Depending on the duration of instantaneous power interruptions and the amount of load inertia,
a low voltage trip may occur even during a kinetic energy buffering operation. Motors may
vibrate during kinetic energy buffering operation for some loads, except for variable torque loads
(for example, fan or pump loads).
