What causes power surges?

Thunderstorms and lightning are the most dramatic and destructive causes of power surges.  However, cycling on and off of home appliances, and trees, birds or squirrels touching a power line can also create power surges.

Can these cause damage?

Yes.  Today's computerized appliances and sensitive electronics can be damaged or destroyed by over-voltage surges.  Large appliances like air conditioners or refrigerators are less susceptible, but can be damaged as well. 

Can a surge harm my equipment if I am not using it?

Yes.  Many electrical devices have electronic timers, clocks, or even remote controls (TV, VCR) which remain in operation even when it is not in use.  Also, some appliances cycle off and on at random like air conditioners, water heaters, pumps, or refrigerators and they could be on during a surge condition.

How can I prevent power surge damage?

Because surges can come from many sources the energy professionals at your local electric cooperative recommend a two-stage approach to power surge protection.

Do I really need surge protection?

Yes. Over the course of  the past few years, electronics have become increasingly sophisticated and, as a result, more sensitive. While you may not visibly notice any damage, even slight power surges can shorten the equipment life of today's home computers, VCRs, stereos, televisions, and microwaves.  Although some of this equipment may have minimal surge protection built in, energy surges frequently surpass internal protection levels. 

Do these protectors handle all voltage problems?

No, although they do handle the most frequent and destructive ones.  More sophisticated technologies, such as Uninterruptible Power Supply (UPS) systems are available to provide back-up power to your computer in case of an outage.  UPS systems also provide protection against spikes, surges and sages.  Your cooperative sells a full line of Best Power^TM UPS systems at very affordable prices.

Won't my circuit breaker protect my equipment?

No. A common AC circuit breaker's reaction time is simply not quick enough to respond to most power surges.  The "equipment promoted as part of the Secure Home Program" reduce surges within nano-seconds, whereas a circuit breaker responds in the "blink of an eye," but not soon enough to eliminate the damage effects of surges.
