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 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 Enabled or Disabled . The setting Disabled 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.
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,
PhaseShift
This setting is used to compensate the phase shift between the measured bus voltage and line
voltage when:
• different phase-neutral voltages are selected (for example UL1 for bus and UL2 for line);
• one available voltage is phase-phase and the other one is phase-neutral (for example UL1L2
for bus and UL1 for line).
The set value is added to the measured line phase angle. The bus voltage is reference voltage.
