Advanced protection suite: The REF615 HBFFAEAGNBA1ANB1XD incorporates state-of-the-art protection algorithms, such as dynamic load encroachment monitoring, which reduces false trips by 40% in fluctuating industrial loads. In a paper mill’s 20 kV substation, its arc flash protection detected a fault within 2 ms, preventing equipment damage and operator injury while complying with NFPA 70E standards.
Smart grid readiness: With native IEC 61850-90-5 support, the relay enables seamless integration into digital substations, supporting GOOSE messaging for millisecond-level status updates. A utility company used this feature to reduce fault location time by 55%, enabling faster restoration in a 33 kV urban grid. The relay’s built-in web server also allows remote access to phasor measurement unit (PMU) data, supporting grid stability analysis in renewable energy microgrids.
Rugged durability and ease of use: The relay’s hot-swappable design and conformal-coated PCBs ensure reliable operation in high-humidity and corrosive environments. A mining operation in Australia deployed the REF615 HBFFAEAGNBA1ANB1XD in its underground switchgear, where its IP54 rating and vibration resistance (2g sinusoidal) reduced maintenance visits by 30%. The intuitive front-panel HMI and Relion® Manager software simplify commissioning, with auto-calibration features cutting setup time by 50%.
Power transmission and distribution: The REF615 HBFFAEAGNBA1ANB1XD is critical for protecting feeders in smart grids, enabling auto-reclosing functionality to restore power within seconds after transient faults. A major European TSO integrated the relay into its 40.5 kV subtransmission network, achieving a 25% reduction in average outage duration.
Industrial and critical infrastructure: In data centers and healthcare facilities, the relay’s synchronization control ensures seamless transfer between utility and backup power sources. A Tier IV data center used its real-time voltage/frequency monitoring to maintain 99.999% uptime during grid fluctuations, preventing $1M+ losses from server downtime.
Renewable energy integration: For wind and solar farms, the REF615 HBFFAEAGNBA1ANB1XD manages power flow from inverters to the grid, supporting anti-islanding protection and reactive power control. A 100 MW solar plant leveraged its adaptive overcurrent protection to mitigate faults caused by voltage sags during cloud transients, ensuring continuous energy export.
