Description
System role in substation architecture
Typical installation points:
- Feeder outgoing bays (MV/HV/EHV)
- Bus coupler and bus section bays
- Transformer HV/MV control bays
- Industrial substations with IEC 61850 migration projects
Where older systems rely on copper logic wiring, ABB REC670 1MRK002814-AF shifts logic into configuration files and GOOSE messaging.
That change reduces wiring density but increases engineering dependency on software versions.
