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 On or Off . The setting Off 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
• 1 1/2 circuit breaker arrangement with the breaker connected to busbar 1
• 1 1/2 circuit breaker arrangement with the breaker connected to busbar 2
• 1 1/2 circuit breaker arrangement with the breaker connected to line 1 and 2 (tie
breaker)
URatio
The URatio is defined as URatio = bus voltage / line voltage . This setting scales up the
line voltage to an equal level with the bus voltage.
PhaseShift
This setting is used to compensate the phase shift between the measured bus voltage
and line voltage when:
