Surge arresters are a cost-effective way to protect your equipment from damage caused by accidental surges. They are not all the same. Here are some tips before you start shopping. If you simply want to add more stores or add a layer of protection between your equipment and the outside world, you should buy a surge protector. With an incredible variety of pricing and features, not to mention an avalanche of questionable marketing promises, it’s hard to understand what’s worth it and what’s silly. To help you figure out, here are nine things to know about surge protection.recommend Phoenix Contact 2818944 Lightning current arrester type 1 FLT-PLUS CTRL-2.5 new sealed
What you should look for in a surge-protector
If you live in a city, there is generally less chance of a big boost in your home and you can probably get a rated voltage of 2000 volts (2kV), while in rural areas you probably need 4000 volts (4kV). The numbers are included in the package.
Protection for communication port connections
Some cards provide protection for communication ports such as coaxial cable, Ethernet networks, modems, telephone and fax lines.
The circuit breakers are not the same
The overload is caused by connected devices that consume a lot of energy, for example, when at the same time consuming devices such as toaster and teapot are used. A circuit breaker is designed to reduce the performance of the card to prevent damage and possibly even fire. Whether over-voltage protection or not, most power cards have a built-in fuse or a circuit breaker. It is important to note that a circuit breaker does not provide overvoltage protection.
Smoothing of energy fluctuations
Energy fluctuations are inevitable and worse in some regions than others. You can damage your equipment in the long run. Some surge protectors and inverters offer line filtering or electromagnetic interference (EMI) with a technical focus. This reduces or eliminates line noise (electrical interference) and provides a cleaner power line that protects your equipment from power outages and surges.
Where Do Power Surges and Voltage peaks come from?
Lightning is known to cause outbreaks. However, power surges can also come from high-power devices that are on the same circuit. These can generate powerful spikes in the power line when turned on and off.
For example, if you have a refrigerator or air conditioner in the same line as your computer, you may experience interference that could damage your computer. Sometimes it can be an unexpected restart. However, it can also cause hard disk crashes that can not be recovered.
The medium overvoltage protection does not protect your radios. If this is a major problem in the area where you live or work, you should consider complete protection of the construction with an external lightning rod that deflects the lightning rods to the ground.
If you are worried, contact your energy company and telephone company. Ask them what precautions they have taken to protect you and what features you have when lightning strikes.
Surge Protector vs. Power Strip
At first glance, surge protectors and electric bands seem to do the same. But while the power strips are essentially multiple output extensions, surge-protectors are designed to protect electronic devices against (as you suspect) electrical surges (and spikes).
The most common overvoltage events occur when energy demand changes, especially if the building has old or faulty electrical wiring. Did you notice that the lights flash or dim every time you turn on the refrigerator, air conditioner, hair dryer, or other high-performance device? This sudden energy demand can lead to a short-term increase in the demanding circuit and affect all connected sockets. In North America, any amount above the standard voltage of 120V is considered excess. Small waves can occur at any time without signal and still exceed the normal operating voltage of a product.Phoenix Lightning arrester FLT PLUS CTRL 2 5 You can check price Phoenix Contact 2818944 Lightning current arrester type 1 FLT-PLUS CTRL-2.5 new sealed
