Andorra Temperature Measurement Optical Cable Technology

Fiber-optic temperature cables, using Distributed Temperature Sensing (DTS), provide precise, real-time temperature monitoring along power or industrial cables, with immunity to electromagnetic interference and high spatial resolution.

Technology Overview

Temperature-measuring optical cables rely on fiber-optic sensors that detect temperature along the entire length of the cable rather than at discrete points. The most common method is Distributed Temperature Sensing (DTS), which uses the Raman or Rayleigh scattering effect in optical fibers. Laser pulses travel through the fiber, and the backscattered light varies with temperature, allowing continuous, high-resolution temperature profiles along kilometers of cable . These optical fibers are non-conductive, immune to electromagnetic interference, and do not generate self-heating, making them ideal for high-voltage, magnetic, or harsh industrial environments . They can be integrated directly into the sheath of power cables or installed nearby, providing meter-accurate hotspot detection and enabling real-time thermal rating (RTTR) of cable systems .

Applications

• Power grids and underground cables: Monitor conductor temperature, detect hotspots, and optimize load capacity without thermal overload .
• Industrial environments: Measure temperature in high-voltage, microwave, or RF-intensive areas where traditional sensors fail .
• Energy and infrastructure monitoring: Track temperature evolution in pipelines, energy storage, or critical industrial assets .
• Scientific and laboratory use: High-precision temperature measurement in research or environmental monitoring .

Advantages

• Continuous, distributed temperature measurement along the entire cable length.
• High spatial resolution, sometimes sub-millimeter, for precise hotspot detection .
• Electrical insulation and galvanic isolation, ensuring safety in high-voltage applications .
• Passive sensing with no influence on the measured temperature.
• Compatibility with visualization and RTTR software for real-time monitoring and predictive maintenance .
