Surge Protector - Computer : What is it?

Surge Protectors Computers

A surge protector is an electrical device that protects electronic appliances from power surges, or quick bursts of high-voltage electricity caused by lightning, wind damage, or faulty wiring. It works by stopping or reducing the power to a safe level. It works on most appliances, including televisions, video players, computers, and cordless telephones. It normally lasts for years, but it needs to be replaced after a high-level power surge. It is generally easy to install and readily available from hardware and electrical stores.

Make sure all your programmable appliances are connected to a power surge, including those that can withstand low-level surges such as televisions, video players, video game units, audio systems, computers, microwave ovens, and home security systems. Also connect satellite TV lines, telephones lines, and fax and modem lines to your surge protector. Check the indicator light on your surge protector regularly, especially after storms. Replace the unit after a high-level power surge to maximum safety and efficiency.

Kinds of Surge Protectors - Computers include the following:

Meter surge protector

A meter surge protector has a surge suppression and protection system to guard against external power surges. It prevents power surges caused by faulty electric service from entering the building. It is usually mounted on the power meter and installed at the service entrance of the building. It is installed by the local power company or licensed electricians.

Electrical panel surge protector

An electrical or service panel surge protector provides the same protection as a meter surge protector. It is installed at the electrical panel, usually at the breaker box. It can be integrated within the panel or mounted outside the panel. While some models allow do-it-yourself installation, they still require the assistance of licensed electricians.

Plug-in surge protector

A plug-in surge protector comes in a box or strip type that plugs directly into a wall socket. It has an LED indicator light or an audible alarm system that alerts the user when it needs replacement. It is readily available in hardware and electronics stores.

Choosing Surge Protectors - Computers (Buying tips)

On/off switch: Choose a surge protector with an on/off switch to quickly shut off power to all components when necessary.

Indicator system:
Look for a surge protector with an indicator light or an alarm system that lets you know if a high-level surge is occurring.

Noise filter: Choose a surge protector with a noise filter system that blocks off unwanted sound and electromagnetic interference.

UL rating: Make sure your surge protector is approved by the Underwriters Laboratory (UL) for safety and efficiency. This is usually indicated by a “UL Tested” label on the package.
