Power Sag Definition: Power sags involve voltages 80 to 85 percent below normal for short periods of time (one or more cycles). Possible causes are heavy equipment being turned on, large electrical motors being started, and the switching of power mains (internal or utility). A power sag can have effects similar to those of a power surge, such as memory loss, data errors, flickering lights and equipment shutoff.
