In most cases it's going to be dependent on what's causing the sag; obviously, if it's caused by say a large induction motor spinning up or something like that, the sag will continue until the Istart of the motor drops to it's normal running current. IF I am remembering correctly, for most normal induction motors this is less than half a second, since the faster the motor runs, the less the stator windings look like a short. The short version: it depends primarily on the cause.
