What is the purpose of a surge protector in an electrical system?

A surge protector is primarily designed to protect electrical equipment from voltage spikes or surges that can occur due to various reasons, such as lightning strikes or power fluctuations. When these unexpected increases in voltage happen, they can potentially damage or destroy sensitive electronic devices and appliances connected to the electrical system. The surge protector acts as a buffer by absorbing the excess voltage, allowing only the normal electrical flow to pass through to the connected devices.

Surge protectors work by diverting or limiting the surge current and preventing it from reaching the connected equipment. This functionality is essential in safeguarding investments in electronics and maintaining the reliability of an electrical system.

The other aspects, like enhancing energy efficiency, reducing electromagnetic interference, and improving signal quality, focus on different concerns in electrical and electronic systems but do not address the critical protective role that surge protectors play against voltage spikes.
