from busbar1 VT is connected to V3PB1 on SESRSYN1 and the voltage from busbar2 VT
is connected to V3PB1 on SESRSYN2. The voltage from the line VT is connected to
V3PL1 on both SESRSYN1 and SESRSYN2. The condition of VT fuses shall also be
connected as shown in figure 135. The voltage selection parameter CBConfig is set to No
voltage sel. for both SESRSYN1 and SESRSYN2.

Setting guidelines

The setting parameters for the Synchronizing, synchronism check and energizing check
function SESRSYN (25) are set via the local HMI (LHMI) or PCM600.
This setting guidelines describes the settings of the SESRSYN (25) function via the
LHMI.
Common base IED value for primary voltage (VBase) is set in a Global base value
function, GBASVAL, found under Main menu/Configuration/Power system/Global
base values/X:GBASVAL/VBase. GBASVAL has six instances which can be set
independently of each other. The SESRSYN (25) 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 six
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 (25)
function found under Main menu/Settings/Control/SESRCYN(25,SYNC)/
X:SESRSYN has been divided into four different setting groups: General,
Synchronizing, Synchrocheck and Energizing check.
General settings
Operation: The operation mode can be set Enabled or Disabled. The setting Disabled
disables the whole function.
GblBaseSelBus and GblBaseSelLine
These configuration settings are used for selecting one of six GBASVAL functions; the
base voltage UBase of the set Global Base Value group is used as base value of the voltage,
for bus and line respectively.
SelPhaseBus1 and SelPhaseBus2
Configuration parameters for selection of measuring phase of the voltage for the busbar 1
and 2 respectively, which can be a single-phase (phase-neutral) or two-phase (phase-
phase) voltage or positive sequence.
SelPhaseLine1 and SelPhaseLine2
