Power cable monitoring - DTS with RTTR / DCR
Today´s power grid operators need to restrict the grids ampacity due to thermal limitations. To protect the infrastructure, high safety margins are applied which limit the efficient use of the power cable infrastructure. Real-time Thermal Monitoring balances the need for asset protection and network performance optimization.
Distributed Temperature Monitoring provides continuous monitoring of high power cable temperatures, detecting hotspots, delivering operational status, condition assessment and power circuit rating data (Real Time Thermal Rating - RTTR, Dynamic Cable Rating - DCR). This helps operators to optimize the transmission and distribution networks and reduce cost of operation and capital. The sensing fiber is either embedded in the power cable, close to the conductors or deployed along the outside of the cable. It is intrinsically immune to electromagnetic interference and provides reliable temperature measurements, ideal for use in a high voltage environment.
