Objectives The objective of the project is to trial a conductor that can provide high capacity and low noise on the Over Head Line Transmission network. Stringing of the conductor Data Collection for 1 yea rData interpretation and comparison to existing conductor Business Implementation documents
Abstract National Grid use a specific type of conductor on Over Head Line routes in order to increase capacity on existing lines, and avoid building new towers. Due to the conductor construction, it is known to create a nuisance noise that is becoming an issue to people living near the line. National Grid have an opportunity to exploit some research previously conducted in other projects - NIA_NGET0067 and the IFI project "Acoustic Emissions". These two projects found that the ACCR conductor is a high performance conductor (in terms of capacity) and produces a relatively low noise. This project aims to validate the research, but in an operational environment. Demonstration National Grid are building on research conducted in the laboratory at the University of Manchester. In the lab, this conductor demonstrated decreased acoustic emissions in the controlled environment. The project will string a short section (3 spans) of ACCR conductor into both circuits in an existing route, where there are existing noise issues. National Grid will then monitor the conductor in various weather conditions for 12 months, specifically targeting acoustic emissions. This cannot be done on the same route as used in NIA_NGET0067, as one side of the tower uses a CTC conductor, and the other is ACCR. This route would not be suitable for capturing the data regarding acoustic emissions. Produce a direct comparison report between the new conductor, and the existing conductor.
