That would be a "surge protector". Note that many UPS (uninterruptable power supply) units include this functionality too.
See related links. This company specialized in patented lightning isolation devices to protect your electrical equipment from lightning surges.
It is a device used on power systems above 1000 volts to protect other equipment from lightning and switching surges.

The best protection is a good UPS (Uninterruptible Power Supply). That will protect you against both surges and brown outs, as well as allowing you to power down safely in case of a power outage.
Short circuits.
A surge suppressor is designed to protect electronic devices from power surges by diverting excess voltage away from the devices. It acts as a barrier between the device and the electrical outlet, absorbing or redirecting the extra voltage to prevent damage to the device.
It's true that a surge protector would protect against surges like those caused by lightning strikes but would do nothing to help with sags and brownouts. To address both high voltage (surges) and low voltage (brownouts) you would need an uninterruptible power supply (UPS). A UPS provides clean current by powering your computer from the battery while simultaneously charging the battery from the electrical supply.
A surge protector is a device that safeguards electronic devices from power surges by diverting excess voltage to the ground, preventing damage to the devices.
Surge protectors are used to protect electrical devices and appliances from voltage spikes or surges caused by fluctuations in the electrical supply. These surges can be caused by lightning strikes, power outages, or grid disturbances, and can damage or destroy electronics and other sensitive equipment in a home.
it cant protect the system against power surges
A surge protector is a device that helps protect electronic devices from power surges by diverting excess voltage away from the devices. It acts as a barrier between the devices and the electrical outlet, preventing damage from sudden spikes in voltage.
A surge protector works by diverting excess voltage from power surges away from electronic devices, preventing damage to them. It acts as a barrier between the device and the electrical outlet, absorbing the extra energy and keeping the device safe.
