| Objectives | This project aims to 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 disseminated. Test results and demonstrations aim to help us make more informed decisions when deciding whether to implement / deploy such technologies. On successful completion of this work, the following 4 deliverables will be developed successfully: 1) A technical guide reviewing OHTL Inspection and assessment methods: This work focuses on the degradation and inspection of line components, procedures and technologies for inspecting and assessing components. 2) A technical guide detailing methods to assess the condition of overhead electricity transmission: This deliverable details the output of the work conducted to develop an analytical tool to assess overhead line performance in a more protective and risk-based approach. 3) A technical report looking at population assessments of line components: This report will detail techniques and methodologies for the inspection and assessment of a population of all the various overhead line components in-service. 4) A technical report summarising the performance of overhead transmission line component performance: This report will provide a synopsis of findings resulting from periodic analysis of the data associated with the performance of each component. | |
| 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 the area of overhead lines, utilities need to maintain consistent reliability standards, need to understand the condition of our overhead transmission lines and effectively manage and maintain them at their designed level of performance and safety. In order to do this, inspection and assessment is needed to understand the current condition of transmission assets, extend the life of those assets while keeping the aging infrastructure performance at levels that meet the reliability expectations of our consumers. New inspection and maintenance management practices and tools are continuous being developed and they can be efficiently tested, trialled and reviewed through a collaboration with other networks with similar needs. Inspection, Assessment, and Asset Management of Overhead Transmission Lines The project will employ a tiered approach to develop a number of materials and then help to quickly incorporate those tools into everyday work practices. This research project will perform the following tasks: 1. Develop and document an understanding of component degradation, indicators and symptoms of impending failures, as well as effective inspection practices and technologies in the Inspection and Assessment Methods (IAM) Reference Guide, the EPRI Yellow Book. 2. Develop computer-based instruction systems to help in technology transfer of assessments, technologies, and components. 3. Develop and improve field guides for field personnel that help identify and provide information on the condition of components and remedial action if necessary. 4. Develop fleet management approaches to assess the overall health and condition of overhead transmission assets. 5. Develop and host hands-on tech transfer workshops and conferences. 6. Develop techniques for systematically inspecting and assessing an in-service population of various line components to identify the at-risk component classes. 7. Provide a statistical analysis of overhead transmission line component history contained in EPRI’s databases.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
