Sudden Power Drop

A.

The electrical event that shows a sudden drop of power source that can cause a wide variety of problems on a PC or a network is called a power sag or voltage dip.

A power sag occurs when the voltage of an electrical power supply drops below the normal level for a short period of time, usually less than one minute. This sudden drop in voltage can cause a variety of problems in electronic devices, including computers and network equipment.

During a power sag, the voltage drop can cause the power supply to shut down or the device to malfunction, resulting in data loss, system crashes, or even hardware damage. The duration of a power sag can vary, and the severity of the voltage drop can depend on the cause of the event.

Power sags can be caused by a variety of factors, such as lightning strikes, power outages, or heavy electrical loads. They can also be caused by the cycling of large electrical loads on the same power line, such as air conditioners or elevators.

To protect electronic devices from power sags, it is important to use surge protectors or uninterruptible power supplies (UPS) that can filter out the voltage fluctuations and provide a stable power source to the device. UPSs are especially useful for critical systems that cannot tolerate any power interruptions or data loss, such as servers or medical equipment.
