The Netherlands, Amsterdam: Optics11 has developed a new approach to asset health monitoring with the introduction of OptiFender – a system designed to improve how utilities detect and respond to insulation faults in critical electrical infrastructure. The technology focuses on identifying partial discharges (PDs), which are often early warning signs of equipment deterioration.
Partial discharges can lead to unexpected breakdowns in transformers, cables, and switchgear. Unlike traditional testing methods, which are periodic and often miss developing faults, OptiFender offers a continuous and automated solution. Using passive fiber-optic sensors that are resistant to electromagnetic interference (EMI), the system listens for acoustic emissions generated by PDs. These signals are then analysed by an AI-powered platform capable of classifying and locating faults with high precision – often within a margin of 15 cm.
This approach eliminates the need for complex recalibration or frequent manual checks. The sensors can be embedded during installation or retrofitted to existing equipment. Once in place, the system requires minimal intervention while delivering ongoing insights into asset condition.
Utilities facing aging equipment and growing network complexity can benefit from OptiFender’s ability to detect problems early, reduce unplanned outages, and shift from reactive to preventive maintenance. Automated alerts and simplified data interpretation make it easier for teams to respond quickly, even without deep expertise in PD analysis.
The system is expected to be available across Europe starting July 2025, with early adoption supported by service providers including Royal SMIT TRANSFORMER SERVICE, Rosh Engineering, and Volta S.p.A.
As energy systems evolve, continuous fault detection tools like OptiFender may become an essential part of keeping infrastructure safe, efficient, and resilient.
