What is a Power Surge?

What is a power surge? Perhaps you’ve heard this term and wondered exactly what it is and why it’s so important to prepare for them.  A power surge occurs when something boosts the electrical charge in the power lines. When this happens, there’s an increase in the electrical potential energy, which can increase the current flowing to your wall outlet.

Power surges can be caused by any number of things including lightning, though lightning is not a very common cause.  High-powered electrical devices like elevators, air conditioners, and refrigerators are a common cause of power surges.  Turning these devices on and off creates sudden, brief demands for power.  This can upset the steady voltage flow in the electrical system, causing a power surge.  Faulty wiring, downed power lines, or other problems with the utility company’s equipment can also cause surges.

How can power surges be harmful?  Many modern electronic devices like DVD players, computers, and microwaves contain components that are sensitive to current increases.  Computers and any other home appliances that contain microprocessors are particularly sensitive to power surges.  These devices depend on a steady flow of power at the correct voltage.  Power surges can shorten the life of computers, and potentially wipe out saved data or destroy the whole system.

In order to protect your appliances from these unavoidable power surges, it is a good idea to use surge protectors.  Surge protectors help maintain the constant flow of power that appliances like computers and entertainment systems rely on.  Surge protectors can help minimize or eliminate the damage from small fluctuations in voltage flow, which can extend the life of your appliances.  It can be a hassle to use small surge protector power strips for all of your appliances, especially if you own many electronics.  To be sure that your whole home is protected from power surges, whole home surge protection should be used.

  1. I have a SteadyPower that was installed in January and still experiencing surges…such as lights dimming, FreshAir purifier
    power up & down, microwave power up & down all with normal use.
    Could the SteadyPower not be installed correctly?

    Thank you

  2. Steady Power has truly been an asset to our property! We immediately noticed that our appliances are quieter and are running smoother! We love the peace of mind by just knowing we are extending their life and not only saving money monthly, but long term!

  3. This is one of the best products we offer. BY using a power factor meter (get them on Amazon) you can actually tell a customer how much energy they are losing and how efficient their homes are. Couple this with the power surge protection feature of the Steady Power and you have a great tool for saving energy and protecting your home.

  4. Thank you for the post. It was great! I have the steady power and after experiencing a mico-burst in Arizona it saved all my appliance. A lot of my neighbors experienced a lot of electrical problems due to the power surges.
