What Is a Power Surge? What Causes Them?
A power surge is a burst or overload of electrical charge traveling down the power line.
It can occur at any point in the line and most often does not begin in your home.
A lightning strike is probably the first thing people think of with power surges, but they actually aren’t the most common cause of them.
However, they tend to cause the most damage due to the intensity of the power surge they trigger.
Power surges caused by lightning can be too powerful for even a surge protector, so you shouldn’t rely on one to safeguard your computer and other electronics during a lightning storm.
Large Appliances and Machinery
Many times, power surges are caused by the system needing to run a major appliance or piece of machinery such as an elevator.
This is why condominiums and apartment buildings may suffer from power surges more often than a home. Refrigerators, air conditioners, laundry machines, and other items that take large amounts of electricity to run can cause a surge.
Old wiring that is not maintained or upgraded to handle the demand of your electrical needs can also cause power surges.
Damaged outlets or overloaded electrical circuits, frayed wiring, and animal or rodent nibbling on the wires can all lead to surges.
Power Line and Utility Company Equipment Issues
Faulty or damaged equipment such as transformers, power lines, power generators, switches, and connection issues or damage can all lead to power surges.
