The ABB REL670 Version 2.2 is an advanced numerical overcurrent and earth fault protection relay, designed to provide comprehensive protection, control, and monitoring for medium and high-voltage power systems (-25°C to 70°C). As an upgraded version of the REL670 series, Version 2.2 incorporates enhanced software features, improved communication capabilities, and optimized protection logic, making it ideal for power distribution networks, industrial plants, and utility applications. This rugged, microprocessor-based relay offers precise overcurrent, earth fault, and thermal protection for transformers, motors, feeders, and busbars, ensuring reliable detection of faults (short circuits, overloads, earth faults) and rapid protective actions to minimize equipment damage and downtime. Fully compatible with ABB’s automation systems and industry standards, it features intuitive configuration, advanced diagnostics, and seamless integration with SCADA/DCS platforms, delivering a robust and flexible protection solution for critical power infrastructure.
- Comprehensive overcurrent protection: inverse definite minimum time (IDMT), definite time, and instantaneous overcurrent protection for phase and neutral faults
- Advanced earth fault protection (residual current, directional earth fault) with configurable sensitivity and time settings (Version 2.2 enhanced logic)
- Thermal overload protection for motors and transformers, with temperature modeling and trip curve optimization
- Enhanced communication capabilities (Version 2.2 upgrade): support for IEC 61850 (MMS/GOOSE/SV), Modbus TCP/IP, and DNP3.0 for seamless SCADA integration
- High-precision measurement: current, voltage, power, energy, and frequency monitoring with ±0.2% accuracy
- Configurable relay outputs (Form C SPDT) for fault signaling, circuit breaker tripping, and alarm activation (250V AC/5A rating)
- Built-in self-diagnostics and event logging (up to 1000 events) for fault analysis and predictive maintenance (Version 2.2 expanded logging)
- Secure configuration and firmware updates via ABB PCM600 software, with password protection and access control
- Rugged design with EMI/RFI shielding (85dB attenuation), surge protection (25kV ESD), and IP54-rated front panel for harsh industrial environments
- Compliant with global standards: IEC 60255, IEC 61850, IEEE C37.20.1, UL 508, and CE, ensuring compatibility with international power systems
- Overcurrent and earth fault protection for medium-voltage (MV) feeders in utility power distribution networks
- Motor protection (overcurrent, earth fault, thermal overload) for industrial motors in manufacturing plants, steel mills, and chemical facilities
- Transformer protection (low-voltage side) in power generation plants, cogeneration facilities, and commercial buildings
- Busbar protection in industrial switchgear and distribution substations, preventing cascading faults
- Upgrades from older REL670 versions to Version 2.2 for enhanced communication (IEC 61850) and protection logic in existing power systems
- Oil & gas pipeline power systems, providing reliable fault protection for critical feeder circuits
- Renewable energy (wind/solar) power plants, protecting grid-connected feeders and auxiliary systems
- Water and wastewater treatment plant power distribution, safeguarding pumps, motors, and transformers
- Industrial plant power systems (mining, cement, pulp & paper) requiring robust overcurrent and earth fault protection
Retrofit projects for legacy protection relays, replacing outdated devices with ABB REL670 Version 2.2 for modernized protection and monitoring
