Rated Voltage
Parameter 16
Gen.voltage
V set 000V
Generator voltage set point [1] 50 to 125 V; [4] 50 to 530 V
L This value corresponds to the rated voltage on the secondary side of the
PTs, which are directly connected to the control.
The generator voltage set point is configured here. This is the reference voltage that
the generator will control at when operating in an isolated and/or no-load applica-
tions. The voltage controller enable set point (Parameter 55) refers to the value con-
fig
ured in this parameter.
Parameter 17
Rated voltage in
system 000V
Rated system voltage [1] 50 to 125 V; [4] 50 to 480 V
The system rated voltage (V
L-L
) is defined in this parameter.
The following parameters use the value configured here as a protection and control
reference point:
- Generator voltage monitoring
- Mains voltage monitoring
- Voltage controller dead band
- Maximum voltage differential (dV max) for synchronization
- Maximum voltage differential (dV max) for a GCB dead bus closure

Voltage measuring/voltage monitoring Ph-neut./Ph-Ph
The control can monitor either the phase-neutral voltages (four-wire system) or the
phase-phase voltages (three-wire system). Generally, low-voltage systems are con-
figured to monitor the phase-neutral voltages, while medium- and high-voltage sys-
tems are configured to monitor the phase-phase voltages only. The monitoring of the
phase-phase voltages is recommended to avoid a phase-earth fault in a compensated
or isolated mains resulting in the voltage protection tripping.
Ph-neut/Ph-neut System voltage measurement is performed phase-neutral (WYE
connected system). The phase voltages and the neutral must be
connected for proper calculation. This requires that the neutral
terminal (terminal 0) be connected to the ground reference. The
voltage measurement and protection functions are performed in
accordance with WYE connected systems. The phase-phase and
phase-neutral voltages are displayed.
Ph-neut/Ph-Ph System voltage measurement is performed phase-neutral (WYE
connected system). The phase voltages and the neutral must be
connected for proper calculation. This requires that the neutral
terminal (terminal 0) be connected to the ground reference. The
phase-phase and phase-neutral voltages are displayed. The vol-
tage protection is performed phase-phase only.
Ph-Ph/Ph-Ph System voltage measurement is performed phase-phase (Delta
connected system). Phase voltages must be connected for proper
calculation. This does not require the neutral terminal (terminal 0)
be connected to the ground reference. The voltage measurement
and protection functions performed in accordance with Delta
connected systems. Only the phase-phase voltages are displayed.
Note:
Ph-neut = Four-wire system (3ph 4w)/Wye
Ph-Ph = Three-wire system (3ph 3w)/Delta
