What is a Voltage Stabilizer? How Does It Protect Your Refrigerator?

Voltage Stabilizer

The voltage stabilizer is an electric device used to stabilize your appliances’ voltage.

If the power supply level in your house dips too low or too high, don’t worry as the stabilizer can keep the level within the range that the refrigerator can withstand.

#1. Here’s how a stabilizer works:

#1. Voltage Regulation:

The input voltage is preconditioned and regulated by the voltage stabilizer at all times.

If the voltage is reduced or increased compared to a pre-established threshold value, the stabilizer reinforces all measures aimed at restoring it to the pre-established value, starting with reducing it.

#2. Surge Protection:

This protection device also provides safeguards against any sudden occasional spikes of voltage that could lead to a short circuit.

#2. How does it protect your refrigerator?

#1. Compressor Protection:

This, perhaps, is the most costly and fragile of all the components of these refrigerators, the compressor, apart from the high-quality compressor.

Any extremes in voltage are, thus it, this unit can malfunction, or get damaged. A stabilizer guarantees that the voltage supplied to the compressor shall not be less or more than.

#2. Maintains Cooling Efficiency:

Temperatures often come short like the refrigeration appliance when hygiene standards are at least important. Without steady voltage, A stabilizer ensures steady power, leading to consistent cooling performance.

Why Use a Voltage Stabilizer?

While some newer refrigerators may come equipped with basic in-built protection mechanisms, they are often not robust enough to handle extreme fluctuations, especially in regions where voltage surges are common.

Here are the key reasons why you should use a voltage stabilizer for your refrigerator:

#1. Protects Against Fluctuations:

Inconsistent voltage can drastically reduce the lifespan of your refrigerator. A stabilizer ensures stable voltage, preventing potential damage.

#2. Prevents Compressor Burnout:

Frequent power fluctuations cause the compressor to work harder, which can eventually lead to burnout. A stabilizer reduces this strain, increasing the life of your compressor.

#3. Maintains Appliance Efficiency:

Stable voltage ensures that your refrigerator works efficiently without increased power consumption due to voltage issues.

how to choose stabilizer for refrigerator?

Choosing the right stabilizer is crucial to ensuring your refrigerator’s safety and efficiency. Several factors come into play when selecting the appropriate one:

#1. Check Device Ratings:

When selecting the appropriate stabilizer, it is advisable that you first look at the voltage, current, and power rating of the devices that use the stabilizer.

This information can be accessed from the specification sticker close to the power socket or the user manual.

#2. Standard Voltage in India:

In India, the service voltage offered is 230V AC at a frequency of 50 Hz.

#3. Calculate Maximum Power:

Multiply the standard voltage (230V) by the maximum current rating of all your devices that will be connected to the stabilizer.

Add 20-25% extra to this number for safety. This will give you the required stabilizer rating.
If you plan to add more devices later, consider leaving some buffer room for them.

#4. Consider Surge Current:

Remember that some devices draw more current when they are switched on. So, consider this “surge current” when choosing your stabilizer.

#5. Power Factor & VA Calculation:

If your stabilizer has a rating in watts (W), use a power factor of 0.8 to calculate the required capacity. The formula is:
W = V x A x pf (where V = Voltage, A = Current, pf = Power Factor)

Example Calculation:

Let’s say the total power (Watts) of the devices you’ll connect to your stabilizer is 1000W.


To convert this into VA (Volt Ampere), increase the value by 20%, so:
1000W x 1.2 = 1200 VA.


Therefore, you’ll need a 1.2 kVA stabilizer.

#6. Stabilizer Working Range:

Stabilizers are designed for use in specific voltage ranges, so we have to understand what these stabilization ranges mean as seen on the label.

Choose the range depending on the extent of voltage fluctuation experienced in your area.

  • Moderate fluctuations? Use a standard stabilizer.
  • Very wide fluctuations? Get a stabilizer with a more wide working range.

#7. Convert Watts to VA:

The formula to convert watts (W) to VA (Volt-Amps) is:

VA = W / PowerFactor(pf)

Since the power factor for most appliances is usually around 0.8, the formula becomes:

VA = W / 0.8

Then, we add a 20-25% margin to the result.

Example Calculation for Refrigerator:

Let’s assume the refrigerator power rating is 300W.

#1. Convert Watts to VA:

VA = 300W / 0.8 = 375VA

#2. Add a 20% Safety Margin:

Now, to account for surges and startup loads, increase by 20%:

RequiredVA = 375VA X 1.2 = 450VA

For a refrigerator with a power consumption of 300W, you will need a stabilizer rated at 450 VA or higher.

How to Use the Table:

Find Your Refrigerator’s Power Rating:

Find the plate on the refrigerator and see how much energy it consumes in Watts (W). For instance, if your refrigerator is a 300W type, look the row for 300W.

Choose a Stabilizer Size:

Make sure you take the value of Final VA with a 20 % safety margin and such stabilizer has to be equal to or greater than the VA rating selected above, for example, 500VA. If your refrigerator consumes 300W, your stabilizer should be rated above 300W.

Check the Working Range:

Higher the fluctuations in voltage in the areas designated will not be, an appropriate working range of stabilizers will be required.

The normal range of household stabilizers is between 150V-280V but in case the household area has very high fluctuations the household stabilizer might not be sufficient.

General Recommendations:

  • Assuming that your refrigerator is small if less than 300W a 500 VA Stabilizer is adequate.
  • For large refrigerators or up to 600 Watts consumption, a Stabilizer of grade 1 KVA can be used.
  • In the case of large refrigerators of around 600W and above then one may require a 1.2 kVA to 1.5 kVA stabilizer.
