REB611 is a special intelligent busbar protection device for the control, monitoring and phase-by-phase protection of single buses against short circuits.
REB611 is used in networks with high impedance earthed neutral in power plant and industrial substations. In addition, it can be used for braking differential and zero sequence protection of generators, motors, transformers and reactors. REB611 has one standard configuration.
After entering the specific parameters, the installed device is ready for commissioning. In addition, the communication and interoperability functionality between substation automation devices that IEC 61850 provides increases flexibility and efficiency for end users as well as power system manufacturers.
