Surge Protection System is an appliance or device designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or shorting to ground any unwanted voltages above a safe threshold.
When voltage reaches a certain point, a Surge Protection System simply re-route that extra energy with the help of what is essentially a pressure-sensitive valve. With the correct voltage, current flows through as normal, but with a spike or surge, the device kicks-in immediately and redirects the excess.
You should definitely use Surge Protection with your computer. It is filled with voltage-sensitive components that a power surge could damage very easily. Surge Protection System will generally extend the life of these devices, and there’s always a chance that a big power surge will causes severe damage.
Surge protectors will indeed protect computers and other electronic devices from power surges and most distant lightning strikes, but they can’t prevent a direct lighting strike from causing damage to connected devices.
Do Whole House Surge Protectors Really Work? Yes! A whole–house suppressor instantly blocks the surge from entering home circuits to provide comprehensive lightning protection. Individual plug-in suppressors can’t protect electronics that aren’t plugged in, but are hard-wired instead.
Surge protectors don’t last forever. Most estimates put the average lifespan of a surge protector at three to five years. And if your home is subject to frequent brownouts or blackouts, you might want to replace your surge protectors as often as every two years.
Surge protectors themselves don’t “drain” energy. They simply monitor the amount of electricity flowing into the appliances they protect and absorb extra voltage if and when it comes along.
