Brownout failure of electrical service refers to a power outage that is less severe than a blackout but still results in a drop in voltage levels. During a brownout, electrical appliances and devices may experience intermittent power interruptions or reduced power output, leading to flickering lights and the inability to operate some equipment. Synonyms for brownout include partial blackout, voltage dip, power dip, power flicker, and low voltage condition. Regardless of the term used, a brownout can cause inconvenience and disruption, particularly in critical facilities such as hospitals and data centers, and may even damage sensitive equipment if the voltage fluctuation is severe or prolonged.
