How to Choose Voltage Stabilizers for Our Homes

ridhimalhotra3 May 26, 2016

Power supply in India suffers from myriad shortcomings, erratic distribution being the foremost one. At most places in India, voltage can fluctuate in both directions, both up and down, frequently. These appalling discrepancies in voltage can tremendously damage essential appliances such as refrigerators, TV sets, oven, etc. thereby putting them to end much before their usability has been fully exhausted. Furthermore, in a situation when voltage goes down abruptly, the possibility of electric current in the appliance increases exponentially, which may result in spontaneous burning of the appliance. Which is why Voltage Stabilizers have established themselves as the saviors against fluctuations in many homes and workplaces in India. Voltage stabilizers are equipment that bring back fluctuating or varying power supply voltage to the desired range by using electromagnetic regulators that use tap changers. They help prevent grave damage to devices such as computers, air conditioners and other electrical appliances and at the same time ensure the safety of users. Voltage stabilizers can be easily purchased online nowadays from brands like Vguard, Servokon, Purevolt, etc. that provide you with quality and a solid guarantee.

If you are stuck on choosing the right type of voltage stabilizer for your home or facility, down below are some steps that will guide you in your quest to choose the finest voltage stabilizer that is compatible with your devices.

1) CAPACITY

The first thing to bear in mind is the capacity of the voltage stabilizer you need. The capacity of a voltage stabilizer is measured in terms of KVA or Amps. And, if you prefer using AVR or Automatic Voltage regulator for checking variations in single appliances, then you must check VA rating or current rating of that particular appliance from the specification plate on before buying a voltage stabilizer. Similarly, if the need arises to use a single regulator unit for multiple devices, then for gauging the capacity, you must add up their VA rating or current to get the hang of the total rating.

2) Frequency and Phase

Jot down all the frequencies and phases i;e single phase or three phase of all the devices at your place and your overall load. According to these prerequisites, you have to choose an AC voltage stabilizer with the same phases and frequency. Remember, a three-phase voltage stabilizer is only required for the voltage stabilization of a three phase motor or if the need arises to stabilize voltage in full-fledged three-phase setup.

And, all the appliances that are used at homes usually employ single-phase voltage stabilizers. Moreover, a three-phase voltage stabilizer might not be required for residential usage unless you want to stabilize the voltage of the whole house on a three-phase connection.

3) High and low voltages

Carefully observe and write down high and low voltages of all the devices at your place. To check the voltage for choosing a stabilizer with the right input voltage window, you can make use of a multi meter.

4) Voltage Variation

You must consider the percentage of voltage variation that is sustained by your load before buying a voltage stabilizer. For instance, if you want to power a heater with a voltage stabilizer then you can buy a unit having ±5% output voltage variation. But, if you are using a Voltage stabilizer for a Data Centre server then you certainly need to opt for a stabilizer having a ±0.5% output voltage variation.

5) Sizing

A voltage stabilizer is somewhat similar in size to a UPS or Inverter. You must take into consideration the spacing or the location where you want to install the stabilizer. Ideally, it should be set up in the proximity of the device that it is powering up.

Now that you are armed with some valuation information on voltage stabilizers, here’s hoping you will not face any short-circuits or other voltage related problems in the future.
