Dynamic Cable Rating

Dynamic Cable Rating system continuously monitors all points along the network, providing real time temperature measurement and dynamic thermal rating calculations. Sensornet cable rating calculates conductor temperature at all points along the cable and can predict cable rating over the short and medium term.

Offline cable rating solutions are based on static models and cannot take into account changing environmental conditions (e.g. soil thermal resistivity, change in ambient temperature). In the event you need to increase load in emergency situations or system maintenance, you are not able to actively measure if the cable rating is being exceeded. Conventional DTS technology can not offer the temperature resolution required for dynamic cable rating at long distances.

With conventional technology there is a gap between what the operator believes is occurring in the network and what is actually happening. This can result in reduced asset lifetime, or in severe cases cause system failures such as hot spots, fire, or insulation breakdown. Sensornet’s revolutionary technology overcomes the limitations of measurement technologies available today thus closing the monitoring gap and improving system integrity and safety.

  • Full coverage of long distance power cables with continuous monitoring for up to 200 kilometres per DCR
  • Respond dynamically in emergency rating situations to predict cable ratings over a 48 hour period
  • Detect temperature changes of less than 0.1˚C for accurate dynamic rating systems
