1. Application

REC670 is used for the control, protection
and monitoring of different types of bays in
power networks. The IED is especially
suitable for applications in control systems
with distributed control IEDs in all bays with
high demands on reliability. The IED can be
used up to the highest voltage levels. It is
suitable for the control of all apparatuses in
any type of switchgear arrangements.
The control is performed from remote
(SCADA/Station) through the communication
bus or from local HMI. Different control
configurations can be used, and one control
IED can be used per bay or one IED can be
common for several bays. Interlocking
modules are available for all common types
of switchgear arrangements. The control is
based on the select before execute principle
to give highest possible security. A
synchronism control function is available to
interlock breaker closing. Synchronizing
function where breaker closes at the right
instance in asynchronous networks is also
provided.
A number of protection functions are
available for flexibility in use for different
station types and busbar arrangements. The
auto-reclose for single-, two-, and/or three-
phase reclose includes priority circuits for
multi-breaker arrangements. It co-operates
with the synchrocheck function with high-
speed or delayed reclosing. Several breaker
failure functions are included to provide a
breaker failure function independent from
the protection IEDs, also for a complete one-
and a half breaker diameter.
High set instantaneous phase and earth
overcurrent, 4 step directional or non-
directional delayed phase and earth
overcurrent, thermal overload and two step
under- and overvoltage functions are
examples of the available functions allowing
user to fulfill any application requirement.
Disturbance recording and fault locator are
available to allow independent post-fault

analysis after primary disturbances with a
single failure in the protection system.
6 x 32 dual directional channels for intertrip
and binary signals transfer is available on
each included communication card in the
communication between selected IEDs inside
the station or in a near-by station.
The advanced logic capability, where the user
logic is prepared with a graphical tool, allows
special applications such as automatic
opening of disconnectors in multi-breaker
arrangements, closing of breaker rings, load
transfer logics and so on. The graphical
configuration tool ensures simple and fast
testing and commissioning.
Serial data communication is via optical
connections to ensure immunity against
disturbances.
The wide application flexibility makes this
product an excellent choice for both new
installations and the refurbishment of existing
installations.
Three packages have been defined for
following applications:
• Single breaker (double or single bus)
arrangement (A30)
• Double breaker arrangement (B30)
• 1 ½ breaker arrangement for a complete
diameter (C30)
The packages are configured and ready for
direct use. Optional functions are not
configured but a maximum configuration
with all optional functions is available as
template in the graphical configuration
tool.Interface to analog and binary IO:s are
configurable from the setting tool without
need of configuration changes. Analog and
control circuits have been pre-defined. Other
signals need to be applied as required for
each application. The main differences
between the packages above are the
interlocking modules and the number of
apparatuses to control.
