Surges are often caused by power interruptions and changes in electrical consumption, including the demands of other equipment that share the same power supply. When high-energy appliances are turned on and off, they can cause system surges due to fluctuating demand. They can be caused by storms or surges during use; for example, a very hot or very cold day, when suddenly everyone turns on their ovens or air conditioning. Storms can damage the power grid in other ways, such as when the wind knocks down a tree over an active power line.
There are several causes of a power surge. The main reasons are electrical overload, faulty wiring, lightning strikes, and the restoration of power after a power outage or power outage. Let's go over each of these causes in more detail. Remember to keep all valuable devices or complex appliances unplugged during severe storms and try to equip larger appliances with their own circuits or, at least, their own outlets for energy.
