Figure 47: Connection of the SESRSYN (25) function block in a single breaker, double busbar
When internal voltage selection is needed, the voltage transformer circuit connections are made
according to figure 47. The voltage from busbar1 VT is connected to V3PB1 and the voltage from
busbar2 VT is connected to V3PB2. The voltage from the line VT is connected to V3PL1. The
positions of the disconnectors and VT fuses shall be connected as shown in figure 47. The voltage

10.1.4 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 (
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 (
setting for the line reference voltage (
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.
