Surge protection is a mechanism designed to protect electronic devices and appliances from voltage spikes or surges. These surges can occur due to lightning strikes, power outages, or other electrical disturbances in the power grid. A surge protector works by diverting excess voltage away from the connected devices and directing it towards the grounding wire or path. This helps prevent damage to the devices and appliances and can prolong their lifespan. Surge protectors come in various forms, including power strips, wall-mounted units, and whole-house surge protection systems.
