Why use a surge protector?
Surge protection is important because even small surges or spikes can eventually destroy or affect the performance of electronic equipment such as televisions, computers, modems and microwave ovens. Damage can occur instantaneously or over time, as small surges gradually degrade internal circuitry. The common use of microprocessors (chips) in home electronics increases the need for surge protection because these chips are very sensitive to voltage fluctuations.
Why is it important to protect phone and cable lines?
These lines carry low levels of electricity, so surges and spikes can enter through those lines and destroy sensitive computing equipment, telephones, televisions and satellite equipment.
What causes surges and spikes?
Power companies nationwide struggle to provide ample clean power to fast growing urban and suburban areas. The result is that the average home or office experiences over 260 power disturbances per year. Even small spikes in electrical current can weaken or destroy vulnerable electronics. Surges and spikes are often caused by a change in demand for electricity, like when a motor or compressor runs on a large appliance. Other causes of surges and spikes include turbulent weather and electric company maintenance.
How do surge protectors work?
Surge protectors act like a sponge, absorbing dangerous excess voltage and preventing most of it from reaching electronic equipment. Like a sponge, surge protectors have a limited capacity to absorb. Once the capacity is reached, the unit is no longer able to protect and should be replaced.
