What is the purpose of surge protectors in electrical systems?

The purpose of surge protectors in electrical systems is to protect against voltage spikes and surges. When there are sudden increases in voltage, often caused by lightning strikes, power outages, or other disturbances in the power grid, surge protectors divert or limit the excess voltage to prevent it from damaging electrical devices and equipment connected to the system.

Surge protectors work by redirecting the surge energy away from sensitive devices, safeguarding them from potential failure. This protection is crucial for maintaining the longevity and functionality of electronic equipment, particularly in environments where such voltage spikes are more commonplace. Thus, their primary role is centered around preserving the integrity of electrical components by controlling sudden increases in voltage, rather than enhancing efficiency, increasing capacity, or regulating current.
