Advanced Protection Algorithms
- Multi-Zone Distance Protection (ANSI 21): Up to 5 independent distance zones with quadrilateral or mho characteristics, providing selective fault detection for phase-to-phase and phase-to-ground faults with sub-cycle operating times.
- Directional Overcurrent Protection (ANSI 67): Four-stage directional overcurrent elements with voltage-polarized or current-polarized directional determination, ideal for radial and meshed network configurations.
- Adaptive Protection Logic: Automatic zone reach adjustment based on system conditions, including load encroachment prevention and dynamic fault resistance compensation for evolving fault scenarios.
- Power Swing Blocking (ANSI 68): Intelligent discrimination between stable power swings and genuine faults, preventing unwanted tripping during system oscillations while maintaining security during out-of-step conditions.
- High-Impedance Fault Detection: Specialized algorithms detect high-resistance ground faults that conventional protection may miss, critical for overhead line applications with vegetation contact or broken conductor scenarios.
- Breaker Failure Protection (ANSI 50BF): Integrated backup protection with retriggering logic and remote breaker tripping coordination to ensure fault clearance when primary circuit breakers fail to operate.
Industrial Application Scenarios
- Transmission Line Protection (66kV-500kV): Primary and backup protection for long-distance overhead transmission lines with multi-terminal configurations, series compensation, and parallel line mutual coupling considerations.
- Sub-Transmission Networks (33kV-132kV): Comprehensive protection for urban and industrial sub-transmission systems with cable feeders, mixed overhead/cable circuits, and complex network topologies requiring adaptive protection schemes.
- Renewable Energy Integration: Protection coordination for wind farm and solar plant collector systems, managing bidirectional power flow, low short-circuit levels, and inverter-based resource characteristics.
- Industrial Power Distribution: Critical infrastructure protection for mining, petrochemical, steel, and manufacturing facilities requiring high-speed fault clearing to minimize process disruption and equipment damage.
- Railway Electrification Systems: Specialized protection for AC/DC railway traction power supply networks with unique fault characteristics, harmonic distortion, and dynamic load variations.
- Smart Grid Automation: IEC 61850-based substation automation integration enabling GOOSE messaging, sampled values, and coordinated protection schemes across multiple bays and substations.
Engineering Solutions & Operational Benefits
- IEC 61850 Native Architecture: Full compliance with IEC 61850 Edition 2 including GOOSE, MMS, and Sampled Values (9-2LE), enabling horizontal communication between IEDs and vertical integration with SCADA/EMS systems without protocol conversion.
- Cybersecurity Hardening: Role-based access control (RBAC), encrypted communication (TLS 1.2), event logging, and IEC 62351 compliance protect against unauthorized access and cyber threats in critical infrastructure environments.
- Advanced Disturbance Recording: Continuous waveform capture with pre-fault and post-fault recording (up to 10 seconds), synchronized via IEEE 1588 PTP or IRIG-B for multi-point fault analysis and system-wide event reconstruction.
- Self-Monitoring Diagnostics: Continuous internal health checks including CT/VT circuit supervision, binary input monitoring, output contact verification, and communication link status with automatic alarm generation.
- Flexible Configuration Platform: PCM600 engineering tool provides graphical logic programming, protection setting calculation, IEC 61850 system configuration, and lifecycle asset management from commissioning through decommissioning.
- Reduced Commissioning Time: Auto-configuration wizards, pre-tested protection schemes, and built-in test modes reduce on-site commissioning from days to hours, lowering project costs and accelerating energization schedules.
System Compatibility & Integration
The RED670 relay seamlessly integrates with modern and legacy substation infrastructure:
- ABB Relion® Family: Full interoperability with REF615, RET615, REM615, and other Relion IEDs for coordinated protection schemes and unified engineering workflows

- Legacy Protocol Support: Backward compatibility with DNP3, Modbus, IEC 60870-5-103, and SPA protocols for brownfield retrofit projects
- Time Synchronization: IEEE 1588 PTP (Precision Time Protocol), SNTP, and IRIG-B inputs ensure microsecond-level time stamping for sequence-of-events analysis
- CT/VT Interfaces: Supports conventional instrument transformers (1A/5A, 110V/220V) and non-conventional electronic transformers (NCIT) with low-power inputs
- SCADA/DCS Integration: Real-time data exchange with plant control systems for load management, demand response, and predictive maintenance applications
