Containing Power: An Introduction to Power Surges

No one ever wants to experience a power surge. Aside from the usual dangers of imbalanced electrical currents, your appliances and electrical gadgets can also get damaged. This is apparent during thunderstorms when your TV and laptop are plugged in. Once the dust settles, you may find that they no longer work, getting fried due to the frequent surge!

Indeed, power surges are not something an average homeowner would like to encounter. That’s why as much as possible, preventive measures are taken to prepare for them! Thankfully, there is a very effective countermeasure against power surges, giving you and your home appliances a fighting chance once a second thunderstorm arrives.

What Is a Power Surge? What Causes It?

The way that your home appliances work is that there is a constant amount of current surging through them. This isn’t limited to one device alone, as the same thing can be said about your flat-screen TV, your computer, your washing machine, and your phone charger, among others.

Now, during a storm, a lightning strike may disrupt that constant flow of electricity. The currents may either stop or be overloaded with vast amounts of electricity, thus causing damages to your valuables.

“on’t My Appliances work with Electricity? Why Would a Surge Damage Them?”

All of your appliances and gadgets at home have a certain amount of allowable voltage in them. Yes, they need electricity to work—but as with everything, too much can lead to overloading, leading to negative consequences. It is the same thing with balloons, where you should not put too much air in them; otherwise, they may burst.

“Do Thunderstorms Cause Power Surges All the Time?”

No, thunderstorms aren’t the only cause of a power surge. There are times when your local power plant may experience some error in their lines, requiring maintenance over time. These sudden repairs would cause fluctuations within your power, resulting in a power surge as well.

To prevent such things from affecting you, be alert at all times, check your local news stations for tidbits about upcoming repairs, and prepare a couple of flashlights and rechargeable batteries just in case you’ll need to switch off your mainline.

“How Could I Protect My Home from a Power Surge?”

The good news is, you can avoid frying your devices with the help of a surge protector.

A surge protector is designed to “sense” the incoming currents, predicting the exact moment when a sudden increase in voltage would strike your devices. The protector would then re-route the dangerous amounts of voltage away from your valuables, saving you thousands of dollars. If you still do not have any surge protectors at home, call up your local electricians to install them.


Power surges are hazardous, especially if you do not have any surge protectors at home. They can damage your devices, your appliances, and even your property when left unchecked. Regularly have your wires maintained, call up for electrical repairs whenever needed, and do not hesitate to switch off your breakers once the lights start flickering. Protect your home from the dangers of electrical damage by being cautious and wise.
