What is a Power Surge and Why You Need a Surge Protector?

Jan 28, 2023 | Electrical Tips

Power surges are unexpected rises in voltage. They are more common than a lot of people know. Power surges can damage electronic devices and can lead to failures.

To help prevent damage to your appliances and electronics, you should have a surge protector installed. A surge protector will reroute extra electricity if a power surge occurs.

What is a Surge Protector?

A Surge protector is a device that protects electronic devices from power surges. It is designed to stop any excess voltage from reaching your electronics. The sudden increase of excess voltage during power surges can damage anything plugged into the electric system.

What is a Power Surge?

A power surge is a sudden spike of voltage. Power surges can happen out of the blue. They are not typically dangerous, but they can damage your electronics and outlets.

The strength of a power surge can vary depending on the reason for the fluctuation of voltage. When you have a surge protector installed, you are being proactive and preventing damage before it has a chance to occur.

Causes for Power Surges

Electrical Transformer Failure

Transformers can fail for many reasons. When they do fail, they can send out a sudden surge of power.

Lightning Strikes

Lightning is dangerous. It can strike anything and cause extensive damage and even death. If lightning strikes your home, an electric line, a transformer, or anywhere nearby, the sudden spike of power can cause a power surge.

The best way to prevent damage from an electrical storm is to have a surge protector installed. It is also recommended that you unplug any electrical devices that are not vital.

Power Outages

If you experience a power outage, unplug and turn off everything you can, including the lights. When the electricity comes back on, there is often a power surge. This surge can damage everything plugged in.

Causes of Power Surges

Electrical Overloading

The circuits in your home are able to carry and distribute a certain load. If too many devices are plugged into one circuit, electrical overloading can cause a power surge. It can also blow fuses and possibly cause a fire.

Faulty Wiring

Damaged wiring can be dangerous. Wires can be damaged even if they are in the walls. Pests can chew on the wires, causing permanent damage. These damaged wires will not provide a proper flow of electricity.

This improper flow can cause a surge and even fires. If you know of any damaged wires in your home, you need to call a level 2 electrician and have them replaced right away.

Preventing Power Surges

Power surges can be unpredictable. However, there are ways you can help prevent them.

To prevent power surges:

  • Do not overload your circuits.
  • During a storm, turn off the lights and unplug electrical devices.
  • Have a whole home surge protector installed.
  • Use surge protector power boards.
  • Replace any faulty wiring.
  • Have an Electrician perform an inspection.
  • Replace all non-energy efficient appliances.
