How does surge suppressor work?
A surge protector contains metal oxide varistor, or MOV, which diverts any extra voltage to ensure devices receive a consistent power level. The MOV works like a pressure-sensitive valve. When the MOV detects high voltage levels, it reduces resistance. It will kick in automatically to redirect excess voltage.
What is the difference between a surge protector and a surge suppressor?
Surge suppressors differ from surge protectors in that surge protectors are basically just extension cords with minimal built-in protection (fuses, etc.). Quality surge suppressors, on the other hand, should be designed to clamp the voltage before any damage is done to the computer circuitry.
When would you use a surge suppressor?
It’s a good idea to use surge protectors for other high-end electronic equipment, such as entertainment center components. A surge protector will generally extend the life of these devices, and there’s always a chance that a big power surge will cause severe damage.
What is meant by surge suppression?
The diverting and/or diminishing of excessive current and voltage from the AC power line, which can damage sensitive electronic equipment.
Do surge suppressors wear out?
Yes, a surge protector isn’t designed to last forever and will eventually wear out. The bad news is that it’s almost impossible to tell when a surge protector wears out. Which means, you might think your appliances are protected against dangerous power surges when they really aren’t.
What should you not plug into a surge protector?
Avoid starting an electrical fire by never plugging these items into a power strip. Large Kitchen Appliances (Refrigerator, Dishwasher, etc.) These appliances are so high-powered that they’ll easily overload a poor, little power strip. Small Kitchen Appliances. Hair Styling Tools. Extension Cords and Other Power Strips.
Are surge suppressors worth?
Summary. In conclusion, surge protectors are the best way to protect your homes appliances and electrical system from power surges. While surge protectors do come with preliminary purchasing and installation costs, they also provide safety, security, and piece of mind.
Can I plug an extension cord into a surge protector?

Yes , power strip can hold current necessary for TV electronic. But often in instruction manual you can found”plug your TV set in wall outlet directly” . This is because people use power strip many time low grade out of standards.
Should you use a surge protector on a refrigerator?
We do not recommend connecting a refrigerator or freezer to a surge protector. The reason we do not recommend this is explained below: The compressor is sensitive to temperature and current overloads and will shut itself down with a power surge.
Do you need a surge protector?
You don’t need a surge protector for your desk lamp or your standing fan, but you do want a surge protector for expensive devices that have intricate microprocessors, like computers, televisions, stereo systems, and media centers. In short, anything electronic and expensive benefits from a surge protector.
What appliances need surge protectors?
But bigger or more important items, as well as appliances that require constant power, such as computers, printers, televisions, and refrigerators, should all use surge protectors. Any device that you don’t want to lose in the event of a power surge, or that would be expensive to replace, should be protected.
Will a surge protector stop lightning?
The answer? No. By themselves, surge protectors can’t protect your home’s electronics from being damaged by a power surge caused by direct lightning strikes—nothing can.
Does a surge protector only work once?
There’s no exact lifespan we can give you, and it varies from area to area — it depends how many surges occur in your area as well as how many joules your protector can absorb. Many people recommend replacing a surge protector every two years or so, but any recommendation like this one can only be a rule of thumb.
How do I buy a surge protector?
Choose the Right Surge Protector for Your Needs Buy the right number of ports. Consider the gear you’ll plug into the surge protector. Check for the UL seal, and make sure it’s a “transient voltage surge suppressor.” Check the surge protector’s energy absorption rating, and its “clamping voltage.” Check the warranty.
What does a red light on a surge protector mean?
The red protection light indicates that your surge protector is providing surge protection for your equipment. If the red light is out, it means that the surge protector has been damaged by a severe surge and a new one should be purchased.
