The ABB REB670 1MRK002820-AC is a feeder protection device designed for the protection and monitoring of medium- and high-voltage busbars, T-junctions, and mesh corners. The following is a detailed description:
Features
High-speed differential protection: Equipped with high-speed differential protection, it provides selective, reliable, and rapid fault clearing for busbars, T-junctions, and other locations, and can quickly detect and isolate internal phase-to-phase and phase-to-ground faults.
Flexible zone selection: Integrated with flexible dynamic zone selection, it enables dynamic connection of current transformers to different busbar protection zones. It also provides selective busbar protection, circuit breaker failure tripping, and condition monitoring for disconnectors and circuit breakers.
Multiple communication protocol support: Support for multiple communication protocols, including IEC 61850, Profibus, and DNP 3, facilitates communication and integration with other devices and systems, enabling rapid data transmission and interaction.
Event logging: A comprehensive event logger records relevant event information for fault analysis and system maintenance. Compliance with International Standards: Adherence to the IEC 61850 standard ensures an open, future-proof, and flexible system architecture.
Technical Specifications: The operating voltage range is typically 110V AC to 250V AC. The device's current measurement range is typically 0.2-40 times the rated current. Its fault logging function provides high-resolution event recording.
Applications: Suitable for power plants, substations, and industrial facilities, it can protect a variety of busbar configurations, including single busbar, double busbar with or without transfer busbars, and double-breaker or one-and-a-half-breaker configurations.
