A "Power Surge" is a sudden increase in electrical voltage that can occur in power lines. This spike can happen due to various reasons, such as lightning strikes, equipment malfunctions, or the sudden activation of large electrical devices. Power surges can damage electrical appliances and systems, leading to costly repairs or replacements. To protect against power surges, many people use surge protectors, which are devices designed to absorb excess voltage. These protectors can be found in power strips or as standalone units. Regular maintenance of electrical systems can also help minimize the risk of damage from power surges.
