Sterlumiq, the joint venture between Sterlite Electric and RDT Lumiker and a provider of advanced cable monitoring technologies, has entered into a strategic commercial and technology partnership with AP Sensing, a global leader in Distributed Fiber-Optic Sensing (DFOS) solutions, to develop and commercialise integrated monitoring solutions for power cable and overhead line (OHL) networks worldwide.
The collaboration combines AP Sensing’s expertise in Distributed Acoustic Sensing (DAS), Distributed Temperature Sensing (DTS) and Distributed Temperature and Strain Sensing (DTSS) with Sterlumiq’s Cable Advanced Monitoring Optical System (CAMOS) and electrical current sensing technologies. The integrated solution is designed to provide utilities, transmission system operators (TSOs), renewable energy developers and other network owners with comprehensive visibility into cable health, operational performance and potential risks through a unified monitoring platform.
By integrating thermal, acoustic, strain and electrical monitoring data, the partnership aims to enhance fault detection, improve asset utilisation and strengthen the reliability and resilience of electricity transmission networks.
Commenting on the partnership, Manuel Munoz Luengo, CEO of Sterlumiq, said, “Both DFOS and CAMOS provide different but highly complementary perspectives on cable behaviour. Distributed sensing allows us to observe temperature, acoustic activity and strain across the cable route, while CAMOS adds direct intelligence from phase and screen-current measurements. Correlating these signals can provide a much deeper understanding of asset condition, fault behaviour and available capacity, enabling utilities to shift from isolated alarms and reactive interventions towards predictive, condition-based network management.”
Dr Henrik Hoff, Business Director at AP Sensing, highlighted the growing importance of intelligent grid monitoring amid the global energy transition. “The global energy market is going through an incredibly exciting and dynamic phase. Working with Sterlumiq helps us to develop innovative solutions that make transmission networks safer, more powerful, and more resilient. We have many ideas that we can now implement with our partner for the benefit of our customers. With fiber-optic sensors for thermal, acoustic and now also electrical conditions, we provide a comprehensive solution package that addresses the main challenges in energy transmission,” he said.
The partnership will initially focus on regional cross-selling opportunities while integrating the companies’ respective monitoring technologies and analytics into scalable solutions for high- and medium-voltage cable networks. Beyond commercialisation, Sterlumiq and AP Sensing will jointly collaborate on product development, technical validation, customer support and international deployment of next-generation asset monitoring systems.
As utilities worldwide modernise their transmission infrastructure and integrate increasing levels of renewable energy, the demand for predictive, condition-based monitoring solutions continues to grow. The Sterlumiq–AP Sensing alliance is expected to strengthen grid operators’ ability to improve network reliability, optimise asset performance, and reduce operational risks through advanced data-driven intelligence.
