ABB RET670

2. Functional Features

• Core Protection Functions:
  • Overcurrent, under/overvoltage, overfrequency/underfrequency protection.
  • Differential protection for transformers, generators, and cables.
  • Ground fault and thermal overload protection.
• High-Precision Measurement:
  • Advanced digital signal processing (DSP) for accurate current/voltage measurement (±0.5% accuracy).
• Fast Response Time:
  • Sub-cycle operation (e.g., <20 ms for differential protection) to minimize fault duration.
• Flexible Configuration:
  • Software-programmable settings for custom protection schemes.
  • Supports logic programming for automation sequences.
• Event Logging & Alarms:
  • Built-in event recorder with COMTRADE format export for fault analysis.
• Remote Monitoring & Control:
  • HMI with color LCD/touchscreen for local operation.
  • Web-based interface for remote access.

3. Application Scenarios

• Power System Protection:
  • Safeguards transformers, generators, cables, and feeders in substations and power plants.
• Industrial Automation:
  • Integrates with DCS/SCADA systems for process control in manufacturing, oil & gas, and renewable energy.
• Renewable Energy:
  • Protects inverters and grid-connected systems in solar/wind farms.
• Critical Infrastructure:
  • Used in water treatment, transportation, and building automation for reliability.

4. Supported Industrial Protocols

• IEC 61850: Standard for substation automation, enabling seamless integration with modern DCS/SCADA.
• Modbus RTU/TCP: Serial and Ethernet-based communication for legacy system compatibility.
• DNP3: Supports distributed automation in utility networks.
• PROFINET/EtherNet/IP: Real-time data exchange in industrial Ethernet environments.
• Custom Protocols: Configurable via ABB engineering tools (e.g., Control Builder).

5. Extensibility & Scalability

• Modular Design:
  • Supports additional I/O modules (e.g., analog/digital inputs/outputs) for future expansion.
• Multi-Device Integration:
  • Cascadable with other RET670 units or ABB protection devices (e.g., REF615, REL615).
• Software Customization:
  • Programmable via ABB System 800xA or third-party tools for tailored logic.
• Industrial Network Compatibility:
  • Integrates with ABB Symphony Plus, 800xA, and third-party DCS/PLC systems.
• Flexible Mounting:
  • DIN rail or panel mounting for space-efficient installation.

6. Advantages

• High Reliability: Built for 24/7 operation in harsh environments.
• Precision & Stability: Ensures accurate protection for critical assets.
• Durability: Robust construction minimizes downtime.
• Ease of Use: Simplified installation, configuration, and maintenance.
