ABB RED670 is a numerical line differential protection relay engineered for transmission and sub-transmission power networks. As a member of the ABB Relion® 670 protection family, it delivers fast and selective fault clearance while maintaining reliable operation under demanding grid conditions.

The relay supports line differential protection, distance protection, overcurrent protection, fault monitoring, control logic, event recording, and communication functions. It is designed to protect overhead lines, cable feeders, and complex multi-terminal systems where dependable protection is critical.

ABB RED670 utilizes advanced communication and synchronization technologies to compare current measurements across protected zones, helping detect internal faults with high sensitivity while maintaining stability during external disturbances. This makes it suitable for modern utility networks, substations, renewable energy integration projects, and industrial power systems.
