The arrival of summer can mean several welcome events: a return to outdoors living, an opportunity for vacation, and more time with the family. One of the issues people may not associate with summer are the power surges that often occur due to the tremendous demand for energy, especially to cool homes. A power surge is a brief spike in electrical power. While on the surface it may not seem like much to be concerned about, power surges can cause serious damage by burning up electrical circuits inside appliances. They can also damage electrical outlets, light switches, light bulbs, air conditioner components, and even garage door openers.
You can protect your valuable electrical appliances from the damaging effects of power surges. The most cost effective way is by purchasing surge protection strips. You can plug in your television, DVD player, and stereo into the strip and it should provide adequate protection against most surges. It’s a good idea to pick up a surge protection strip for the kitchen counter so that you can protect small electrics like the toaster, blender, food processor etc. You can also find surge protectors that fit into electrical outlets that will protect your phone and answering machine. You can buy most types of surge protectors in any local hardware store.
When it comes to your PC, however, you will have to be a bit more selective about protection, because of the delicacy of its internal components. Back-up power packs that are specifically designed to protect your hardware can be found in stores that sell computer accessories as well as in many electronics chain stores. They can be somewhat expensive, but are certainly less expensive than replacing your entire system.
Before you purchase any surge protector, there are certain features you need to look for. The first feature to look for is a surge protector that is labeled with the Underwriters Laboratories (UL) logo. The UL logo tells you that the unit has been tested to determine if it meets certain standards. Any product that is UL tested will be labeled as a “transient voltage surge protector,” which means that it meets or exceeds the minimum standards required to be an effective deterrent against power surges.
A surge protector’s performance is rated in three ways. The first is clamping voltage, which is the level of voltage surge that has to occur before the surge protector kicks in and diverts excess voltage from the item being protected. You want to find a surge protector that has a low voltage number so that it takes less of a surge to activate it. Look for a protector with a clamping voltage of less than 400 volts.
The second way to rate a surge protector’s performance is response time: the amount of time it takes for the surge protector to respond to the surge. You should look for a unit with a response time of one nanosecond or less.
Just like any other appliance in your home, your surge protector will eventually wear out. The third performance-rating factor is energy absorption, or how much energy the unit will absorb before it fails. For the longest lasting performance, look for a unit rated between 300 and 600 joules. Remember, the higher the number, the longer the life of the surge protector.
