Please explain in detail. You can use a manual switch and then use two constant block(rated value and dipped value) for the phase magnitude inputs. Near RUN button there is a backward arrow. You can pause the simulation when it reaches some time (say 1 second) and click on manual switch to new value(dip) and repause the simulation. Or you can use THREE PHASE PROGRAMMABLE GENERATOR directly and select time variation of amplitude.
