Description

RED670 is one of the ABB Relion series products, specifically designed for power system protection, with model number 1MRK002810-AC specifying its configuration and application scenarios.

Functions and Applications

• Line Differential Protection: RED670 provides phase-segregated differential protection with high sensitivity to high-resistance faults, ensuring the safe operation of overhead lines and cables.

• Backup Distance Protection: In case of communication channel failure, RED670's backup distance protection acts as selective backup protection, ensuring timely clearance of faults.

• Current and Voltage Protection: RED670 is equipped with current and voltage protection functions, monitoring changes in current and voltage in the line and taking appropriate actions in abnormal situations.

• Multi-purpose Protection Functions: Customizable to meet specific user requirements, providing additional backup protections such as multifunctional overcurrent and thermal overload functions.

Technical Features

• Integration: RED670 is an intelligent electronic device integrating protection, control, and monitoring, offering integrated protection, control, and monitoring solutions.

• Phase-segregated Current Differential Protection: RED670's phase-segregated current differential protection features outstanding sensitivity to high-resistance faults and can safely select phases across up to five line terminals.

• Simplified Engineering: RED670 can handle power transformers with two or three windings within its protection scope, simplifying engineering without requiring additional auxiliary equipment.

• Versatility: Supports single-phase, two-phase, and three-phase tripping modes, accommodating different network structures including impedance grounded or directly grounded systems.
