Cable Monitoring Solutions

Maximizing the utility, increase the operational performance and monitor the cable's health

Electricity is fundamental in today´s world. Power cables have become indispensable for the security of energy supply. Therefore, maximizing the utility of cable assets is both crucial and challenging. Fluctuating demands in different markets and environments, as well as new and renewable sources for energy supply, show the importance of transmitting power to where it is needed. Cable monitoring supports you in maximizing the throughput of your cables, avoiding failures and reducing outage time, as well as prolonging the lifetime of your cable systems.
NKT has over 130 years of experience in the cable industry. Our strategy is to work closely with several suppliers of sensor systems, e.g. fiber optic sensing systems, but also to develop state of the art monitoring systems ourselves, e.g. curvature monitoring described later.
But, the key benefits of a monitoring system comes when you integrate sensors together with real-life knowledge and experience. You need access to the experts to draw the right conclusions and make the right recommendations. NKT has that set of experts.

Distributed Temperature Sensing (DTS)

Employing our temperature sensing technology enables monitoring of the real-time temperature profile along a cable providing valuable data to maximize throughput and provide early detection of potential issues, such as hotspots.
DTS leverages a physical phenomenon in the optical fiber to acurately gauge the temperature of the cable. An optical laser pulse is transmitted through the fiber, with some scattered light returning to the transmitting end for analysis providing a very acurate measurement of the cable's temperature along its length. This information facilitates the detection of hot-spots and enables temporary cable overload in conjunction with a real-time thermal rating system.

Real Time Thermal Rating (RTTR)

RTTR allows temporary cable overloading by acurately predicting temperature evolution under various loads. Use RTTR to increase the utility of your cable by exceeding its rating when power is needed.
