Typical Application Scenarios

Utility Transmission & Distribution Networks: Primary protection for 33kV to 800kV feeders and bus sections where fault clearing speed directly impacts grid stability. The REC670's dual-zone distance protection and directional overcurrent functions provide selective tripping in meshed networks, minimizing outage scope during fault conditions. Utilities report 30-50% reduction in protection-related downtime after REC670 deployment.

Heavy Industrial Power Systems: Motor control centers, generator interconnections, and transformer bays in mining, petrochemical, and manufacturing facilities. The device's arc flash detection capability and personnel safety interlocks comply with NFPA 70E requirements, while remote diagnostics reduce unplanned maintenance visits by 60% in hazardous area installations.

Renewable Energy Grid Integration: Wind farm collector systems and solar inverter stations requiring dynamic grid code compliance (LVRT/HVRT). The REC670's programmable logic enables custom protection schemes for inverter-based resources, addressing voltage ride-through and frequency response mandates in IEEE 1547 and European grid codes.

Critical Infrastructure & Data Centers: Railway electrification substations, airport ground power systems, and Tier III/IV data center electrical distribution where 99.99%+ availability is contractual. The relay's redundant communication ports and hot-swappable power supplies ensure continuous operation during maintenance activities.

Marine & Offshore Platforms: Shipboard power management and offshore oil/gas platform electrical systems exposed to harsh environmental conditions. IEC 60068 compliance for shock, vibration, and salt fog ensures reliable operation in -40°C to +70°C ambient temperatures.

Technical Parameters & Selection Guide

Selection Criteria: When specifying the REC670, consider system voltage class, required protection functions (consult ANSI/IEC standards), communication protocol requirements, and environmental conditions. For applications requiring arc flash detection or synchrophasor measurement (PMU), verify firmware version supports these advanced features. Contact our application engineers for customized I/O configurations and third-party system integration validation.

Extended Functions

IIoT & Predictive Maintenance: Optional integration with ABB Ability™ cloud platform enables condition-based monitoring of circuit breaker operations, contact wear analysis, and thermal overload trending. Machine learning algorithms predict maintenance windows 3-6 months in advance, optimizing spare parts inventory and crew scheduling.

Cybersecurity Hardening: Role-based access control (RBAC), encrypted communication (TLS 1.2), and IEC 62351 compliance protect against unauthorized access and cyber threats. Audit logging tracks all configuration changes and remote access sessions for regulatory compliance (NERC CIP, NIS Directive).

Custom Logic Programming: Built-in IEC 61131-3 logic editor allows creation of site-specific automation sequences without external PLCs—ideal for load shedding schemes, automatic transfer switching, and demand response applications. Pre-validated logic blocks reduce commissioning time by 50%.

Delivery & Service Assurance

Lead Time: Standard configurations ship within 5-7 business days from regional warehouses (SEPOW002EXPU, BRABB002EXPU, INABB005EXPU). Custom I/O builds and firmware pre-configuration require 3-4 weeks. Expedited delivery available for critical outage replacements.

Warranty Coverage: 12-month manufacturer warranty covering defects in materials and workmanship. Extended 36-month warranty packages include firmware updates, remote technical support, and advance replacement service with 24-hour dispatch.

Frequently Asked Questions

Q: How does the REC670 interface with existing SCADA systems running legacy protocols?
A: The REC670 supports simultaneous operation of multiple protocols (IEC 61850 + DNP3 + Modbus) on separate Ethernet ports, enabling phased migration from legacy systems. Protocol gateways are not required for most installations. Our engineering team provides pre-tested SCADA point lists and communication templates for 50+ common DCS/SCADA platforms.

Q: What are the power consumption and heat dissipation specifications for panel thermal design?
A: Typical power consumption is 25W at full load (all I/O active), with maximum dissipation of 30W. The device operates without forced cooling in ambient temperatures up to +70°C. For enclosed panels, allow 150 cm³/min ventilation per device to maintain internal temperature below +60°C.

Q: Can the REC670 achieve sub-cycle fault detection for arc flash mitigation?
A: Yes, the optional arc flash protection function (ANSI 50AF) provides detection and tripping in <2 milliseconds using fiber-optic light sensors. This reduces incident energy levels by 80-90% compared to conventional overcurrent protection, enabling lower-rated PPE for maintenance personnel per NFPA 70E tables.

Q: What cybersecurity measures are required for remote access and firmware updates?
A: The REC670 implements defense-in-depth security: encrypted communication (TLS 1.2), certificate-based authentication, role-based access control, and change audit logging. For NERC CIP compliance, deploy behind utility firewalls with VPN access. Firmware updates require cryptographic signature verification to prevent unauthorized code injection.

Q: How do I migrate settings from legacy electromechanical relays to the REC670?
A: ABB provides a relay replacement guide mapping common electromechanical relay functions (CO-8, IAC-53, HU-17) to equivalent REC670 ANSI functions. Our PCM600 software includes a settings migration wizard that converts time-current curves and pickup values. Typical migration projects require 4-8 hours per bay including validation testing.

Q: Is the REC670 compatible with IEC 61850 Edition 2.1 for process bus applications?
A: The Ver. 1.1 firmware supports IEC 61850 Edition 2 (station bus) with GOOSE and MMS services. Process bus (sampled values per IEC 61850-9-2) requires firmware upgrade to Ver. 2.2 or higher. Contact technical support to verify compatibility with your specific merging unit manufacturers.
