DTS applied to power cables
The probe cable is laid on the high-voltage cable to be tested, and the temperature distribution and temperature change trend of the high-voltage cable covered by the probe cable can be monitored in real time.
Set the alarm temperature, alarm temperature, heating rate and temperature difference alarm in sections.
The distributed optical fiber monitoring and alarm system is temperature monitoring, alarming, analysis, management, and taking preventive measures for power devices such as high-voltage cables.
The distributed optical fiber temperature sensing system consists of optical fiber temperature measuring host, temperature sensing fiber, system management software and related accessories. It uses Raman scattering and OTDR technology to realize temperature monitoring and positioning. Distributed optical fiber temperature sensing products use OTDR technology for temperature monitoring and positioning. It is a real-time, online, continuous temperature measurement system. The system can accurately detect the temperature of the temperature measurement point, and has the advantages of real-time online, high temperature measurement accuracy, intrinsic safety and immunity to electromagnetic interference. It can be widely used in electric power, petrochemical, transportation, metallurgical and other industrial places, in the production process. Real-time online monitoring of temperature conditions eliminates faults and accidents in the bud, and truly prevents them from happening.
