Description

ABB REC670 1MRK002814-AB Product Overview

Basic Information

Key Features

1. Protection Functions
   • Core Functions:
     • Overcurrent protection (instantaneous, time-overcurrent, directional overcurrent).
     • Earth fault protection (sensitive ground fault detection).
     • Voltage protection (undervoltage, overvoltage, voltage unbalance).
     • Distance protection (for transmission lines, depending on configuration).
   • Flexible Settings: Programmable via ABB’s Relion® software (e.g., setting curves, time delays, pickup values).
2. Communication and Networking
   • Protocols:
     • IEC 61850 (GOOSE, SV) for smart grid integration.
     • Modbus RTU/TCP, DNP3 for legacy systems.
   • Interfaces:
     • Ethernet (10/100 Mbps), RS-485, USB for configuration and diagnostics.
     • Support for redundant communication networks (e.g., dual Ethernet ports).
3. Control and Monitoring
   • Remote Control: Remote switching of circuit breakers, isolators, or switches via SCADA systems.
   • Event Logging: High-resolution event records (≤1 ms accuracy) for fault analysis.
   • Real-Time Monitoring: Measures voltage, current, power (active/reactive), frequency, and harmonic content.
4. Mechanical and Environmental
   • Form Factor: Compact design for panel or rack mounting (dimensions typically ~220 mm × 170 mm × 150 mm).
   • Operating Temperature: -25°C to +60°C (standard); extended ranges (-40°C to +70°C) available.
   • EMC Immunity: Meets IEC 61000-6-2 (industrial environment) and IEC 61010-1 (safety for electrical equipment).
   • Vibration/Shock Resistance: Compliant with IEC 60068-2-6 (vibration) and IEC 60068-2-27 (shock).
5. Diagnostics and Maintenance
   • Self-Test Functions: Built-in diagnostics for hardware faults (e.g., CPU, memory, I/O).
   • Auto-Calibration: Internal calibration for measurement accuracy.
   • Hot-Swap Capability: Optional for field replacement without power disruption.

Typical Applications

• Power Distribution Systems:
  • Protection of MV/LV transformers, feeders, and motors in substations.
  • Example: In a utility substation, the REC670 protects a 110 kV feeder from overcurrent faults and communicates trip signals via IEC 61850.
• Industrial Power Plants:
  • Motor protection in critical machinery (e.g., pumps, compressors) in oil & gas, mining, or manufacturing.
  • Example: In a petrochemical plant, the relay monitors a large motor for phase unbalance and initiates a shutdown if a fault is detected.
• Renewable Energy Grids:
  • Protection for solar/wind farm inverters and grid interconnection points.
  • Example: In a wind farm, the REC670 ensures safe islanding detection and voltage regulation during grid outages.
• Smart Grid Integration:
  • Part of ABB’s digital substation solutions, supporting peer-to-peer communication (GOOSE) and seamless integration with supervisory control systems.
