Principle of Fiber Optic Asset Monitoring

Detección distribuida de fibra óptica

Detección distribuida de fibra óptica uses optical phenomena such as raman o dispersión de brillo to measure temperature or strain along the entire fiber. By launching a laser pulse and analyzing the backscattered light, the system obtains a continuous profile of temperature or strain, con resolución espacial tan fina como 1 meter over distances up to 40 kilómetros. This method is essential for monitoring long assets like underground cables and pipelines.

Fluorescence Fiber Point Temperature Sensing

Fluorescence fiber sensors use rare-earth-doped fibers that emit characteristic fluorescent light when excited by a specific wavelength. El vida útil de la fluorescencia or intensity changes with temperature, allowing for muy preciso, interference-free hot spot measurement. These sensors are installed at strategic points such as transformer windings, juntas de cables, and generator stators for direct hot spot detection.

Applications in Power Systems

Transformadores

Fluorescence fiber point sensors are embedded in transformer windings and cores to measure the hottest spots, enabling real-time thermal management and insulation life optimization. This helps prevent failures caused by overheating and supports risk-based maintenance.

Cables de alimentación

Distributed fiber sensors are integrated with underground and submarine cables, providing a continuous temperature profile along the entire route. This enables instant detección de puntos calientes, dynamic cable rating, and precise fault localization, reducing outage time and repair costs.

Switchgear and Busbars

Ambos distributed and point fiber sensors are deployed in switchgear and busbar systems for continuous thermal and partial discharge monitoring. This reduces the risk of arc flash and supports safe, reliable operation in high-voltage environments.

Generadores

Fluorescence fiber sensors monitor stator and rotor winding temperatures, delivering early warning of abnormal heating and insulation issues. This information is crucial for preventing unplanned outages and extending generator life.
