Micro-blackouts, also known as micro-abortions, are brief interruptions in the power supply that usually last less than one second. These outages can be caused by a variety of factors, including distribution network problems, atmospheric influences, accidents, or rapid changes in electricity consumption.

Although micro-blackouts are brief, they can cause significant problems in sensitive electronic systems such as computers, data centers, or medical devices. Therefore, it is often necessary to use backup power supplies or power interruption protection systems to minimize potential damage or interruptions in operation.
