CYMCAP/RTTR, Real-Time Temperature Rating

Numerous underground transmission projects are emerging worldwide. Each project requires a substantial investment of time and money in a market where shortfalls and blackouts are not acceptable anymore.

TCCL to provide RTTR system to PEA by Q1-2021. 

Nowadays, it is a universal practice to use Distributed Temperature Sensing (DTS) systems based on fiber optic technology to monitor the cables temperature all over the run. To supplement this technology, CYME introduces its CYMCAP/RTTR Dynamic or Real Time Temperature cable Rating system to extend the monitoring functionality and predict/forecast the behavior of the installation under emergency situations.

CYMCAP/RTTR is designed to provide both steady state and transient thermal analysis. It is based on the IEC Standards 60287 and/or 60853 or finite elements. This function allows the user to be ready, by looking into the future, when an emergency situation arises.

RTTR Operating Modes The Real-time Temperature Rating based on CYMCAP has two modes of operation:

• Estimating the conductor temperature from the fiber measured temperature.

• Performing emergency ratings with the transient engine.
