When internal voltage selection is needed, the voltage transformer circuit
connections are made according to figure 36. The voltage from the busbar 1 VT is
connected to U3PBB1 and the voltage from busbar 2 is connected to U3PBB2. The
voltage from the line VT is connected to U3PLN1. The positions of the
disconnectors and VT fuses shall be connected as shown in figure 36. The voltage
selection parameter CBConfig is set to Double bus.

Setting guidelines

The setting parameters for the Synchronizing, synchrocheck and energizing check
function SESRSYN are set via the local HMI (LHMI) or PCM600.
This setting guidelines describes the settings of the SESRSYN function via the
LHMI.
Common base IED value for primary voltage ( UBase ) is set in a Global base
value function, GBASVAL, found under Main menu//Configuration/Power
system/GlobalBaseValue/GBASVAL_X/UBase. The SESRSYN function has one
setting for the bus reference voltage (GblBaseSelBus) and one setting for the line
reference voltage (GblBaseSelLine) which independently of each other can be set
to select one of the twelve GBASVAL functions used for reference of base values.
This means that the reference voltage of bus and line can be set to different values.
The settings for the SESRSYN function are found under Main menu/Settings/IED
Settings/Control/Synchronizing(25,SC/VC)/SESRSYN(25,SC/VC):X has been
divided into four different setting groups: General, Synchronizing, Synchrocheck
and Energizingcheck.
General settings
Operation: The operation mode can be set On or Off. The setting Off disables the
whole function.
GblBaseSelBus and GblBaseSelLine
These configuration settings are used for selecting one of twelve GBASVAL
functions, which then is used as base value reference voltage, for bus and line
respectively.
SelPhaseBus1 and SelPhaseBus2
Configuration parameters for selecting the measuring phase of the voltage for
busbar 1 and 2 respectively, which can be a single-phase (phase-neutral), two-
phase (phase-phase) or a positive sequence voltage.
SelPhaseLine1 and SelPhaseLine2
Configuration parameters for selecting the measuring phase of the voltage for line
1 and 2 respectively, which can be a single-phase (phase-neutral), two-phase
(phase-phase) or a positive sequence voltage.
