Multiapplication protection and control


REX640 is a powerful, all-in-one protection and control relay for advanced power generation and distribution applications. REX640 offers unmatched flexibility throughout its entire life cycle – from ordering through testing and commissioning, to upgrading the functionality of its modular software and hardware to meet new application requirements.

ABB Ability™ smart substation control and protection for electrical systems SSC600 centralizes all protection and control functionality in one single device on distribution substation level for minimal engineering, station-wide visibility and optimal process management. Combining SSC600 with merging units creates an IEC 61850-compliant centralized protection and control solution. The modular software can be flexibly modified for the entire lifetime of the digital substation and allows SSC600 to change with the evolving grid. 


Protection and control REX640

Scope
