Busbar protection REB650
Version 1.1 ANSI

1. 650 series overview

The 650 series IEDs provide optimum 'off-the-shelf',
ready-to-use solutions. It is configured with complete
protection functionality and default parameters to meet
the needs of a wide range of applications for generation
transmission and sub-transmission grids.
The 650 series IEDs include:
• Complete ready to use solutions optimized for a wide
range of applications for generation, transmission and
sub-transmission grids.
• Support for user-defined names in the local language for
signal and function engineering.
• Minimized parameter settings based on default values
and ABB's new global base value concept. You only need
to set those parameters specific to your own
application, such as the line data.
• GOOSE messaging for horizontal communication.
• Extended HMI functionality with 15 dynamic three-color-
indication LEDs per page, on up to three pages, and
configurable push-button shortcuts for different
actions.
• Programmable LED text-based labels.
• Settable 1A/5A -rated current inputs.

2. Application

The numerical busbar protection REB650 IED provides its
users with a wide variety of application opportunities.
Designed primarily for the protection of single busbars
with or without sectionalizers in high impedance based

applications, it also offers high impedance differential
protection for generators, autotransformers, shunt
reactors and capacitor banks. Its I/O capability allows you
to protect up to three 3-phase high impedance differential
protection zones with a single IED.
A number of additional protection functions are available
for the protection of the bus tie bay. The additional
protection functions include different types of phase and
ground fault overcurrent protection and overvoltage/
undervoltage protection.
One pre-configured package has been defined for the
following application:
• Complete busbar protection for two busbar sections
(zone 1 and 2), with the possibility for check zone (A03A)
For the high impedance differential protection, the
differential current process is made in the analogue
current transformer circuits where the differential current
is connected to the IED via a high ohmic resistor. In
REB650, a current input is used for each phase and
protection zone.
The package is configured and ready for direct use.
Analogue inputs and binary input/output circuits are pre-
defined.
The pre-configured IED can be changed and adapted to
suit specific applications with the graphical configuration
tool.
