Three Voltage Source and Two Current Source Connections
Figure 7.4 and Figure 7.5 show connections to use when three voltage sources and two current
sources are available. Phase-to-phase, phase-ground, and two-phase-ground faults may be
simulated using the connections shown in Figure 7.4. Three-phase faults may be simulated using
the connections shown in Figure 7.5.
