What Is A Surge Protector?

The advancement of technology has made us purchase loads of advanced electronic products but you know that keeping them all at your space might be a bit dangerous. Wonder how?

Power fluctuations can cause incredible damage to your property. That’s why every time you purchase an electronic appliance, there’s one thing that you should never forget to put in your cart that is Surge Protectors. Yes, surge protectors are a saviour from a lot of miseries and losses.

This device lets you connect multiple electronic devices together and also helps in managing the power flow.

In this article, we’ll give you a complete brief about Surge Protectors and how they’re your saviour.

What is a Surge Protector?

Let’s begin with knowing what surge is.

A Surge is an abrupt voltage or power rise in the circuit lines above a certain level, which scorches or demolishes the gadget’s circuits entirely or partly, depending on how much time the surge passed through the gadget.

Surge is an uncommon phenomenon, which arises due to a lightning strike on an open wire or due to overloading of power sockets by operating appliances of high power needs.

A Surge Protector is a device that serves two main purposes.

  • First, on a general basis, it lets you use multiple socket plugs while occupying just a single plugin in the socket.
  • The second one, which is the most significant function is that it protects the devices and appliances connected through it from an unexpected surge or spike.

Although surge arises much rarely, when it occurs, it might deteriorate the appliance circuits completely.

Surge Protectors are used in electronic devices, which need high electrical power to work such as Air Conditioner, Refrigerators, Compressors, and a lot more.

How it Works?

A standard Surge Protector works by executing electrical current through the socket to several electrical socket plugins on the surge protector. Therefore, this offers you multi-socket plugins just by connecting it to a single electrical socket.

But a surge protector works differently during a Surge.

  • During a surge, an electrical component attached in the Surge Protectors, called metal oxide varistor (MOV), which is a voltage-dependent resistor acts as a surge detecting sensor.
  • It is the time when an additional amount of current or voltage flows than the common voltage.
  • Here to secure the device, the MOV diverts the extra current to the outlet’s grounding wire by creating a low resistance in it.
  • This grounding wire then runs parallel to the hot and neutral wires of the Surge Protector.

Therefore it provides an alternative pathway for extra surge voltage.

In normal conditions, when standard voltage flows through the circuit, the MOV creates very high resistance in the grounding wire, which prevents any voltage diversion and thus provides constant voltage in the sockets.

Things you Should Know About Surge Protectors

1. Cheap Surge Protectors

If you think buying a cheaper one can make the same difference as the good quality ones, then no you’re mistaken. As the cheaper ones cannot handle high voltage fluctuations.

2. Power Strips are different than Surge Protectors

These two things are absolutely different from each other. Surge protectors offer you great support to control power surges whereas a power strip offers you multiple connections and does nothing to help you with electrical problems.

3. Joules

The protection amount displayed on the Surge protectors is called joules. This states that the more amount of joules shown on the protector, the more number of voltages the surge protector can handle. The amount of joules is shown in MOV.

4. No power conditioners needed

Don’t fall in the traps of conditions that various companies offer to you. Every electrical device can hold up to 120 volts of power. They also carry filters, which ensure no noise and turn them into a component your device needs.

But just in case, you’ve purchased a cheap brand product, you might need a conditioner but if not, your surge protectors are enough.

5. Multiple outlets than needed

It’s always a good thing to get a surge protector that has more outlets than you think is required. As you never know where and how you might need to connect appliances.

6. Warranty

The majority of the brands offer a warranty on their surge protectors. One of the brands offers a warranty of 25000 rupees. This is extremely important as if any accidental calamity occurs and your device outbursts you can claim the respective amount.

7. USB

Usually, surge protectors that are purchased are the common one’s but look for options, which also offer you a USB socket to the plugin. So that charging your devices can be quick and direct.

8. Save your pockets

Many routers are available with protectors, alongside a lot of companies offer you surge protectors with your electrical product at cheaper rates. But you need to make a choice wisely. The complete game is about joules. So check the joules capacity before you make a purchase.

9. Surge protectors with huge spaces

Since a surge protector has multiple socket plugins but opt for one that has good space between each socket or has a function where the sockets can be swivelled. This will give your hefty plugs enough space for plugins.

Frequently Asked Questions

1. Is there any Disparity Between surge protector and a Power Strip?

Definitely yes, there are multiple differences between the two of them. The strip provides you with additional sockets to plugin different electrical appliances. However, it is not a solution to your electrical issues like an overflow of electricity or fluctuations.
On the other hand side, a surge protector keeps your devices safe and secured by stabilizing the power flow of current.

2. What makes a power surge different from a power Spike?

In simple terms, both of them, a surge or a spike is extremely harmful to your electrical appliances. They harm in different ways but the harm is equal. A power spike is a short amount of pulse from the power line, which occurs for some milliseconds but damages your devices.
Whereas a power surge is an incident, where the electricity flows with an extremely high amount of voltage that harms your devices.

3. What is the actual life span of a surge protector and when are we supposed to get it replaced?

A surge protector doesn’t last long. The maximum life of a good quality surge protector is up to five years. But also keep in mind that if your residence or commercial space is prone to power breakouts, fluctuations, then it may last for two years.
It’s good to get your surge protectors replaced after three years but as mentioned if your space faces breakouts usually, then replace them in two years.

4. Is it okay to plugin a Surge Protector in an Extension Cord?

Firstly you need to make sure that if you’re plugging in a surge protector in an extension cord, then the extension wire needs to be long enough and has the capacity to bear the power flow. If not, this might result in a blaze.

5. How can I choose a good surge protector?

You can look for the energy absorption capacity and the energy clamping voltage a surge protector has. Always look for a protector that has seven to six hundred joules or more. The higher the joules, the better the surge protector.
