Distributed Sensing on a 110-kV Overhead-Line Maintenance Operation on an Operational Optical Ground Wire

We demonstrate dual-modal distributed sensing on an operational 110-kV OPGW during crane maintenance. DAS resolves meter-scale lifting events and matches impulsive events to phone audio, while DTSS quantifies post-reclamping residual strain up to $\sim$398 $με$, enabling maintenance verification and asset monitoring in transmission grids. --- Source: arXiv:2609.18767v1 - http://arxiv.org/abs/2609.18767v1 PDF: https://arxiv.org/pdf/2609.18767v1 Original Link: http://arxiv.org/abs/2609.18767v1...
