Real Time Thermal Rating (RTTR) or Dynamic Cable Rating (DCR) continuously calculates the conductor temperature of a power grid by taking current load, load history, thermal conditions and other factors into account. At the same time it predicts the maximum permissible load for steady state and emergency situations.

This article 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.

Develop smart grids and get maximum power output with on-line Distributed Temperature Sensing (DTS) and Real-Time Thermal Rating (RTTR) for your land or submarine transmission links.

DTS monitors onshore cable temperature in real-time. It helps in identifying hot-spots and enables temporary overload with a real-time thermal rating. Maximize utility of your cables with our RTTR system, which anticipates cable temperature evolution under various loads.

The RTTR system calculates the corresponding conductor temperature for each thermal zone and determines the maximum permanent current for each zone. The RTTR provide an overview of the 5 most critical zones of the cable system and a history …

Real Time Thermal Rating is a methodology used within the power and utility sector to assess operational thermal rating of equipment, i.e. the maximum amount of electrical current that a transmission line or electrical facility can conduct before …

The core of our cable monitoring system is the RTTR software, also known as Dynamic Cable Rating (DCR). This proprietary calculation and visualization software precisely calculates the conductor temperature at every point within the cable system and presents the results in a clear, graphical format for the user.

2022年12月9日 · The DTS continuously measures the real-time temperature at the sheath or jacket of the cable. This data, combined with the cable’s load, is continuously fed into a Real Time Thermal Rating (RTTR) or Dynamic Cable Rating (DCR) engine and individually modeled per thermal section. This provides both steady-state and transient thermal analysis.

2012年1月1日 · The DTS system is based on the monitoring and the accurate determination of the temperature position and value on each point along a fibre optic cable. With state of the art available devices, it is possible to continuously measure temperatures variations of less than 1 K over a length of more than 50 km with a precision of the order of 1 m.
