What is the purpose of a surge protector in electrical systems?

The purpose of a surge protector in electrical systems is to protect against voltage spikes. Voltage spikes can occur due to various reasons, such as lightning strikes, power outages, or the cycling of heavy electrical equipment. When these spikes occur, they can lead to excessive voltage levels that threaten the integrity of electrical devices and systems.

Surge protectors work by diverting excess voltage away from sensitive equipment, ensuring that the voltage levels remain within safe operational limits. This is essential for preventing damage to devices such as computers, appliances, and other electronic equipment that may be adversely affected by sudden increases in voltage. By acting as a buffer, surge protectors help to prolong the lifespan of equipment and prevent costly repairs or replacements.

In contrast, preventing voltage drops, enhancing power quality, and stabilizing current flow involve different aspects of electrical performance and are not the primary function of a surge protector.
