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 twelve GBASVAL
functions, which then is used as base value reference voltage, for bus and line
respectively
.
SelPhaseBus
Configuration parameters for selecting the measuring phase of the voltage for
busbar, which can be a single-phase (phase-neutral) or a positive sequence voltage.
SelPhaseLine
Configuration parameters for selecting the measuring phase of the voltage for line,
which can be a single-phase (phase-neutral) or a positive sequence voltage.
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 positive sequence and the other one is phase-neutral
(for example Pos. Seq. for bus and UL2 for line).
The set value is added to the measured line phase angle. The bus voltage is
reference voltage.
Synchronizing settings
OperationSynch
The setting Off disables the Synchronizing function. With the setting On, the
function is in the service mode and the output signal depends on the input
conditions.
UHighBusSynch and UHighLineSynch
The voltage level settings shall be chosen in relation to the bus/line network
voltage. The threshold voltages UHighBusSynch and UHighLineSynch have to be
set lower than the value where the network is expected to be synchronized. A
typical value is 80% of the rated voltage.
