Name Range Step Default Description
Generator nominal
voltage (Vt)
0.001…25.000kV 0.001kV 6.000kV Determines the generator's nominal voltage.
System nominal
frequency
7.000…75.000Hz 0.001Hz 50.000Hz
Determines the nominal frequency used by the
system.
VT primary 1.0…1 000 000.0V 0.1V 20 000.0V Determines the voltage in the primary of the voltage
transformer.
VT secondary 0.2…400.0V 0.1V 100.0V
Determines the voltage in the secondary of the
voltage transformer.
Phase CT primary 1.000…25 000.000A 0.001A 100.000A
Determines the phase current in the primary of the
current transformer.
Phase CT
secondary
0.200…10.000A 0.001A 5.000A
Determines the phase current in the primary of the
current transformer.
ILx polarity
0: -
1: Invert
- 0: -
Allows the user to invert the polarity of the selected
phase current (IL1, IL2, IL3).

Name Range Step Default Description
No-load
field
current
0.1…3000.00A
(DC)
0.01A (DC)
10.00A
(DC)
Displays the value of the field current with which the idling generator
voltage and frequency are nominal. This figure can be attained from
the generator manual, by measuring it, or by reading it from the
panel (the "Excitation current") when the generator has both nominal
voltage and nominal frequency.
You can calculate the per-unit values from this value.
Max.
continuous
field
current
0.10…3000.00A
(DC)
0.01A (DC) 20.00A
(DC)
Displays the maximum allowed continuous field current. This value
can be attained from the generator type plate, or from the data
pages of the generator manual.
With this value, the generator produces the nominal reactive power,
while the active power and voltage are nominal.
If the current exceeds this value, the delayed field current limiter is
activated (please refer to the chapter "Delayed field current limiter" in
this manual for more details).
Field
forcing
current
0.10…6000.00A
(DC)
0.01A (DC) 40.00A
(DC)
The maximum allowed momentary field current, which can be used
to support the power network.
If the current exceeds this value, the instantaneous field current
limiter is activated (please refer to the chapter "Instantaneous field
current limiter" in this manual for more details).
No-load
field
voltage at
warm field
winding
0.10…400.00V
(DC)
0.01V (DC) 100.00V
(DC)
Displays the voltage that is in effect over the warm field winding with
a no-load field current.
This value can be attained from the generator manual, or by
measuring it from the excitation voltage when both the voltage and
frequency are nominal.
Rated
supply
voltage to
rectifier
0.00…1000.00V
(AC)
0.01V (AC) 400.00V
(AC)
Displays the rated supply voltage to the rectifier.
Power

AC supply
1: Single-phase
AC supply
-
0:
Three-
phase
AC
supply
Selects the number of power supply phases.
