Product Overview

The ABB RED670 (Order Number 1MRK002810-AB) serves as a high-performance Intelligent Electronic Device (IED) engineered for the current differential protection (87L) of overhead transmission lines and underground utility cables. Part of the elite Relion 670 series, this unit delivers ultra-fast, phase-segregated protection for complex power grid topologies up to 765 kV, including multi-terminal lines and meshed networks. By evaluating time-synchronized current measurements from all ends of the protected terminal zone, it pinpoints internal faults with absolute selectivity.

We guarantee this system component arrives 100% Brand New, factory-original, and ready to secure high-voltage utility assets with advanced digital substation communications.

Engineering Advantages

Resolves Complex Topology Blind Spots: The phase-segregated current differential algorithm evaluates raw local and remote vector data simultaneously. This direct method maintains absolute protection sensitivity across meshed lines and multi-terminal systems where traditional distance relays fail due to variable source impedances.
Integrates Seamlessly into Digital Substation Buses: Native implementation of IEC 61850 Edition 2 allows the relay to broadcast high-speed GOOSE messages and interface directly with process-bus Sampled Values. This integration cuts out copper hard-wiring and accelerates inter-tripping times across the yard.
Neutralizes Current Transformer (CT) Saturation Risks: Advanced internal stabilization logic detects external through-fault currents that saturate physical CT cores. The module dynamically restrains tripping functions during external events, avoiding accidental power outages while remaining fully active for internal faults.
Consolidates Complete Bay Protection Logic: This IED combines primary line differential protection with comprehensive backup functions, including four-step directional overcurrent, full distance protection, breaker failure logic, and multi-shot autoreclosing with built-in synchro-check. This high functional density shrinks total panel space demands.

FAQs

How does the RED670 synchronize current samples across remote line ends?

The 1MRK002810-AB relies on strict microsecond time synchronization to run its differential comparison algorithms. It can calculate channel propagation delays dynamically through dedicated fiber links using echo methods, or sync directly to absolute time via Precision Time Protocol (IEEE 1588 PTP), GPS clock receivers, or IRIG-B inputs.
Can I reconfigure the current input channels from 1A to 5A while the unit is mounted in the panel?

Yes. The current input circuits support both standard 1A and 5A CT secondary ratings. You configure this selection via the PCM600 Protection and Control IED Manager software package; it requires no manual physical wiring modifications inside the terminal terminal array.
What redundancy layout options does the dual fiber-optic network design support?

The dual 100 Mbps fiber ports accommodate redundant station bus topologies using standard Parallel Redundancy Protocol (PRP) or High-availability Seamless Redundancy (HSR) architectures. This configuration ensures that the substation automation platform loses zero data frames if a network switch or individual fiber cable fails.
