9.1.4 SIGNAL SOURCES
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 “GEN” source uses the phase VT inputs and the CT input wired to the gen-
erator 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 “GEN” source.
