Power Surge Protection: How it Works

From here


A power surge is an increase in voltage flowing through your electrical units that rise above the standard voltage levels (120 Volts). These surges can be caused by lightning, high-powered electrical devices (elevators, air conditioners, refrigerators, etc), faulty wiring or even problems with your utility company’s equipment. Inevitably, these are all occurrences that we cannot prevent ourselves, so how can you protect your home and equipment from these damaging power surges?

Surge Protector

A simple solution is plugging in your electronics into a surge protector. A surge protector is a device used to protect your electronics from damaging power surges. However, many people use this tool for a much more obvious function, to plug in multiple components into one outlet, not knowing its protective capabilities. You most likely use at least one surge protector in your home already. But how does it work? How do you know that you are providing the top quality protection for your important devices?

How it Works

As you know, your surge protector pulls electrical currents from one outlet and passes them through all the electrical devices plugged into the surge protector. This aside, the more important feature of this device is its metal oxide varistor (MOV) component, which diverts extra voltage and preventing it from damaging your electronics. This MOV acts in different ways depending on the voltage flow to provide your devices consistent access to adequate levels of power. If the MOV indicates high levels of voltage, it will reduce the resistance and if the voltages are low it will create a higher resistance. However, it is important to be aware that these MOV’s can also burn out. By investing in a power surge with an indicator light you will always be able to determine whether or not it’s functioning appropriately.
