What is a surge protector?

Many people are not aware of what a surge protector is and they tend to miss believe that this device is a simple multi-plus extension cord with a fancy name. In reality, the surge protector is more than a simple apparatus used to turn the single power outlet into 6 or even more. It plays a huge role in protecting the entire electronic device collection that you own in your house. So, you need to pay attention to this surge protector and learn a few useful tips that could come handy in the near future.

Firstly, before finding out how this surge protector actually works, you need to understand the meaning of an electrical surge. The flow of electricity moves from high potential energy areas to low potential energy places. Basically, it’s a move that goes from one point to another, in the same wire.



We use the voltage to measure this electric potential energy, more precise, the difference from one area to another. When the voltage remains high for at 3 nanoseconds, we’ve got a surge. If the difference from one potential energy to another is too high, the electricity surges through. Thus, the wire heats up and it can burn.

Thanks to the surge protector, the excess voltage is detected and the extra electricity is sent to the grounding wire. This is the reason why every surge protector you’ll find on the market comes with a grounding pin which is the third projection located on the plug. Moreover, these devices need to be plugged into a grounded outlet for excellent results.


There are numerous reasons why you should start using a surge protector immediately. The only problem is that you need to know which devices should be connected to it because not every electronic item from your house is exposed to these situations of high voltage.

For instance, your desk lamp or your mini standing fan don’t need a surge protector but expensive pieces such as laptops, televisions, stereo systems, that are outfitted with intricate microprocessors, need this type of protection.

The selection is quite easy to make. Just think like this: if there was the possibility of an electrical surge to destroy your devices connected to your power outlets, which one would cost more to repair or to replace. Those are the ones that need to be connected to a surge protector. It’s best to take all precautions than to be sorry afterward.

Plus, surge protectors come in handy if you want to prevent cable clutter and to organize your electronic devices properly. Since all cables end up being transferred to the same destination, it’s easier to have control over them. With a simple switch, you can unplug more than one device.
