9.1 SETTING EXAMPLE
For the example system, the voltage settings are calculated as follows:
Enter the following values through EnerVista UR Setup (or alternately, through the front panel

Frequency tracking should always be enabled for generator applications. Make the following power system parameters
changes via EnerVista UR Setup or through the
menu:
Two sources are required for this application example. The "LINE" source uses the phase and auxiliary VT inputs and the
CT input wired to the generator output CT. The "NEUTRL" source uses the phase VT inputs and the CT input wired to the
generator neutral CT. Including the phase VT inputs for both sources allows the user to choose the location of elements that
use both voltage and current. Elements using the auxiliary VT input are assigned to the "NEUTRL" source.
