Product Overview
The ABB REC670 is a high-performance,multifunctional protection and control relay engineered for utility substations and industrial power systems requiring advanced feeder,motor,or transformer protection.As part of ABB’s Relion®product family,the ABB REC670 integrates comprehensive protection,monitoring,control,and communication capabilities into a single,compact IED(Intelligent Electronic Device),enabling utilities and large industrial operators to enhance grid reliability,reduce outage durations,and comply with modern smart grid standards.Designed for applications ranging from 11 kV distribution feeders to critical motor drives in oil&gas or mining facilities,the ABB REC670 delivers sub-cycle fault detection,adaptive protection logic,and seamless interoperability within ABB’s System 800xA or third-party SCADA environments via IEC 61850.
Unlike legacy electromechanical relays or basic digital units,the ABB REC670 leverages a dual-processor architecture—one dedicated to real-time protection algorithms,the other to communication and HMI tasks—ensuring deterministic response even under heavy network load.Its modular design supports flexible configuration through PCM600 engineering tool,allowing engineers to activate only the required functions(e.g.,distance protection,differential,arc flash detection)without hardware changes.With built-in cybersecurity features(IEC 62351 compliance),waveform capture,and event recording aligned with IEEE C37.111(COMTRADE),the ABB REC670 not only prevents equipment damage but also provides forensic data for root-cause analysis after disturbances.Trusted in thousands of installations worldwide—from wind farms to metro traction networks—the ABB REC670 represents ABB’s commitment to resilient,future-ready power protection.

Main Features and Advantages
Advanced Protection with Adaptive Logic:The ABB REC670 goes beyond fixed-setpoint tripping by offering adaptive protection schemes—such as load-responsive overcurrent or voltage-dependent distance zones—that automatically adjust to system conditions,minimizing nuisance trips during transients while maintaining sensitivity during actual faults.
Full IEC 61850 Native Support:As a true IEC 61850 Edition 2-compliant device,the ABB REC670 supports GOOSE messaging for ultra-fast interlocking(e.g.,breaker failure backup),Sampled Values(SV)for merging unit integration,and MMS for SCADA communication—all over a single Ethernet port.This eliminates protocol converters and simplifies substation automation architecture.
Integrated Arc Flash Detection:Optional fiber-optic arc sensors can be directly connected to detect dangerous arc flash events within switchgear in<1 ms,triggering instantaneous trip commands to limit energy release and protect personnel—a critical feature for medium-voltage metal-clad switchboards.
Comprehensive Diagnostics and Cybersecurity:Built-in self-monitoring tracks relay health(power supply,memory,communication),while role-based access control,audit logging,and encrypted firmware updates(per IEC 62351)ensure secure remote access—essential for NERC CIP or ISO 27001 compliance.
Unified Engineering with PCM600:Protection logic,HMI mimic diagrams,and communication mappings are configured in a single project file using ABB’s PCM600 tool,drastically reducing commissioning time and eliminating configuration mismatches between devices.
Application Field
The ABB REC670 is deployed across a wide spectrum of power infrastructure where reliability,selectivity,and digital integration are paramount.In utility distribution networks,it protects overhead and underground feeders with directional overcurrent and sensitive earth-fault detection,enabling faster isolation of permanent faults and supporting automated restoration schemes.Within industrial complexes—such as refineries,steel mills,or data centers—the ABB REC670 safeguards critical motors(up to 20 MW)with thermal overload modeling,phase imbalance,and bearing temperature monitoring,preventing costly unplanned shutdowns.
It is also extensively used in renewable energy plants:in solar farms for collector feeder protection,and in wind turbines for generator and step-up transformer backup.Railway traction substations rely on the ABB REC670’s negative-sequence overcurrent and frequency protection to handle unbalanced loads from locomotives.Additionally,its support for breaker monitoring(via optional I/O modules)makes it ideal for circuit breaker health assessment in aging infrastructure upgrades.Whether replacing electromechanical relays in a 1970s substation or serving as a core IED in a greenfield smart grid project,the ABB REC670 delivers scalable protection intelligence that grows with evolving operational needs.

Installation and Maintenance
Pre-installation preparation:Before installing the ABB REC670,verify that the CT/VT ratios and auxiliary supply voltage match the engineering settings in PCM600.Ensure Ethernet switches support VLAN tagging if used in an IEC 61850 process bus,and confirm that time synchronization(IRIG-B or SNTP)is available for event alignment.Mount the relay on a standard 19-inch rack or panel using the provided brackets,allowing at least 50 mm clearance for ventilation and cable routing.
Maintenance recommendations:Perform annual functional tests using secondary injection to validate protection curves and trip times.Regularly back up the ABB REC670 configuration via PCM600 and review event records for abnormal operations(e.g.,frequent pickup without trip).Inspect fiber-optic arc sensor connections for dust or bending losses if installed.Firmware updates should only be applied after compatibility verification with the existing system version and during scheduled outages.The relay’s front-panel HMI allows local status checks without a laptop,but full diagnostics require PCM600 or ABB’s web-based interface.
