Our lives revolve around the use of computers, appliances, and other electrically-powered gadgets, so when a power surge strikes, protecting these devices is paramount.
Surge protection is an investment in your electronics and appliances, as well as your safety. It safeguards your valuable equipment during a power surge that can cause data loss in computers and can damage or permanently disable electronics and appliances.
Let’s see what happens during a power surge, why surge protection is important and how to choose the right surge protection for your home.
The power flowing through the typical wall outlet is considered 120 volt AC power. The voltage is not delivered at a constant 120 volts, however -- it can fluctuate between 0 and 169 volts.
During a damaging power surge, the voltageexceeds 169 volts.
Power surges can originate from an electric utility company duringpower grid switching. They can also occur if there’s a malfunction in a nearby transformer or transmission line. Some of the most powerful power surges can occur as the result of a lightning strike.
Surges can also occur within the home. When a high-powered electrical appliance such as an air conditioner or refrigerator turns on or off, a smaller power surge can occur. Because these appliances’ motors and compressors require so much energy to switch on and off, the brief power demanddisturbs the steady voltage flow in the electrical system.
A boost in voltage above a device’s normal operating voltage can cause an arc of electrical current within the device. The heat that is generated as a result can cause damage to the electronic circuit boards and other components within the device.
Major power surges, such as those stemming from lightning strikes, can cause permanent damage in an instant. But smaller surges, like the ones that occur when your air conditioner cycles on, can cause unseen damage in tiny increments that accumulate over time. They may not disable an appliance in one shot, but they can shave years off the functional life of any device.
There are a few signs that may indicate your appliance or device experienced a power surge:
You can’t prevent what happens outside your home, but you can protect what’s on the inside. Purchasing a quality surge protector, also called a surge suppressor or surge diverter, can help protect your home from damage caused by power surges.
A surge protector diverts voltage spikes safely to the ground rather than letting it enter the sensitive circuits of your appliances or equipment.
The type of surge protector you choose will depend on how you’re going to use the surge protector and what you can afford.
