviews the spare part strategies used by some utilities and proposes a framework to determine t

3283: Techniques and Methodologies for Evaluating and Quantifying Risks

This project aims to provide an enhanced understanding of available risk assessment methods and best practices for more accurate assessments, ultimately leading to more effective operations. The review of methods applied across various industries can provide a different perspective, as more mature industries (in employing risk-based methods) may have often suffered similar issues. Asset operators can support decisions involving maintenance strategies, supply chain management, service life extens

3278: CPF: Condition Assessment of Overhead Transmission Line Steel Lattice Towers

The condition of steel members in overhead transmission line (OHTL) towers is critical to the structural integrity of the system. Rust can develop in local areas and spread across the member, compromising its strength and establishing weak points. Failure of members due to rust damage is a serious risk and can lead to the structure failing, causing power outages and significant knock-on costs.The objective of this report is to provide the methods and rationale that were used to inspect and asses

3267: CPF: Inspection Methods (Visual) for Transmission Line Assets/Components with an Emphasis of Collecting Complete and Accurate Data

CEATI International’s Transmission Line Asset Management Interest Group (TLAM) seeks to build on past efforts by assisting its member utilities in establishing “best practices” for inspection and maintenance programs for their transmission line assets.The objective of the project is to provide methods and inspection practices for transmission lines in order to improve the quality and completeness of the data collected from various patrols, as well as to increase the consistency

3255: CPF: Commissioning Guide for Transmission Lines

The main purpose of this report is to develop for the CEATI members a commission guideline documenting detailed step by step directions on how to develop a plan to commission newly installed power transmission lines. The commissioning guideline identifies the deliverables and tasks owned by the commissioning agent during each construction phase, their roles and responsibilities and the overall commissioning process to ensure that the owner’s project requirements are met. In addition, the r

3290: Application of Artificial Intelligence in Overhead Transmission Lines Maintenance

Power systems are complex and have a significant impact on modern life. Modernization, economic growth, and social progress are influenced by power system technology. Advanced protection and control techniques are required to operate these complex systems in a safe and reliable manner. Transmission lines are the backbones of power systems, and they are generally designed to avoid the impacts of a variety of unpredictable events. However, power systems are facing the effects of unexpected conditi

3282: Transmission Line Failure Investigations – Guidelines for Collecting Incident Data and Evidence

When failures of overhead transmission lines (OHTL) occur, the opportunity to collect information and materials that would be invaluable for assessing the causes and improving engineering, construction, and asset management processes is often lost as crews seek to restore and reenergize failed facilities. This loss is in part due to a lack of consensus understanding among utility personnel – including first responders – regarding the value of collecting failure event information befo
