Electricity supply is erratic at most places in India(including urban area) with voltage fluctuating in both directions frequently. These high voltage fluctuations can damage appliances, there by causing them to end much before their normal useful life. To address this you need a voltage stabilizer that can save your home appliances. This post will help you find the best voltage stabilizers in India for home use.
Verdict: V-Guard is a standout winner for best voltage stabilizers with Microtek providing good alternatives. Apart from these two, there are other brands such as ServoMate, Accurex, ServoKon, Luminous, IFB, and Pulsetron. However they did not find place in our list as there is not much online details/reviews.
Especially voltage fluctuations are higher in the summer time. Increase in appliance tripping will lead to burning of internal components. Best way to avoid this situation is only by using right voltage stabilizer at home. Check this guide further for more details.

Buyers Guide – Best Voltage Stabilizers in India
Selection of a right stabilizer suiting your applications is critical. The key areas to be considered critically are the nature, power consumption range of your application and the level of voltage fluctuations that are experienced in your locality. You need to know the rating of the equipment to be protected – the ratings are normally mentioned as KW, KVA or in Amps .You will also need to know the nominal line voltage and frequency.
How many appliances can I run on my mainline stabilizer?
This depends on the wattage of the devices you use. You should add up the peak power requirements of all appliance in your household to figure out which stabilizer you should be buying.
Normally, people with multiple phases of electricity in their homes, use one phase dedicated for all heavy appliances like Air conditioners, Washing machines (Especially if you use heated water to wash your clothes) etc.
You can use a mainline stabilizer on the second phase which will run fans, lights, televisions and other smaller appliances.
Do I need to buy separate stabilizers for my appliance even if I have a mainline stabilizer?
It is highly likely that you will need a separate stabilizer for heavy appliances like Air conditioners. If you are not sure, do consult an experienced electrician to suggest you the right combination.
How voltage fluctuations harm your appliances?
Usually, all home circuits have circuit breakers. Therefore, if there is any voltage fluctuation beyond the acceptable limits, the circuit trips thereby protecting your appliances from harm.
Technically speaking, a sudden switch off will not harm your appliance. However, there can be voltage surges during the restoration of the current supply. This surge can damage your electronic appliances.
In the absence of a circuit breaker, low voltage can cause harm to appliances that use motors or compressors.
The solution is to install a voltage stabilizer and ensure that the electric supply to your electrical appliances like AC, TV, fridge, and washing machines passes through the voltage stabilizer.
