Surge Protector

Definition

A surge protector is a device that is designed to protect electronic equipment from voltage spikes or surges in the electrical power supply. It acts as a safeguard against sudden, potentially damaging increases in voltage that can occur due to various reasons, such as lightning strikes, power outages, or issues with the electrical grid.

5 Must Know Facts For Your Next Test

1. Surge protectors are essential for protecting household electronics and appliances from power surges, which can occur due to lightning strikes, power outages, or other electrical disturbances.
2. The Joule rating of a surge protector indicates the amount of energy it can absorb before it becomes ineffective, with higher Joule ratings providing better protection.
3. Clamping voltage is the maximum voltage that a surge protector will allow to pass through to the connected devices, ensuring that the voltage remains within a safe range.
4. Surge protectors should be replaced periodically, as their protective components can degrade over time, reducing their effectiveness.
5. Proper grounding is essential for surge protectors to function effectively, as it provides a path for excess voltage to be safely dissipated.
