5.2.2.3. Case 6: Three Phase Voltage Sag<br />
In this case, three phase balanced fault occurs. A, B and C phase source<br />
voltages decrease to 70% from its nominal value during the period of 0.3-0.4 s. In all<br />
phases, phase jump occurs between source-side and load-side voltages. Figure<br />
5.20 shows the simulation results source-side voltages and injected voltages under<br />
three-phase to ground fault. The load voltage is maintained at the desired 1 p.u. as<br />
shown in Figure 5.20.<br />
