What is the role of surge protectors in electrical systems?

Surge protectors play a critical role in electrical systems by preventing damage from voltage spikes, which can occur due to various reasons such as lightning strikes, power surges, or switching operations in the power grid. When a surge occurs, it can result in excessive voltage levels that can harm electrical equipment or lead to catastrophic failures. Surge protectors are designed to divert this excess voltage away from sensitive equipment, thereby protecting components like computers, appliances, and communication systems from potential damage.

The effectiveness of a surge protector is typically based on its ability to limit the voltage supplied to the connected devices, ensuring that they operate within safe levels. This protection mechanism helps to maintain the longevity and reliability of electrical equipment by safeguarding them from unexpected voltage spikes. Thus, surge protectors are an essential component in maintaining the integrity and safety of electrical systems.
