Timely determination of the temperature profile of the cable transmission line enables the maintenance personnel to operate the line efficiently and optimize the load capacity of the network.
Temperature monitoring system detects overheating and damage of power underground cable with high accuracy of location of breakdown.
Controllers of the OTS product series are distributed temperature sensing (DTS) devices measuring temperature profiles along optical fibers. These controllers belong to the last generation of controllers with high speed and accuracy up to 0.5 m.
The measurement principle is based on Raman scattering. The measurement error is less than 0.5°C.
The technologies used provide a measurement range of more than 16 km from the controller’s immediate location.
The temperature monitoring system is suitable for temperature measurement along the sensor track – fiber optic detector. The sensor detector is installed in the cable screen or fixed on the cable outersheath.
