Synchrocheck, energizing check, and synchronizing
SESRSYN
The Synchronizing function allows closing of
asynchronous networks at the correct moment including
the breaker closing time, which improves the network
stability.
Synchrocheck, energizing check, and synchronizing
(SESRSYN) function checks that the voltages on both
sides of the circuit breaker are in synchronism, or with
at least one side dead to ensure that closing can be
done safely.
SESRSYN function includes a built-in voltage selection
scheme for double bus arrangements.
Manual closing as well as automatic reclosing can be
checked by the function and can have different settings.
For systems which are running asynchronous a
synchronizing function is provided. The main purpose of
the synchronizing function is to provide controlled
closing of circuit breakers when two asynchronous
systems are going to be connected. It is used for slip
frequencies that are larger than those for synchrocheck
and lower than a set maximum level for the
synchronizing function.
Autorecloser SMBRREC
The autorecloser (SMBRREC) function provides high-
speed and/or delayed auto-reclosing for single breaker
applications.
Up to five reclosing attempts can be included by
parameter setting.
The autoreclosing function can be configured to co-
operate with a synchrocheck function.
Autorecloser STBRREC
The autoreclosing function provides high-speed and/or
delayed auto-reclosing for single breaker applications.
Up to five reclosing attempts can be included by
parameter setting. The first attempt can be single-
and/or three phase for single-phase or multi-phase
faults respectively.
Multiple autoreclosing functions are provided for multi-
breaker arrangements. A priority circuit allows one
circuit breaker to close first and the second will only
close if the fault proved to be transient.
The autoreclosing function can be configured to co-
operate with a synchrocheck function.

Bay control QCBAY
The Bay control QCBAY function is used together with
Local remote and local remote control functions is used
to handle the selection of the operator place per bay.
QCBAY also provides blocking functions that can be
distributed to different apparatuses within the bay.
Local remote LOCREM /Local remote control
LOCREMCTRL
The signals from the local HMI or from an external local/
remote switch are applied via the function blocks
LOCREM and LOCREMCTRL to the Bay control (QCBAY)
function block. A parameter in function block LOCREM is
set to choose if the switch signals are coming from the
local HMI or from an external hardware switch
connected via binary inputs.
Logic rotating switch for function selection and
LHMI presentation SLGGIO
The logic rotating switch for function selection and
LHMI presentation function (SLGGIO) (or the selector
switch function block) is used to get a selector switch
functionality similar to the one provided by a hardware
selector switch. Hardware selector switches are used
extensively by utilities, in order to have different
functions operating on pre-set values. Hardware
switches are however sources for maintenance issues,
lower system reliability and an extended purchase
portfolio. The logic selector switches eliminate all these
problems.
Selector mini switch VSGGIO
The Selector mini switch VSGGIO function block is a
multipurpose function used for a variety of applications,
as a general purpose switch.
VSGGIO can be controlled from the menu or from a
symbol on the single line diagram (SLD) on the local HMI.
IEC 61850 generic communication I/O functions
DPGGIO
The IEC 61850 generic communication I/O functions
(DPGGIO) function block is used to send double
indications to other systems or equipment in the
substation. It is especially used in the interlocking and
reservation station-wide logics.
Single point generic control 8 signals SPC8GGIO
The Single point generic control 8 signals (SPC8GGIO)
function block is a collection of 8 single point
commands, designed to bring in commands from
REMOTE (SCADA) to those parts of the logic
configuration that do not need extensive command
receiving functionality (for example, SCSWI). In this way,
simple commands can be sent directly to the IED
outputs, without confirmation. Confirmation (status) of
the result of the commands is supposed to be achieved
