Surge Supressors Explained

A power surge, or transient voltage, is an increase in voltage significantly above the designated level in a flow of electricity. In normal household and office wiring in the United States, the standard voltage is 120 volts. If the voltage rises above 120 volts, a problem exists, and a surge protector helps to prevent that problem from destroying your computer. Even if increased voltage doesn't immediately break your machine, it may put extra strain on the components, wearing them down over time. A standard surge protector passes the electrical current along from the outlet to a number of electrical and electronic devices plugged into the power strip. If the voltage from the outlet surges or spikes -- rises above the accepted level -- the surge protector diverts the extra electricity into the outlet's grounding wire.

Usually a varistor, also known as an MOV, connects the power line to the ground. When the voltage spikes, these varistors allow the current to run to the ground and dissipate the surge. When current returns to normal, the varistors have higher resistance that prevent normal current from traveling to the ground. Another method uses a gas tube in a similar parallel circuit to perform the same job as the varistor.    Learn More. . .
