Real Time Thermal Rating (RTTR)
La RTTR (Real Time Thermal Rating, surveillance thermique en temps réel) ou la DCR (Dynamic Cable Rating, surveillance dynamique des câbles) calculent en permanence la température du conducteur en tenant compte de la charge actuelle, de la charge historique, des conditions thermiques et d'un ensemble d'autres facteurs. En même temps, elles prédisent la charge maximale autorisée à l'état stable et dans les situations d'urgence. À partir des normes industrielles IEC 60287 et IEC 60853 et de la modélisation par éléments finis, vous pouvez faire fonctionner votre réseau au plus haut niveau possible de sécurité en matière d'intensité avec d'excellentes capacités prédictives. Le calcul de RTTR est basé sur des modèles thermiques précis qui reflètent les conditions du sol et les conditions ambiantes tout le long du câble d'alimentation à haute tension.
Nous avons collaboré pendant des années avec le leader du marché des logiciels d'évaluation pour obtenir des données précises et fiables. Les résultats d'évaluation sont entièrement intégrés à la plate-forme logicielle SmartVision d'AP Sensing et s'interfacent aisément au centre de répartition des charges des opérateurs via des protocoles standard tels que Modbus TCP, IEC 61850, IEC 60870-104, DNP3 ou OPC.

Underground Transmission Cable Monitoring Pakistan May 2020
AP Sensing is monitoring a 132 kV underground transmission cable for Karachi Electric. This cable experiences greater loads than nominal lines, as it feeds energy to a steel mill with high energy throughputs and frequent consumption cycles. Our solution provides end-to-end temperature monitoring to reduce thermal overload and cable faults. Additionally, RTTR and our asset viewer software enhance operational insight.
Underground Power Cable Utilizing DAS March 2020
An AP Sensing Distributed Acoustic Sensing (DAS) system is monitoring a 6 km high-voltage power cable in Germany. A key feature of DAS is the ability to immediately detect and locate cable faults. This helps optimize transmission and distribution networks, and reduces costly and unnecessary operational costs and asset downtime.
Kriegers Flak Offshore Wind November 2019
Denmark's largest offshore wind farm required a reliable, high-performance solution for protecting and monitoring cable loads and immediately detecting faults. 6 DTS units and 9 DAS units are in use for monitoring 300 km of this asset; AP Sensing's SmartVision visualization software is utilized for a real-time graphic overview of all temperature and acoustic data.
Underground Power Monitoring Skanste Riga Aug 2018
An AP Sensing fiber-optic DTS (Distributed Temperature Sensing) solution was selected to monitor power cables on two underground circuits in Latvia. This successful installation involved one DTS N4425A device with six channels, as well as SmartVision and RTTR (real time thermal rating).
Press Release Fiber Optic Sensing Association NOV 2017
The Fiber Optic Sensing Association (FOSA) today released details on more than 1,300 installations of distributed fiber optic sensing (DFOS) around the world, the largest representative sample ever published. AP Sensing is proud of our global contributions for pipeline leak detection, high voltage power cable monitoring and fire detection.
Offshore Windpark DTS and DAS Monitoring SEPT 2017
The operators of an offshore wind farm located off the west coast of Denmark wanted a monitoring solution to locate cable faults immediately after they occur. They chose AP Sensing for our unique combination of DTS (Distributed Temperature Sensing) and DAS (Distributed Acoustic Sensing) capabilities.
Subsea Power Cable Monitoring with SmartVision and RTTR FEB 2017
The oil platform operator Engie needed a monitoring solution for their medium voltage (35kV) subsea power cable, which provides the power for the platform operations. AP Sensing was selected not only because of our ruggedness, reliability and superior support services, but also for our SmartVision™ and RTTR capabilities.
Subsea Power Transmission Link Sicily Calabria July 2016
The extra high voltage power links run between power stations in Sicily and Calabria, crossing the Messina straits. To monitor and protect the overland sections of this important link, AP Sensing’s fiber-optic based DTS (Distributed Temperature Sensing) solution was selected.
Olympic Park Brazil June 2016
The Olympic Park is the main center of competition for the 2016 Summer Olympics in Rio de Janeiro. Covering over 1 million square meters and including 9 different sports facilities, a new power substation was constructed to handle the enormous power demand in the park. AP Sensing’s fiber-optic based DTS (Distributed Temperature Sensing) solution was selected to monitor this valuable infrastructure.
Wind Park Subsea Power Cable Monitoring Shanghai Oct 2010
The Donghai Bridge Wind Farm in Shanghai is the second largest bridge in the world. The wind farm is the first commercial offshore wind park, and was completed prior to the 2010 World Expo in Shanghai. AP Sensing was selected to monitor the subsea power cable with an approximate length of 15km.
Transmission and Distribution Network Jan 2013
