Abstract The electricity industry faces challenges that National Grid recognises are more cost-effectively and efficiently dealt with through international collaboration initiatives. In particular, challenges whose solutions require statistically diverse data sets and/or significant trialling and testing in different environments, under various conditions and/or diverse ways. The Electric Power Research Institute (EPRI), with its wide international membership, is one of the routes through which these initiatives can be delivered and stakeholder value maximised. This approach of managing collaborative projects is beneficial to National Grid and our customers, providing valuable information, learning and knowledge, which would be more expensive to formulate on an individual basis. In 2015, a benchmarking exercise by National Grid has determined the largest leverage within Overheads Transmission for the UK consumer is achieved through involvement in the following five projects: Inspection, assessment and asset management of overhead transmission lines Structure and sub-grade corrosion management Live working: research, techniques and procedures Performance and maintenance of high-temperature conductors New and emerging inspection and sensing technologies Inspection, assessment and asset management of overhead transmission lines This project is developing a mix of tools, technology transfer methods and events, and information that will help members improve their line inspection and assessment as well as asset management approaches. Structure and Sub-Grade Corrosion Management This project provides information and tools to better understand how the environment influences subgrade corrosion types, identifies methods to locate possible damages, and methods to remediate and mitigate the corrosion damage. Live Working: Research, Techniques and Procedures This project develops tools, procedures and training materials for live and de-energised work at HVAC lines to enhance worker and public safety, work efficiency, and reduction in cost and duration of maintenance outages. Performance and Maintenance of High-Temperature Conductors This project conducts research to address some of the outstanding issues related to high-temperature conductors such as how to quantify a carbon-fibre core conductor. The project develops a guide to assist utilities in the proper selection and application of advanced conductors. Maintenance tools and procedures for this new type of conductor will also be identified and established, including the development of a cleaning solution for various advanced conductor systems. New and Emerging Inspection and Sensing Technologies This project will document the latest inspection and sensing technologies for overhead transmission lines, as well as early adopters’ experiences with these technologies. Some technologies are tested and evaluated and results made available. Test results and demonstrations help members make more informed decisions when deciding whether to apply or deploy such technologies.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
