Best 5KVA Voltage Stabilizer For Mainline

Great, you’re looking for the best 5kva voltage stabilizer for your home in India and want to know which the best one is?

We think you might have done all your research and found many branded products available in the market but are confused about which one should you buy.

It’s actually pretty much difficult to make a choice. As all of them seem pretty good and they all have rather same features, makes it difficult to differentiate even across brands.

Honestly, we can’t tell you which 5KVA voltage stabilizer for the entire home is perfect.

But only can suggest which are the best for different purposes and you can choose the right one that might meet your needs.

Here we’re suggesting the four best 5KVA mainline voltage stabilizer for homes by studying all their features and customer reviews across India.

How To Select A Right Stabilizer

Before buying a stabilizer you must have to consider certain things. As there are two types of electric appliances: (1) With motor or inductive load and (2) Without Motor or resistive load.

With motor (inductive load) appliances are:

  • All types of fans, ACs, Refrigerators, Water pumps, Washing machines etc.
  • All types of appliances having motor or compressor etc.

Without motor ( resistive load) appliances are:

  • All types of bulbs, Heaters, etc.
  • TVs, Laptops and Music systems, DVDs, Phones, etc.

Impact of voltage fluctuations on appliances with motors (inductive load):

Firstly, appliances with the motor have their own operating voltage range. Like a refrigerator has a much larger operating voltage range as compared to a water pump which has a small operating voltage range.

For example, you might have seen that modern inverter refrigerators work from 90V – 240V, and don’t need any stabilizer, while a water pump works from 160V – 240V, so if the voltage is below 160V, the pump will not work properly, either it will overheat or will make a sound for drawing more current.

And these can cause the burning of the coil or pump and can be hazardous to human life. This applies to air conditioners also as they have a small operating voltage range.

Oppositely high voltage also can be hazardous to both appliances and humans. That’s why we need to install a voltage stabilizer to protect these appliances.

Secondly, in the case of ceiling or table fans, their operating voltage range is quite large and works at any voltage but if the voltage goes below from standard voltage, the fans slow down even you can count the revolution per minute which is very much irritating and doesn’t worth running.

In summers mainly in the village area, the line voltage goes below 150V even 100V in many areas. In that case, you must need a voltage stabilizer.

Peak current :

Another very important thing to be remembered is that all the inductive load appliances need 3 to 4 times more power than their actual power at the time of starting which is called peak current. And after starting immediately it goes to its actual state.

For example, a 1 hp (745W) submersible water pump of rating 5 Amp will take 3 hp (2235W) of power or 15 Amp current at the time of starting. So for running a 1 hp water pump, you need at least a 3 KVA stabilizer, if you use a 1 KVA or 2 KVA stabilizer your system will trip automatically.

That does not mean if you run a 1 hp water pump and a 1 ton AC you need a 6 KVA stabilizer because probably you don’t need to start them at the same time.

Impact of voltage fluctuations on appliances without motors (resistive load):

All types of bulbs and heaters don’t need a stabilizer. When the voltage is less little current flows through them and when voltage is more current flows through them.

Let’s suppose a bulb, when voltage is low the bulb will give less light and when voltage is high it will give more light, similarly, the heater will heat up more and less.

All other electronic devices like TVs, laptops, mobiles, DVDs, etc. have an internal device called SMPS (Switch Mode Power Supply) which converts the incoming voltage to DC 12V or 24V (according to the requirement of the appliance or device) and don’t need a stabilizer at all (extreme low voltage is exceptional).

Figuring out the total load to select the right stabilizer:

The most important thing is that you should be aware of and calculate the total load that you use in your home. If it is not known, then it will be very difficult for you to choose the right fit for your home. Basically, you need to know what kind of electrical appliances you use in your home, the number of hours you spend, and you should know whether the appliance is used all day or not.

Let suppose, you have 10 LED bulbs of 10W, 8 ceiling fans of 100W, 2 table fans of 60W, 1 fridge of 40W, 1 LED TV of 100W, and 1 hp (745W) water pump. So the total load will be 1,905 Watt. Then you need a 3 KVA/2400W stabilizer.

If you add a 1 ton (800W) AC to the system, the total load will be 2,705 Watt then you will have to install a 4 KVA stabilizer. I think you have understood the process.

Another thing to be mentioned here is the power consumption by the stabilizer. The power consumption of a stabilizer depends on the efficiency of the stabilizer. Typically they are 95 – 98 % efficient.

That means they consume about 2 – 5 % of the maximum load. Suppose you are using a 2 KVA stabilizer then it will consume about 100 Watt of electricity.

Which means if your stabilizer is left on for 15 hours a day then it will consume 1.5 unit of electricity. At the end of the month, it will increase by 45 units of extra electricity. You have to pay 250 – 300 rupees extra.
