Distributed temperature sensing (DTS) system for underground power cables monitoring
Trinius 540/580 systems measure temperature in real time mode along the sensing element with a resolution of 3/6,5 ft (1/2 m). The maximal sensing length is up to 5/10 miles (8/16 km). Sensing element is resistable to electromagnetic interference, chemical effects and the impact of corroding media. Measuring cable does not generate sparks, flame or heat along entire length. Trinius 540/580 system does not require any extra power supply along the entire length.
Trinius 540/580 solutions can be used to measure temperature variations along underground high and medium voltage power lines.
