REB611 is a dedicated busbar protection relay designed for phase-segregated short-circuit protection, control, and supervision of single busbars. REB611 is used in high-impedance-based applications within utility substations and industrial power systems. In addition, this protection relay can be utilized in restricted earth-fault and residual earth-fault applications for the protection of generators, motors, transformers and reactors. REB611 is available in one standard configuration. Scope • Busbar and ideal multipurpose backup protection relay • Product benefits • Preconfigured functions for busbar protection application • The relays are delivered preconfigured and factory-tested to shorten engineering and commissioning time • Self-healing communication based on HSR/PRP using an optional second Ethernet bus • The compact design makes it suitable for both new and retrofit installations • Withdrawable plug-in unit design for swift installation and testing • Product features • Busbar and ideal multipurpose backup protection • Powerful and user-friendly web-browser-based human machine interface (HMI) including input/output (I/O) matrix with visual selections • Application-specific standard configuration resulting in shorter relay setup and commissioning time • Supports IEC 61850 Editions 1 and 2, including binary GOOSE messaging • Pre-configured solutions for utility distribution and industrial applications
