Substation Automation & Control Logic
As a cornerstone of the Relion® 670 platform, theREC670 1MRK002810-ABexcels in multi-object control environments. It is capable of managing complex interlocking schemes for circuit breakers and disconnectors across multiple bays. The device's support for IEC 61850 GOOSE messaging allows for hardware-independent protection coordination, significantly reducing the need for copper wiring between panels. This IED is not only a protection device but a comprehensive controller that provides synchronized measurements and disturbance recording for post-fault analysis in utility-scale grids.
