Generator
rated voltage
2
50 to 650000 V
480 V
This voltage is always entered as a “Phase - phase” value. The
rated generator potential transformer primary voltage is used as a
reference figure for all generator voltage related functions, which
use a percentage value, like operating range limits, voltage trim
and voltage monitoring.
NOTE: This value refers to the rated voltage of the generator (ge-
nerator voltage on data plate) and is the voltage measured on the
potential transformer primary.

L1 L2 L3: All three phases are monitored. Measurement, display
and protection are adjusted according to the rules for 3-phase
measurement.
Phase L {1/2/3}: Only one phase is monitored. Measurement,
display and protection are adjusted according to the rules for sin-
gle-phase measurement. Monitoring refers to the selected phase.
NOTE: Please refer to the comments on measuring principles in
the installation chapter. This parameter is only effective if Genera-
tor voltage measuring (parameter 1851) is configured to
“3Ph 4W”, “3Ph 3W” or “3Ph 4W OD”.

3Ph 4W: Wye connected voltages
Generator voltage is connected using all 3 phases and a neutral.
This measurement can be directly connected or through potential
transformers (PTs). Voltage monitoring is configured in the
“VAR/PF Menu 4”, parameter 1770. This setting determines if the
DSLC-2 uses “Phase - phase” or “Phase - neutral” voltage for pro-
tection.
3Ph 3W: Delta connected voltages
Generator voltage is connected using all 3 phases. This mea-
surement can be directly connected or through potential transfor-
mers (PTs).
This configuration is used when:
• The generator is connected to the load using 3-phase
and neutral
• The generator voltage is connected to the DSLC-2
using 3-wire, “Phase - phase”
• The L2 phase is not grounded on the input of the
DSLC-2
And when:
• The generator is connected to the load using 3 phases
and no neutral
• The generator voltage is connected to the DSLC-2
using 3 wire, “Phase - phase”
• The L2 phase can be grounded or left ungrounded
3Ph 4W OD: Delta connected voltages
Generator voltage is connected using all 3 phases without a neu-
tral connection. This measurement can be directly connected or
through potential transformers (PTs).
This configuration is used when:
• The generator is connected to the load using 3-phase
and neutral
• The generator voltage is connected to the DSLC-2 us-
ing 3 wire, “Phase - phase”
• The L2 phase is grounded on the input of the DSLC-2

the installation chapter (“Voltage Measuring: Generator” on page
