Power cable conductor ampacity directly correlates with conductor temperature. Traditional thermocouple measurement fails to ensure real-time monitoring, risking cable operation. Leveraging Raman scattering principles, this study establishes a method for continuous surface temperature detection of long-distance power cables using distributed fiber optics. This approach surpasses OTDR-based measurement in speed and reliability, offering superior online monitoring for cable systems, suitable for widespread adoption.
