Best Mainline Stabilizer

Best Voltage Stabilizers for AC/Fridge/TV/Home in India Review

Going for a mainline stabilizer is not recommended by us since it not only adds up your electricity bill but also doesn’t provide customized voltage requirements by some of your equipment especially electronics which have very little rated amperage.

However mainline inverters are successful tackle high loads of equipment like AC or to some extend fridge and washing machine and very little protection for your television. Yes, if you are having very high fluctuation in your locality, then you may think to go with a mainline stabilizer but you must keep in mind that it will only lower the fluctuation but not of much help against surge protection, overload protection for individual equipment, time delay for individual equipment, etc. Also being in mainline the stabilizer has a 2% electrical losses which means even if you are switching off all your equipment, you will be adding up your energy bill 24X7X365 until your stabilizer is connected or stay charged.

But if you feel like protecting your equipment or are at risk then this model is one of the top picks from our side. This is a 5KVA capacity and hence can easily handle your whole household load (Generally normal houses have a 5KVA connection from their discoms). The stabilizer has an input operating range of 90V-300V. However, the stabilizer will cut off supply if the input feed is beyond the range.

Stabilizer’s Buying Guide

Understanding voltage fluctuations and its reason

Top voltage stabilizers for AC/fridge/TV in India

Voltage fluctuation is the change with the increase or decrease of voltage from the desired range (220-240V). You may have seen it with a change in the speed of your room’s fan or your light getting dimmer and brighter with voltage fluctuations.

Mainly most appliances can operate in the range of 190-240 voltage range without any fatal damage to your appliances.

The reason for voltage fluctuation is mainly due to bad wiring without proper earthling, overloading on the common distribution transformers, switching on high power appliances like AC, motors, etc.

Understanding voltage stabilizers and its working

As the name suggests these voltage stabilizers stabilize the input voltage to the desired output voltage. However, it doesn’t mean that the output of the stabilizer will remain constant. Instead, a stabilizer with an input range of 90V-300V and an output range of 200-240V means that if the input is at 90V stabilizer will ideally give you 200V output while the input of 300V, your stabilizer will give you 240V. In other words during fluctuation in input between 90V to 300 V, your stabilizer output will fluctuate between 200-240 V which is well in the desired range of your equipment.

Stabilizers use an auto-tap changer with auto-transformers in order to regulate the output voltage. The higher operational range of the stabilizer means larger numbers of winding on the transformer resulting in a higher price and weight of the stabilizer.

Choosing your right size stabilizer

The first thing that you should know is the load of your equipment which you can easily find on the label of your equipment. And the second thing that you must know is the range of voltage fluctuation in your locality.

While taking the load find most of the equipment is rated in Watts while your stabilizers are rated in VA (Volt-Ampere) or KVA (Kilovolt-Ampere). In order to relate both the terms, you can refer

0.8 X VA = Watts

Means your AC of 1000W or 1KW needs 1250 VA or Approx. 1.2KVA stabilizer

The above formula is just an approximate way of calculation and you may take it as a thumb rule. However, for exact calculation, you need to do some measurements of your appliances to come up with a power factor, for which you may need a professional.

Now you may have noticed there are various ranges of stabilizers are available at different price points. So you need to select a higher range for stabilizer than the voltage fluctuation in your locality. For example, if Fluctuation is between 170v-240V then you must select a stabilizer with a lower range of 110/130V. This provides a cushion for your stabilizer to get a trip. Stabilizers do have a margin of error of 10% so it is very important to have enough cushion above the margin of error.

Surge protection (Spike Guard) is another important feature that you should look for especially when you are looking for stabilizers for low load appliances like TV, refrigerators, etc. these features protect your appliances from sudden voltage rise during lightning strikes and short circuits.

Do Stabilizers consume electricity

Ideally, stabilizers do not consume electricity but you lose it during conversion between input and output. Generally, a stabilizer operates at an efficiency level of 95%-98% which means they do lose 2%-5% electricity in its transformers winding.

So a 1KVA stabilizer would roughly lose 50 Watts which means 0.5 units of electricity will be consumed for every 10 hours of your stabilizer remaining connected to the supply. It is irrespective of the fact that you are using your equipment or not connected to the stabilizer output.

Talking about a mainline stabilizer, it will be connected to the mainline for 24 hours and 365 days means 438 units per KVA. Assuming per unit price of 4 rupees will lead to whooping energy charges of 2190 rupees per KVA irrespective of you using your home appliances or not.

5KVA mainline stabilizer Rs.10950 per year
10 KVA mainline stabilizer Rs.21900 per year

FAQs: Best Voltage Stabilizers for AC/Fridge/TV/Home in India Review

Why do stabilizers have time delays in their output?

Generally, when you switch on the input to your stabilizers, it energizes instantly but most of the stabilizers meant for heavy loads like ACs have time delay function in their output. As a result, the output of the stabilizer energizes after a small time delay of 1-2 min. This feature enhances the safety of your heavy equipment from getting frequent On-off due to any reason.

Why is my stabilizer making noise?

Well, your stabilizer can produce two types of sound i.e. humming noise which is due to the transformer inside and the other is the crackling sound which might be due to a short circuit or grounding of wires inside the stabilizer. If you are getting a crackling sound, then immediately get your stabilizer thoroughly by an expert as it might further damage the internal components of your stabilizer and also increase the chance of fire hazards.

What do you mean by the cut-off value of a stabilizer?

Your stabilizer is designed to operate at a certain voltage range. If the input voltage range gets out of the designed operating range then the stabilizer automatically cuts off the output supply to safeguard your equipment. So, if your stabilizer has an operating range of 90V to 300V, it means 90V is a lower cut-off value while 300V is the upper cut-off value for the stabilizer.

Why my stabilizer is showing red light with no output voltage?

If your stabilizer is showing red light with no output voltage indicates that your input voltage to the stabilizer is out of operating range. So your stabilizer is in cut-off mode. It is advisable to check the voltage in your home and wait until the voltage comes in the operating range of your stabilizer. If the voltage of your location is continuously out of the operating range of your stabilizer, then you may need to change your stabilizer with a wider operating range as per the voltage of your location.

Conclusion

It is always good to know your load and voltage range in your home before choosing the right size with the right input voltage range of your stabilizer. In the article “Best Voltage Stabilizers for AC/Fridge/TV/Home in India Review”, we tried to put our best effort to handpick the stabilizer models for you. All you need is to know your requirements and select the best-suited stabilizer for your appliance.
