What Does a Surge Protector Do?

Surge protectors are designed to protect your electrical devices in case of a power surge. They typically work by diverting the excess voltage away from your device and into the ground wire, where it can be absorbed harmlessly. 

It is essential to know what type of surge protector you have installed as some only protect against specific types of surges while others offer more comprehensive coverage. 

It is also important to note that surge protectors will not always prevent damage if an extreme power surge or another event such as lightning strikes near your home. 

The installation of a whole-house generator may be necessary for complete protection against all types of power surges.

How Surge Protector Limit The Voltage?

The surge protector is a great safety measure for any household. If you happen to have electronics, the electricity might fry them if there’s an unexpected power spike or outage that lasts longer than five minutes without protection from surges. 

It may be hard to prove your air conditioner and refrigerator died as a result of a power surge when it’s time to file claims with insurance companies–which makes having one crucial!

One of the most important things you can do for your home or business is preventing voltage spikes. But what if there’s a brownout? Shouldn’t such events be taken seriously, too? 

A Brownout occurs when the power grid isn’t supplying enough voltage to your system, and its lights flicker for a few seconds before returning to normal. Is this event something that should be recognized as another hazard in blackouts? 

In our opinion: Yes! It does not take much time before damage could start happening with machines like computers and other electronics left on during these brief moments without protection from “browning outs.”

What is a Brownout?

A brownout is the opposite of a power surge. When the voltage gets too low, this can lead to what we refer to as “brownouts.” 

Whether intentional like in an emergency load reduction or unintentional, such as when extensive facilities start up and draw down on our grid’s power capacity- these are unacceptable events that should never happen (or at least not for long).

One of the first signs you’ll notice during a brownout is your lights dimming due to decreased voltage. These typically last anywhere from minutes all day, depending on where it starts and how long it lasts before they’re fixed!

What To Do In A Brownout?

Brownouts are common and can happen at any time. They may be a nuisance to deal with, but not nearly as bad as being in the dark without power. 

Fortunately for you, this article will provide tips on what to do when brownouts occur so that your home won’t suffer from extensive damage or have its appliances fried by an uncontrolled event caused by them happening while they’re turned on!

While blackouts are rare (depending on where you live), they always present themselves during high-stress situations like extreme weather conditions like storms and blizzards. 

Blackout prevention is essential because of how long it takes utility companies to turn service back up again once these events occur, which means more stress until everything gets sorted out.

Bad Effects of Brownouts

Computers and other valuable electronic devices are sensitive. The irregular voltage can and will damage them fast, which is why you should always power down all your electronics when there’s a brownout–even if they’re plugged into surge protectors! 

In the case of a low-voltage situation like this one, it’s common to see another power surge as soon as electricity starts powering back up; so make sure that you have some protection for these surges too by installing an appropriately sized breaker or fuse box near any extension cords to avoid fires due to overloading.

The convenience of power strips is what makes them such an essential tool in any household. You can quickly flip the switch and shut down all electronics plugged into that strip from one location in a brownout. If your power surges back on, it won’t be too much to handle, thanks to these clever little devices!

How to Choose the Best Surge Protector For You

Do you ever wonder what the difference is between your surge protectors? Let’s break down some of the basics to look out for when getting a new one. 

One thing that makes it difficult to find a good, reliable, and dependable protector is that there are so many options for getting them from with all different prices. So why does this happen? What features should I be looking at before making my decision or purchase?

Indicator Lights

Surge protectors are a necessity for people who want to keep their electronic devices safe from power surges. You don’t always know when you’ll need one, but it’s essential that the device is up-to-date and working correctly at all times. 

One of the essential features of any surge protector is an indicator light – if this isn’t lit, there may be something wrong with your unit! If so, time to buy a new surge protector before anything happens.

UL Rating

As for power protection, make sure that you invest in a product with a UL rating. 

Also, be on the lookout for transient voltage surge suppressors – many products will have a good safety record but do not provide adequate levels of protection against surges and spikes (even if they happen to carry a UL label).

Clamping Voltage

The Clamping Voltage is the measurement that prompts a surge protector to start redirecting excess electricity away from plugged-in devices. 

In other words, any surge protectors with clamping voltages below 400 volts should be good enough for home use and will trigger earlier than those at higher voltage levels protecting your equipment quicker.

Joule Rating

It’s essential to find a surge protector with the right amount of joules for your household. The higher the rating, the more energy it can absorb and protect you from future surges. 

You’ll want at least 600 Joules so that in case of emergency, they’re not rendered useless!

Response Time

A good surge protector can detect a change in electricity as fast as possible and immediately stops it from damaging your plugged-in devices. 

It’s also essential to determine how long you have before power surges damage your electronics, so try not having any response time below 1 nanosecond. Otherwise, you might end up with some fried electronics on your hands!

Where to use surge protectors?

A surge protector is a device designed to protect expensive electronics by diverting excess voltage from the electronics during an electrical spike. 

Some of these devices have been built into power strips, but they can also be purchased as standalone units with multiple outlets and even USB ports for charging phones or tablets!

A safety precaution that’s easy enough to implement while ensuring you’re protecting your laptop at all times? 

Surge protectors are great not just because they provide protection against spikes in electricity but offer many other features like extra plugs for those who need them and handy USB slots, so you never forget your charger again.

Surge protectors are necessary for all those complex electronics. They’ll help you save money in the long run and keep your appliances from being fried. You need to pick a protector that works with what you have!
