Real Time Thermal Rating (RTTR) systems and distributed temperature sensing (DTS) technologies have been used within power cable condition monitoring to rate cables since the 1990’s.  The benefits of incorporating DTS and RTTR into power transmission operations were recognised following a well documented power cable failure in Auckland in 1998 which shut down the city’s central business district.

What are the principles and benefits of a Real Time Thermal Rating systems?

Real Time Thermal Rating Systems utilize a methodology to assess operational thermal rating of equipment such as underground cables, overhead lines and transformers using real-time data of environment conditions and loading rather than conservative assumptions.

The benefits of utilizing RTTR within a proactive, preventative maintenance strategy include:

  • Defer costly upgrades
  • Increase the yield of distributed generation
  • Identification of potential thermal bottlenecks / pinch points
  • Support the network during outages

Real Time Thermal Rating (RTTR) for Power Transmission Cables – What is state of the art?

Bandweaver’s Whitepaper “Real Time Thermal Rating (RTTR) for Power Transmission Cables – What is state of the art?” discusses the evolution of Distributed Temperature Sensing (DTS) and Real Time Thermal Rating (RTTR), where we are today, its uses, benefits and how the operators are implementing this technology.
