Product Description

The RED670 (1MRK002810-AB) is a high-performance line differential protection relay from ABB’s Relion® 670 product family. It provides ultra-fast, selective, and secure protection for overhead lines and underground cables in transmission and sub-transmission networks—especially in multi-terminal or meshed configurations where traditional overcurrent schemes are insufficient.

Using time-synchronized current measurements from both ends of a protected line via IEC 61850-9-2 LE (sampled values) or legacy fiber-optic links, the RED670 detects internal faults within milliseconds while remaining stable during external disturbances, CT saturation, or inrush conditions.

Technical Specifications

Manufacturer: ABB
Model / Part Number: RED670 (1MRK002810-AB)
Product Series: Relion® 670
Primary Function: Line current differential protection
Standards Compliance: IEC 61850 Edition 2, IEEE C37.94, IEC 60255
Communication Interfaces:

Dual 100 Mbps Ethernet (IEC 61850-9-2 LE, GOOSE, MMS)
Optional fiber-optic serial link (for legacy differential schemes)
IRIG-B, PTP (IEEE 1588), or SNTP for precise time sync

Sampling Rate: Up to 4 kHz per channel
Operating Voltage: 24–250 VDC or 100–240 VAC (universal auxiliary supply)
Application Range: Up to 400 kV systems
Mounting: 19" rack, 6U height
Origin: Designed and manufactured in Europe (typically Sweden or Finland)

Typical Applications

Protection of critical transmission feeders between substations
Cable circuits in urban distribution networks
Tie-lines in industrial power systems requiring high-speed tripping

FAQ
Q: Does it require GPS at both line ends?
A: Not necessarily—time synchronization can be achieved via PTP over IEC 61850 networks or IRIG-B from a local master clock. GPS is one option but not mandatory.

Q: How does it differ from the REL670?
A: The REL670 is a general-purpose line distance/overcurrent relay; the RED670 specializes exclusively in current differential protection with advanced stabilization algorithms.

Q: Can it work with non-ABB relays at the remote end?
A: Yes—if the remote device supports interoperable sampled values (IEC 61850-9-2 LE) or compatible differential protocols (e.g., IEEE C37.94 over fiber).
