Product Details
The ABB REG 670 1MRK002826-AC, also cataloged as the REG670 Generator Protection Panel, operates as a dedicated hardware component for generator and generator-transformer block protection within electrical power generation networks. The system executes real-time evaluation of overcurrent, overvoltage, undervoltage, and phase loss parameters to trigger high-speed protective isolating actions before physical asset thresholds are breached.

Profinet / EtherNet/IP Deterministic Networks Performance
To execute differential protection and phase tracking within sub-cycle intervals, the sampling registers map field telemetry data directly into the internal execution bus. The module layout adheres to specific criteria defining backplane bus communication velocity metrics found across power generation control networks. Hardware expansion routes logic loops through predefined I/O density scaling options, which require absolute firmware flash compatibility between peripheral measurement nodes and the central processor to suppress communication jitter during high-current fault sequences.
Frequently Asked Questions
Q: Can extension cards be inserted or hot-swapped while the REG670 panel remains energized?
A: No. Hot-swapping internal processing cards or I/O modules is prohibited. Auxiliary power must be isolated, and current transformer secondary terminals must be short-circuited externally before any physical module replacement.
Q: How does the device handle false indications caused by transient grid disturbances?
A: The embedded processing platform runs transient filtering algorithms that calculate vector deviations, allowing the logic layer to isolate external temporary anomalies from actual internal block faults.
Q: Is the graphical human-machine interface customizable for specific plant line topologies?
A: Yes. The single-line graphical layout is modified via engineering software tools and loaded directly into the internal non-volatile flash memory array via the front optical or rear network channels.
Field Installation Guidelines
- Low-Impedance Frame Bonding: Secure the 6U rack housing to the panel steel structure using heavy-gauge copper grounding straps. Ensure contact zones are entirely free of paint, scale, or non-conductive coatings to establish zero-potential reference.
- Secondary CT Circuit Interlocks: Route all secondary current transformer wiring through shorting-type terminal assemblies. Never permit an open-circuit path on an active transformer circuit during terminal alterations or installation testing.
- Instrumentation Line Separation: Separate high-speed network copper pathways and analog input conductors from parallel heavy-current alternating current control cables inside the cubicle wireways to prevent induction interference.
