Description
Application Scenarios:In a critical 110/20 kV primary distribution substation, operators need immediate visibility and control over circuit breaker status, load currents, and fault events to maintain grid stability. The ABB REC670 1MRK000008-NB is deployed as the central intelligence for a transformer bay. It continuously monitors currents and voltages via connected instrument transformers, executing protection functions like differential and overcurrent protection. Its integrated display provides operators with real-time single-line diagrams, metering values, and event lists directly at the switchgear panel. This addresses key pain points of operational delay and complexity by eliminating the need to connect a laptop for basic data, allowing for rapid local switching, fault diagnosis, and restoration, significantly enhancing substation responsiveness and safety.

Technical Principles and Innovative Values:The ABB REC670 1MRK000008-NB represents a convergence of multiple substation functions into a single, highly capable device, built on a modern hardware and software platform.
- Integration of Protection & Control (PACi): The REC670 seamlessly merges traditional protection relay functions with advanced bay control, interlocking, and automation logic. This innovation reduces panel footprint, wiring, and device count, while simplifying engineering and testing. The single IED handles complex schemes like synchrocheck and auto-reclosing alongside primary protection.
- IEC 61850 Native Architecture: The device is designed from the ground up for the IEC 61850 standard. It supports high-speed GOOSE messaging for inter-IED communication and MMS for SCADA integration. This enables advanced, interoperable substation automation schemes, replacing hardwired signals with digital communication for increased flexibility and reduced cabling.
- Advanced Condition Monitoring & Local HMI: Beyond basic protection, the REC670 performs detailed disturbance recording, event logging, and condition monitoring (e.g., circuit breaker wear). The integrated 1MRK000008-NB variant’s local display provides immediate, on-site access to this data, waveforms, and settings, empowering field technicians to perform diagnostics and basic operations without external tools, drastically reducing troubleshooting time.
