( 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
Configuration parameters for selection of measuring phase of the voltage for line 1 and 2
respectively, which can be a single-phase (phase-neutral) or two-phase (phase-phase)
voltage or positive sequence.
CBConfig
This configuration setting is used to define type of voltage selection. Type of voltage
selection can be selected as:
• no voltage selection
• single circuit breaker with double bus
• breaker-and-a-half arrangement with the breaker connected to busbar 1
• breaker-and-a-half arrangement with the breaker connected to busbar 2
• breaker-and-a-half arrangement with the breaker connected to line 1 and 2 (tie
breaker)
VRatio
The VRatio is defined as VRatio = bus voltage / line voltage . This setting scales up the line
voltage to an equal level with the bus voltage.
