What is the primary function of a surge protector?

The primary function of a surge protector is to protect electrical devices from voltage spikes, which can occur due to various reasons such as lightning strikes, power outages, or sudden changes in electrical demand. When a surge or spike in electricity occurs, the surge protector works by diverting the excess voltage away from connected devices, thereby preventing damage. This function is crucial for safeguarding sensitive electronic equipment, such as computers, televisions, and home appliances, which can be adversely affected by such fluctuations in voltage. By effectively managing and controlling unexpected increases in voltage, surge protectors ensure the longevity and reliability of electrical devices in both residential and commercial settings.
