REF611 Feeder Protection and Control

REF611 is a dedicated feeder IED(intelligent electronic device) designed for the protection, control, measurement and supervision of utility substations and industrial power systems including radial, looped and meshed distribution networks with or without distributed power generation. REF611 is a member of ABB’s Relion® product family and part of the 611 protection and control product series. The 611 series IEDs are characterized by their compactness and withdrawable-unit design.
The 611 series is designed to offer simplified, but powerful functionality intended for most applications. Once the application-specific parameters have been entered, the installed IED is ready to be put into service. The further addition of communication functionality and interoperability between substation automation devices offered by the IEC 61850 standard adds flexibility and value to end users as well as electrical system manufacturers.
2. Standard configurations
REF611 is available in two alternative standard configurations.
To increase the user friendliness of the IED’s standard configurations and to emphasize the IED’s simplicity of usage, only the applicationspecific parameters need setting within the IED’s intended area of application.
The standard signal configuration can be altered by LHMI (human-machine interface), WHMI (Web browser-based user interface) or the optional application functionality of the Protection and Control IED Manager PCM600.
