In densely populated areas, the overhead transmission lines have a limit and the chance of faults are great due to outside influencers. If the temperature is monitored in real-time, power transmission capability and reliability can be increased providing maximum capability and cost-effectiveness.
Operating power lines without violating safety codes, the integrity of materials, or network reliability all depend on the transmission line’s real-time rating. If the line is operated at or beyond maximum temperature, this increase in temperature will cause the line to sag and may end up violating design clearances. Through dynamic ratings and real-time monitoring, utilities and operators can develop and apply line ratings based on surrounding conditions like weather conditions and thereby obtain a much more reliable and cost-efficient operation.
With a tailor-made solution from NKT Photonics, you can optimize the use of infrastructure by maximizing the capacity of transmission paths. Data can be used to monitor the load on overhead lines so more power can be transmitted while ensuring safety.
LIOS EN.SURE: A real-time, precise solution for overhead transmission lines
Based on passive optical fibers as temperature sensors, either integrated internally or mounted externally, the LIOS EN.SURE solution provides state-of-the-art temperature measurements in real-time. When linked to the evaluation unit the temperature profile is recorded and processed before transmitted to standard interfaces, in order to provide the operator with valuable operational information. This will limit unnecessary and often risky operator interventions while providing safe and reliable operation above static ratings.
The embedded EN.SURE Conductor Temperature and RTTR system calculates the current-currying capacity under given conditions of the cable and can provide continuous and automatic adjustment of calculation parameters such as ambient temperature, thermal resistivity, etc.
NKT Photonics does not just supply a system but treats every order as a project that requires a full solution. No matter the parameters or design specs of your installation, old or new, there is a solution and we will help you find it.
