Brief Product Description

RED670, part number 1MRK002810‑AC, is a high‑performance line distance protection relay within ABB Relion 670 series, specially designed for transmission and distribution power line protection. This intelligent IED integrates distance protection, fault location, auto‑reclosing and multiple auxiliary protection functions. It supports IEC 61850, MMS and GOOSE communication for substation automation systems. Equipped with powerful fault recording and event logging capabilities, it delivers fast, reliable tripping responses under various grid fault conditions. With robust hardware for substation cabinet installation, it serves as critical spare equipment. Supplied as fully‑tested surplus and refurbished units for maintenance and retrofitting of existing power substation protection systems.

Core Product Functions

• High‑speed distance main protection for overhead transmission and distribution power lines
• Multiple backup protection functions including over‑current, earth‑fault and negative‑sequence protection
• Built‑in auto‑reclosing function to restore power supply after transient line faults
• Accurate fault location function to calculate fault distance for quick field troubleshooting
• Comprehensive disturbance recorder for capturing fault waveforms, event logs and sequence‑of‑events records
• Support IEC 61850 (GOOSE, MMS), Modbus and IEC 60870‑5‑103 substation communication protocols
• Local HMI panel for parameter setting, status monitoring and fault information checking on‑site
• Flexible configurable logic for adapting to different power grid operation modes

• Hardware self‑supervision function to detect internal IED failures and output alarm signals

Application Scenarios

• Transmission substation protection and control for high‑voltage overhead power lines
• Distribution network substations requiring distance protection and auto‑reclosing functions
• Industrial power plant outgoing line protection for generator step‑up and auxiliary power systems
• Renewable energy station grid‑connection protection cabinets for wind farm and solar power plants
• Smart substation projects adopting IEC 61850 Relion 670 series automation framework
• Spare replacement protection IED for maintenance, troubleshooting and upgrade of legacy ABB substation protection systems

FAQ (Frequently Asked Questions)

• Q: Relay cannot communicate with substation host system after replacement?
  A: Check network wiring, IP address configuration, IEC61850 / protocol parameter settings and hardware communication port status.
• Q: IED keeps reporting self‑supervision alarm after power‑on?
  A: Inspect power supply input, module backplane contact, configuration file consistency or internal hardware component failure.
• Q: Can ABB RED670 1MRK002810‑AC be hot‑swapped under live substation cabinet condition?
  A: Hot‑swap is not allowed. Follow power safety procedures, isolate secondary circuits before replacement to avoid mis‑operation risk.
• Q: Can this distance protection relay work with non‑ABB substation automation systems?
  A: It supports standard IEC61850 protocols, but complete protection logic and configuration tools are ABB proprietary; full compatibility with third‑party systems cannot be guaranteed.
• Q: Is ABB RED670 1MRK002810‑AC available for brand‑new substation projects?
  A: This legacy protection IED has reached end‑of‑life. Only surplus and fully‑tested refurbished units are provided for existing‑site maintenance and retrofit tasks.
