Figure 75:
Connection of the SESRSYN (25) function block in a single breaker,
double busbar arrangement with internal voltage selection.
When internal voltage selection is needed, the voltage transformer circuit connections are
made according to figure
. 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
. The voltage selection parameter
CBConfig
is set to
Double bus
.

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
