Technical Parameters of ABB RED670 Transmission Line Differential Protection Module

The ABB RED670 is an advanced intelligent electronic device (IED) designed for the protection, control, and monitoring of transmission lines, cables, and transformer feeders in all types of networks. Below are its key technical specifications:

1. General Specifications

Model: RED670
Function: Transmission line differential protection, distance protection, and advanced monitoring for overhead lines, cables, and transformer feeders.
Application Range: Suitable for distribution up to the highest voltage levels, including multi-terminal and heavily loaded lines.

2. Protection Functions

Differential Protection:
- Phase-segregated current differential protection with up to six stabilized current inputs per phase.
- Supports up to 5 line terminals (3-5 terminals in multi-breaker arrangements).
- Includes high-impedance differential protection (PDIF, 87X) for T-feeders or line reactors.
Distance Protection:
- Full-scheme phase-to-phase and phase-to-earth distance protection with up to three zones.
- Includes load encroachment feature for enhanced fault detection under heavy load conditions.
Auto-Reclosing:
- Supports single-, two-, and/or three-phase reclosing with priority circuits for multi-breaker arrangements.

3. Communication

Protocols:
- Compliant with IEEE C37.94 standard for redundant communication between IEDs.
- Supports IEC 61850-8-1, IEC 60870-5-103, LON, and SPA protocols.
Channels:
- 8 channels for intertrip and binary signals between IEDs.
Time Synchronization:
- Supports echo-method or built-in GPS for precise time synchronization.

4. Performance

Accuracy:
- Analog measurement accuracy: <0.5% for power and <0.25% for current and voltage (with site calibration).
Stability:
- Separate inputs for each CT in double-breaker, ring, and one-and-a-half-breaker installations for improved through-fault stability.

5. Monitoring & Diagnostics

Event Recorder:
- Integrated disturbance and event recorder for up to 40 analog and 96 binary signals.
Self-Supervision:
- Extensive self-monitoring with internal event recorder and human-machine interface (HMI).

6. Configuration & Flexibility

Setting Parameters:
- Six independent groups of complete setting parameters with password protection.
Software Tools:
- Powerful PC software tool for setting, disturbance evaluation, and configuration.
Expandability:
- Modular hardware design for scalability to meet specific user requirements.

7. Physical & Environmental Specifications

Dimensions:
- Typically designed for panel mounting with a compact form factor (specific dimensions may vary based on configuration).
Operating Conditions:
- Temperature range: -25°C to +70°C (compliant with industrial standards).
- Humidity: 5% to 95% RH (non-condensing).

8. Optional Features

Additional Software Functions:
- Includes distance protection, control, and monitoring functions that can be selected and configured as needed.
Transformer Protection:
- Capability to include power transformers in the protected zone with automatic CT ratio matching and vector group compensation.

9. Certifications & Compliance

Standards:
- Compliant with international standards such as IEC 61850, IEEE C37.94, and others relevant to power system protection and automation.

The RED670 module is designed to provide robust and flexible protection for transmission lines and cables, offering advanced features such as multi-terminal differential protection, distance protection, and comprehensive monitoring capabilities. Its modular design and support for multiple communication protocols make it suitable for a wide range of applications in power systems.
