Busbar protection REB650 2.1 IEC
Product version: 2.1

1. Application

The numerical high impedance differential busbar protection
REB650 IED provides its users with a wide variety of
application opportunities. Designed primarily for the
protection of single busbar 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 coupler bay. The additional
protection functions include different types of phase and
earth fault overcurrent protection and over voltage/under
voltage 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 (A03)
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.
Forcing of binary inputs and outputs is a convenient way to
test wiring in substations as well as testing configuration logic
in the IEDs. Basically it means that all binary inputs and
outputs on the IED I/O modules (BOM, BIM and IOM) can be
forced to arbitrary values.
Central Account Management is an authentication
infrastructure that offers a secure solution for enforcing
access control to IEDs and other systems within a substation.
This incorporates management of user accounts, roles and
certificates and the distribution of such, a procedure
completely transparent to the user.
The Flexible Product Naming allows the customer to use an
IED-vendor independent 61850 model of the IED. This
customer model will be used as the IEC 61850 data model,
but all other aspects of the IED will remain unchanged (e.g.,
names on the local HMI and names in the tools). This offers
significant flexibility to adapt the IED to the customers system
and standard solution
