What is the primary purpose of surge protectors in electrical systems?

The primary purpose of surge protectors in electrical systems is to protect electrical devices from voltage spikes. Voltage spikes can occur due to various reasons, including lightning strikes, power outages, and electrical overloads. These spikes can exceed the normal operating voltage and potentially damage connected devices, which can be costly to repair or replace.

Surge protectors work by diverting excess voltage away from sensitive equipment, allowing only the normal electrical flow to reach devices. This is crucial in safeguarding electronics like computers, televisions, and home appliances, which can be particularly vulnerable to these sudden increases in voltage. By preventing damage caused by surges, surge protectors extend the life of the equipment and maintain the integrity of the electrical system.

Other options like enhancing electrical flow or converting AC to DC do not align with the function of surge protectors. Similarly, stabilizing voltage levels is not the primary role of these devices; rather, they are designed chiefly for protecting against transient spikes in voltage. Thus, the focus of a surge protector is specifically on protection from voltage fluctuations, making it vital for the reliability and longevity of electrical devices in various systems.
