TABLE OF CHARACTERISTICS
G20, G30 SIIIA TAL040F, TAL042C
Table of average values:
Alternator - 4 pole - 50 Hz - Winding no. 6.
The voltage and current values are given for no-load
operation and operation at rated load with separate field
excitation. All values are given to ± 10% (for exact
values, consult the test report) and are subject to change
without prior warning.
Three-phase: 4-pole, SHUNT excitation
Resistances at 20 °C (Ω)
Field excitation current i exc (A)
400V - 50 Hz
“i exc”: excitation current of the exciter field
Dedicated single-phase: 4-pole, SHUNT excitation
Resistances at 20 °C (Ω)
Field excitation current i exc (A)

TABLE OF CHARACTERISTICS
G40 SIIIA LSA42.3
Table of average values:
Alternator - 4 pole - 50 Hz/60 Hz - Winding no. 6 and M or
M1 connected in dedicated single-phase (400 V for the
excitation values).
The voltage and current values are given for no-load
operation and operation at rated load with separate field
excitation. All values are given to ± 10% (for exact
values, consult the test report) and are subject to change
without prior warning. For 60 Hz operation, the resistance
values are the same and the excitation current “i exc” is
approximately 5 to 10% weaker.
Three-phase: 4-pole, AREP excitation
Resistances at 20 °C (Ω)
Resistance of auxiliary windings at 20 °C (Ω)
Field excitation current i exc (A)
400V - 50 Hz
“i exc”: excitation current of the exciter field
Field excitation current i exc (A)
