What is the function of surge protectors in electrical systems?

Surge protectors play a crucial role in electrical systems by safeguarding electronic devices from damage caused by voltage spikes and transient surges. These surges can occur due to various factors, including lightning strikes, utility switching, or sudden changes in electrical load. When such a spike occurs, the surge protector diverts excess voltage away from the connected devices, preventing potential damage that could result in malfunction or complete failure.

This function is essential for protecting sensitive electronics, such as computers, televisions, and other equipment, that may not be able to tolerate sudden increases in electrical voltage. By effectively absorbing and redirecting excess voltage, surge protectors help extend the lifespan of devices and ensure their proper functioning, making them a critical component in both residential and commercial electrical systems.
