Summary
This paper presents initial results from the deployment of a Distributed Acoustic Sensing (DAS) system using Optical Ground Wires (OPGW) to support Dynamic Line Rating (DLR) applications. Mechanically induced strain measured by DAS is used to extract the perpendicular wind‑speed component, which is subsequently extrapolated from OPGW height to phase‑conductor height.

Despite the inherent complexity introduced by local terrain, vertical wind-profile assumptions, and conductor sag, the extrapolated wind speeds show good agreement with reference measurements from vibration-based DLR sensors installed on the phase conductors.
These results confirm the feasibility of using DAS as a distributed wind-monitoring solution for DLR applications. 1 Introduction The fibers in Optical Ground Wires (OPGW’s) are traditionally used for (internal) communication, but they also offer potential, using it as part of a distributed optical fiber
