Voltage change simulation
In this simulation, the 50 Hz 100 V power source repeats the voltage change three times at
10-second intervals, while the voltage drops to 70 % and then linearly recovers in 0.5 seconds
during one cycle as shown in Figure 4–13. For this case, set so that the total of Normal 1 and Normal
2 Step Times becomes 10 seconds and set the repeat count to 3. Set the Trans 1 Step Time to zero
(Table 4-7).
