Rated Voltage Low Line Scale Factor
The rated voltage low line scale factor setting Z preserves the system gains when a machine is changed
from high line (where the windings are typically in series) to low line (where the windings are typically in
parallel) configuration. When the windings are in series, typically a given change in voltage regulator bias
will result in twice the change in output voltage as the same change in bias on a low line configuration.
Correct use of the rated voltage setting and the rated voltage low line scale factor setting on a
reconfigurable machine, is to set the rated voltage to the high line voltage of the machine and set the
scale factor to 0.5 to adjust the rated voltage in the voltage trim calculation when the low line override is
active.
