WebBlackout/brownout A blackout is a total loss of electrical power. A blackout is usually defined as a drop in line voltage below 80 volts (V) (the normal voltage is 120V), since most electrical equipment will not operate below these levels. A blackout may be due to a planned interruption, such as limiting of loads during power shortages by rotating power shutoffs … WebMar 4, 2024 · A sag is a slight decrease in voltage, while a brownout is a bigger decrease in voltage.

WebAug 2, 2024 · Despite the confusion between brownout vs blackout, these terms are different. Brownouts are most similar to voltage sags, where there is usually a “sag” in voltage levels before an eventual return to normal levels. During brownouts, devices can still get power, albeit at a reduced level, and are more likely to malfunction than fail.
