Highly efficient smart system for inspecting grounding mechanisms at transmission towers
Measuring electrical systems and particularly grounding systems is a notoriously dynamic and complicated process, making it hard to conduct analysis and diagnostic work. This enormous complexity requires innovative new models to provide added flexibility and evolvability.
The TABÓN project offers a brand new technology for verifying, inspecting and predicting power line performance, specifically in relation to grounding systems, so as to improve the process of measuring ground resistance while enhancing management efficiency.
To accomplish this wider goal, the following specific objectives have been successfully completed in relation to the main activities envisaged under the project:
Tool for determining the age of medium-voltage cable in underground power distribution lines
The overriding objective of the MATUSALEN project is to develop an advanced interoperable technological solution featuring cutting-edge hardware and an innovative expert system for estimating the wear of medium-voltage cables found in underground power grids, thus improving the way the assets are managed and allowing for an optimum roll-out of future smart grids.
The project focuses on the ageing and wear of both cables and instrumentation (sensors used to run system self-diagnostics and provide historical data) within the smart grid and will ultimately offer an innovative one-stop solution for managing medium-voltage electrical assets. The technology can easily be exported and adapted to international power grids.
The project envisions the following specific objectives:
The project is expected to be completed in 2017 and is currently under development through the following activities:
Development of materials for power line insulators and electrical switchgear capable of operating in extreme conditions and to ensure a long useful life in medium-voltage systems
The general objective of the project is to obtain new insulators for high-voltage lines and switchgear with improved properties, making them fit for extreme operating conditions and environments in which components age and degrade more rapidly. This will also help improve quality of supply and the efficiency of power distribution networks by reducing the number of outages affecting polymer line insulators.
To accomplish this goal, the following activities are under way:
The project is expected to be completed in 2017 and will lead to substantial improvements in the quality of the components installed across the grid. Measurable short-term benefits include improved materials that will outperform traditional silicons under trial conditions, while the mid-term benefits will include a reduction in line insulator outages as part of the strategy of continuously improving quality of service.
