NIA SSEPD 0020: Overhead Line Monitoring System (CNI Guard)

Key activities

This project develops a previous IFI distribution overhead line monitor; that in-situ can differentiate between natural everyday overhead line movement and unusual/significant disturbances, which if occurs triggers a notification. The concept has been developed with a suitable onward communication medium, which is self-powering, has a low energy signal requirement and can be attached to a wooden pole.

Expected outcomes

This project will be successful if the trigged notifications and the onward communication system are proved to be robust and reliable. In addition the overhead line vibration monitoring system needs to be able to demonstrate that its output can be incorporated into the Control Room to aid visibility of the network.
