High-voltage transformer substations (HV and HTA) are undergoing a profound transformation driven by digitalisation, eco-design and integration with smart grids. As a recognised player in modular and sustainable solutions for electrical infrastructure, PREFA FRANCE is fully committed to this technological and environmental revolution.
Digitalisation and automation: intelligent substations
The future of HV substations lies in the complete digitalisation of operations: connected sensors, digital control-command systems according to IEC 61850 standard, and real-time supervision.
PREFA FRANCE designs and integrates ready-to-use “smart” solutions, promoting predictive maintenance, flow optimisation and cybersecurity.
Eco-design and carbon footprint reduction
A pioneer in prefabricated construction with low environmental impact, PREFA FRANCE prioritises eco-designed materials (low-carbon concrete, recyclable components, energy optimisation of processes).
In a context of transition to SF₆-free technologies, the brand supports industry players with substations ready to accommodate air-insulated or ecological gas equipment, meeting sustainability and carbon neutrality requirements.
Smart grids and modularity: PREFA FRANCE flexibility
PREFA FRANCE substations naturally integrate into smart grids, enabling intelligent management of electrical flows, integration of renewable energies and active participation in collective self-consumption.
Benefits of integrated smart grids
- Energy optimisation through real-time flow analysis
- Predictive maintenance via data from connected sensors
- Increased resilience against incidents
- Local energy autonomy for users and industrialists
Artificial intelligence for HV substations
- Machine learning to anticipate energy needs and detect anomalies
- Predictive maintenance to extend equipment lifespan
- Intelligent automation to reduce on-site interventions and enhance safety
Conclusion
By combining technological innovation, energy performance and environmental commitment, PREFA FRANCE establishes itself as a strategic player in the electricity network of the future.
