Can Power Surges Hurt Our Electronics And Air Conditioning System?
Posted by Jody Raines on Sun, Aug 28, 2011 @ 02:22 PM

Most homes use 120-volt, 60 Hz, single phase, alternating current to provide electricity for their home.
Voltage is delivered by alternating current; where the voltage cycles in an alternating rhythm from 0 to 169 volts. This aternating current is compatible with most appliances and electronics.
During a power surge, the voltage exceeds the peak voltage of 169 volts.
Brownouts, or spikes are harmful. An sudden surge of electricity voltage can cause an arc of electrical current. This arc damages the delicate electronic circuits.
Power surges can also be small - and these small surges also take a toll on appliances. Over time, these smaller surges can ruin your appliances and electronics.
Power surges can happen and be undetected. They may originate from the utility company during power grid switching or through events like lightening during a storm Even appliances like air conditioners or otehr heavy electrical draws may cause mini surges within your home.
To protect your electonics, you can use Surge Protection Devices (SPDs) and be sure your home is grounded. You may have plug in strips that you think have built-in surge protectors, but if they are not rated as surge protection devices, they may not protect your electronics.
- Surge protectors should list their UL Approval. This is a national benchmark.
- Look for surge protectors with an indicator light that indicates it needs to be replaced.
- Be aware of the manufacturer's warranty. Does the warrany cover the device only, or does it also cover any damaged equipment?
The best way to protect electronics and equipment from lightening during a storm is to unplug it. Power surge protection should be part of your arsenal to protect your home and devices and assure their longevity. Check with a licensed electrician to evaluate your situation and suggest ways to protect your home.
