Brownout

A brownout refers to a temporary drop in voltage in an electrical power supply system, often resulting in a dimming of lights and reduction in the performance of electrical devices. Unlike a blackout, which is a total loss of power, a brownout is characterized by reduced voltage levels, typically lasting for a few minutes to several hours. This reduction in power can cause lights to flicker and electronic devices to underperform or malfunction, potentially leading to damage if the devices are not adequately protected.

Brownouts can occur for several reasons, including high demand on the power grid, equipment failures, or intentional actions by utility companies to prevent a total blackout. When the demand for electricity exceeds supply, utility companies may reduce voltage levels to maintain stability in the power grid, thereby preventing a complete shutdown. While brownouts are less severe than blackouts, they can still pose challenges for consumers and businesses, especially those that rely heavily on sensitive electronic equipment. To mitigate the impact of brownouts, it is advisable to use uninterruptible power supply (UPS) systems and voltage regulators to protect critical devices.
