What are the precossionary even have a brown-out?

A brown-out is a temporary reduction in voltage in an electrical power supply, usually implemented to prevent a complete blackout during periods of high demand. Precautionary measures that may lead to a brown-out include load shedding, where utilities intentionally cut power to certain areas to balance supply and demand. Other factors can include equipment failures, maintenance issues, or extreme weather conditions that strain the power grid. These measures help maintain overall grid stability and prevent more severe outages.
