Product Overview
The ABB RED670 1MRK002810‑AC is a high‑performance protection IED from the Relion 670 series, built for overhead transmission lines and cable lines in power utility and industrial power systems. It delivers high‑speed phase‑segregated line differential protection supporting up to five‑terminal line configurations, and integrates distance protection, back‑up overcurrent protection, control, metering, event logging and fault disturbance recording in a single unit. This device is widely used for new build projects in the past and now serves as critical replacement spare for existing substation retrofits and maintenance work worldwide.
Series
RED670 belongs to ABB Relion® 670 protection and control IED family. The Relion 670 series adopts modular hardware architecture, allowing flexible function configuration via software licensing without changing hardware modules. This series covers line, transformer, generator and bay control applications, supports multiple industry standard communication protocols, and complies with international IEC power‑protection standards for substation automation system integration.

Purpose
The ABB RED670 1MRK002810‑AC IED is intended for primary and backup protection, control and monitoring of transmission and sub‑transmission overhead lines and power cables. It ensures fast and reliable fault isolation to maintain power grid stability. Presently it is mainly deployed as spare replacement unit for legacy ABB Relion 670 series installed base during substation upgrade and maintenance projects.
Application Fields
- Power utility transmission and sub‑transmission substations, overhead line & cable bay protection
- Thermal power plant, hydropower plant outgoing transmission line protection
- Petrochemical, mining, large‑scale heavy‑industry plant internal high‑voltage power network
- Multi‑terminal transmission line projects, series‑compensated power line applications
- Legacy substation modernization, retrofit and spare‑part replacement for existing Relion 670 installations
