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.
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.
