Konstantinos Alexoudis presents dual-modal distributed sensing for power line maintenance at ECOC 2026
Poster session will examine how acoustic and strain sensing can verify high-voltage line maintenance and improve transmission grid monitoring
- Speakers: Konstantinos Alexoudis, research engineer for infrastructure monitoring at Adtran
- Topics: Distributed sensing on a 110kV overhead-line maintenance operation on an operational optical ground wire
- When: Wednesday, September 23, 3:30 p.m. CEST
- Where: ECOC 2026, The Malaga Trade Fair and Conference Center (FYCMA), Málaga, Spain https://ecoc2026.org/ecoc2026
High-voltage transmission networks rely on optical ground wire (OPGW) for communications and operational support. Maintenance activities can place mechanical stress on this infrastructure, creating a need for accurate monitoring and verification. Distributed sensing technologies offer new ways to observe maintenance operations and assess infrastructure condition using existing fiber assets.
In this poster presentation, Konstantinos Alexoudis will discuss results from dual-modal distributed sensing deployed on an operational OPGW during a maintenance operation on a 110-kV overhead line. He’ll demonstrate how distributed acoustic sensing detects and characterizes maintenance activities, while distributed temperature and strain sensing reveals a localized residual strain signature following reclamping. Attendees will learn how these techniques can support maintenance verification and ongoing asset monitoring using existing network infrastructure.
