RED670 is a line differential protection device produced by ABB. It is suitable for power systems of all voltage levels to protect, control and monitor overhead lines and cables. The RED670 is versatile and flexible to meet the requirements of a wide range of applications. The device uses split-contrast dynamic protection technology, which is highly sensitive to high-resistance faults and provides safe phase selection for up to five line terminals. In addition, the RED670 can also include two or three winding power transformers in the protection range.

Key features and functions of the RED670 include:

It can be used in power systems with different voltage levels, including heavy load lines and multi-terminal lines.
Supports single-phase, two-phase, and three-phase tripping modes.
Provides phase phase protection with excellent sensitivity and phase selection.
Can be used to protect and control overhead lines and cables.
It can be adapted to different network structures, including impedance grounded or directly grounded systems.
It can be used to protect various networks including series compensation systems.
The use of RED670 improves the reliability of power systems and provides integrated protection, control and monitoring solutions. It is part of ABB's Relion family of products designed to meet the high requirements of power system protection.
