Voltage fluctuations are almost common in India, except for big cities like Mumbai and Delhi. Nearly every night, the AC trips up.

The summer months are getting longer, and the frequency of tripping can cause a lot of problems. This is also true for your Led TV, refrigerator, and washers.

You also expose your electrical appliances to danger if you trip.

Installing a voltage stabilizer is the only way to prevent these trips.

Voltage stabilizers: A buying guide

You will often hear the expression “Retirement” when you leave the main cities of India.

 What is voltage fluctuation? 

The ideal input voltage for your home’s electric circuit should be between 220 and 230V AC. What happens if the input voltage falls below 220V, or rises above 230-V?

You may have incandescent bulbs. These bulbs are still used in some homes, even though LED and tube-based bulbs have been introduced. You have probably seen the bulbs dimming so that you can clearly see the filament without straining your eyes.

Low voltage is responsible for this phenomenon. High voltage can also cause extreme brightness. This is how it works. The input voltage can be changed by changing its level. Voltage fluctuation is anything that occurs above the standard 230V.

 Voltage fluctuations: Causes 

Voltage fluctuations can occur for many reasons. Voltage fluctuations can be caused by fluctuation in the input supply to the main grid.

Bad wiring the house Inadequacy in earthing voltage fluctuations can also be caused by these factors. Short circuit voltage fluctuations can also be caused by this.

These can also happen when you suddenly turn on high-powered appliances like AC units, electric motors, and pump sets. Voltage fluctuations can also be caused by overloading.

 Are voltage fluctuations a danger to your appliances? 

Circuit breakers are standard in all home circuits. Circuit breakers protect your appliances from damage if voltage fluctuations exceed acceptable limits.

The appliance will not be damaged if it is suddenly switched off. However, voltage surges can occur during the restoration process of the current supply. These surges can cause damage to your electronic devices.

Low voltage can damage appliances that use compressors or motors if there is no circuit breaker.

 The Solution 

Installing a voltage stabilizer will ensure that your electric appliances such as AC, TV, and fridge are protected from the surges of current.

 The Voltage Stabilizer’s Role 

The voltage stabilizer’s name means that it stabilizes voltage. It brings the voltage within the desired range of fluctuation.

The stabilizer will reduce the output voltage if the input voltage exceeds the acceptable range. The stabilizer steps up or raises the output voltage if the input voltage falls below the acceptable range.

Voltage stabilizers are electronic regulators that use tap changers and autotransformers.

The voltage stabilizer acts as an intermediary between your equipment, and the utility. It monitors the fluctuations and maintains the output voltage within a safe range.

 The right voltage stabilizer 

The load that you attach to the stabilizer will determine the size of the stabilizer. Take note of the power consumption for all appliances you plan to connect to the voltage stabilizer.

The total power consumption of each component gives you the load on the stabilizer, in watts. Sizes of stabilizers are available in Volt Amperes or Kilo Volt Amperes. 1 KVA = 1000 VA.

Your power consumption load is in watts. This figure must be converted into VA.

If your consumption is expected to be 1000 watts, you will need a voltage stabilizer with a capacity of 1200 VA, or 1.2 KVA.

Here are some things to consider when buying a voltage stabilizer

Take a look at the input voltage that can be used in any room of your home. It is usually 230V AC in India.

Take a look at the range of the voltage stabilizer. The stabilizer should be between 150V and 250V. This means that it will turn off the current if the input voltage drops below 150V or over 250V.

If the input voltage falls within this range, the stabilizer will stabilize it and bring it up to 230V AC, which is the desired output voltage range.

Check that your voltage stabilizer is working properly Surge protection spike guards. A surge in input current can occur during the restoration of current, lightning strikes, and short circuits.

In such situations, surge protection turns off the current supply to the appliance and protects it from any damage.

 The main features of a voltage stabilizer 

These are the most important features to consider when purchasing a voltage stabilizer.

Mount of high-level: It is dangerous to place your voltage stabilizer on the ground as it could be damaged or wet.

It is important to place it at an elevated level. This not only protects the device from any damage but also prevents your children or yourself from accidental electric shocks.

Indicators Modern voltage stabilizers have LED indicators that show the input and output voltage.

Galvanometer-type indicators were used in the past. You had to watch the movement of the arrows on calibrated indicators to determine the reading.

Digital models digital stabilizers are versatile and can be used with different appliances. To get the benefits, you will need to connect the stabilizers to your devices.

Time Delay Function Appliances such as the AC or the refrigerator compressors are essential. These compressors require sufficient time to balance current flow in a power cut. These voltage stabilizers have a time delay function that allows for a time-lapse to protect them.

 Protection against Overload 

Modern voltage stabilizers have an overload protection feature that switches off the current supply in the event of overloading or short circuits.

Frequently Asked Questions – Voltage Stabilizers

 Are there multiple-phase voltage stabilizers? 

We have both single-phase and triple-phase current supplies. However, we also have multiple-phase voltage stabilizers. These three-phase voltage stabilizers will only be needed if your motor is three-phase or you need to provide stabilizing voltage for all three phases.

You don’t need to connect the entire house to a voltage stabilizer. These stabilizers consume electricity. These stabilizers can be used for one appliance, such as your AC or TV. You can turn it off whenever you are not using it.

 What current does this voltage stabilizer consume? 

Voltage stabilizers consume electricity, which is something many people don’t know. Their efficiency determines how much energy they consume. A stabilizer that has an efficiency of 95%-98% (the norm) will consume between 2% and 5% of the load.

A 1000 VA stabilizer can consume 50 watts at peak load. The stabilizer can be left on for up to 10 hours, which could result in a consumption of 0.5 units.

 Do you think it is better to have separate stabilizers than a consolidated stabilizer? 

Some electrical devices do not require a stabilizer. Protect expensive appliances like refrigerators, washing machines, and air-conditioners with voltage stabilizers.

As the UPS mechanism of a stabilizer is different, it is better to use a dedicated UPS for computers. Mainline stabilizers should be avoided as voltage stabilizers can also consume electricity. If you don’t intend to use the appliance, you can turn off individual voltage stabilizers.

 What is the idea of voltage stabilizers built into modern TVs and refrigerators? 

Modern TVs, fridges, and AC units all have built-in voltage stabilizers. Voltage management is made easy by electronic circuits such as the SMPS (Switch Mode Energy Supply). Modern LED TVs are capable of working even at low voltage.

They can operate in voltages from 110V to 220V. There is no need for a voltage stabilizer to be used with such devices. These stabilizers are built into all appliances, including refrigerators, AC units, washing machines, and washing machines.

 Are there different stabilizers available for different appliances? 

Each appliance in the home has its own unique features. Each appliance has its own energy limit. You will need voltage stabilizers depending on the energy limit.

These voltage stabilizers are designed by the manufacturers after taking into account the appliances’ energy limits.

There are many voltage stabilizers available for TVs and washing machines. These voltage stabilizers can be found in India.

 Why do LED/LCD TVs require voltage stabilizers even though they already have voltage stabilizers built-in? 

Many LCD and LED TVs have built-in stabilizers that can handle voltage fluctuations between 110V and 290V. These machines do not require external voltage stabilizers. The surge protection feature built into the stabilizers protects them from sudden current surges.

When you suddenly turn on high-voltage appliances such as ACs or electric motors, electrical surges can happen. It can also happen during lightning strikes and short circuits. Sometimes, it even occurs during the restoration of the electricity supply following a prolonged power outage.

 Why use UPS instead of voltage stabilizers for computers? 

While the voltage stabilizer can stabilize an appliance’s output voltage, it cannot store or power-up that appliance. You will need to save work on the computer and turn it off safely in case there is a power outage.

These activities can be done by the UPS, which continues the electricity supply to your computers even if there is no power.

 What’s the difference between an Inverter and a Voltage Stabilizer? 

An inverter converts DC to AC, allowing appliances to function even during power outages. Inverters include a battery that allows you to store electricity for use in times of power outages. This is not what the voltage stabilizer does.

The voltage stabilizer’s job is to stabilize the input voltage and ensure that appliances receive electricity within the specified voltage range (230V). It will not function during power outages.

 What are step-up and stepping-down stabilizers? 

The main responsibility of the stabilizer lies in ensuring that the output current stays within an acceptable range of 220V – 240V. The stabilizer will increase the output voltage to 220V if the input voltage falls below 220V.

In such cases, the voltage stabilizer is called a step-up voltage stabilizer. The voltage stabilizer will reduce the input voltage to keep it within the permitted limits. It acts as a stabilizer by reducing the voltage.
