Even a normal day cannot be imagined without the use of electrical appliances. Not just in commercial spaces and industrial settings, they are also an essential part of our daily lives. However, voltage fluctuations and power surges can cause disruptions in the normal working of electrical appliances. Not just an inconvenience, they can even reduce the equipment's efficiency. These fluctuations can also lead to regular malfunctions and even permanent damage. But with the installation of stabilizer, such things can be prevented. How? What does a stabilizer do? This blog will help you understand the workings of stabilizer, their types and their unique functions.
What Does a Stabilizer Do?
Voltage stabilizers play a crucial role in maintaining a constant voltage supply. An efficient voltage stabilizer will not only ensure the longevity but also the proper functioning of electrical equipment.
A voltage stabilizer is responsible for regulating and maintaining a constant output voltage. This helps to protect electronic appliances from voltage fluctuations. These fluctuations occur due to variations in the voltage from the power grid. This input voltage can be either too high (overvoltage) or too low (undervoltage). A stabilizer ensures that the output voltage remains within an acceptable range. This protects electronic equipment from any damage due to power fluctuations.
A voltage stabilizer functions to regulate and maintain a constant output voltage by automatically performing buck (during high input voltage) and boost (during low input voltage) operations on the input supply, ensuring the output voltage remains within a pre-defined range irrespective of the fluctuations in the input. This process is essential for maintaining excellent voltage regulation and enhancing the efficiency of electronic equipment.
Types of Stabilizers and Their Unique Functions
There are different types of voltage stabilizers that are made for various electrical usage scenarios. Some of the primary types are as follows:
Servo Stabilizers (Servo-Controlled Stabilizers)
Also known as servo-controlled voltage stabilizers, servo stabilizers are advanced stabilizers that offer excellent voltage regulation using a servo motor-controlled mechanism. These stabilizers consist of a control circuit, buck/boost transformer, and a servo motor that continuously monitors and adjusts the output voltage.
They are mainly used for high output voltage accuracy. Servo stabilizers maintain an accuracy of ±1 percent despite input voltage variations of up to ± 50 percent.
Unique functions of servo stabilizers are as follows:
- Ideal for high-end electronic equipment and industrial electrical appliances.
- Provides output voltage accuracy within a very narrow range.
- Offers overload protection and surge protection.
- Works well for three-phase voltage stabilizer applications.
Static Stabilizers
Unlike servo stabilizers, static voltage stabilizers use solid-state electronic components instead of a servo motor. They don't have moving parts as a servo motor. They function based on microprocessor-controlled circuits to regulate voltage fluctuations. These stabilizers consist of IGBT power converter, buck boost transformer, microcontroller, and microprocessor. The microprocessor-controlled IGBT converter generates the correct voltage through pulse width modulation. This voltage is then supplied to the primary of the buck-boost transformer. When compared to servo stabilizers, static stabilizers can produce excellent voltage regulation.
Unique functions of static stabilizers are as follows:
- Fast response time, ensuring stable power supply.
- Ideal for electronic devices requiring precise voltage levels.
- No moving parts, leading to reduced replacement costs.
- Provides better protection against voltage surges.
Relay-Type Voltage Stabilizers
These are the most commonly used stabilizers for home electrical appliances. They function by switching relays to regulate incoming voltage and maintain a stable output voltage.
These voltage stabilizers adjust the input voltage variations from ±15 percent to ±6 percent, with an output voltage accuracy of ±5 to ±10 percent. They are most commonly used for low-rated appliances in residential, commercial, and industrial settings. However, they do come with several limitations, including slow voltage correction speed, reduced durability, lower reliability, interruptions to the power supply during regulation, and an inability to withstand high voltage surges.
Unique functions of relay-type voltage stabilizers are as follows:
- Cost-effective solution for electronic appliances like TVs, refrigerators, and computers.
- Lightweight
- Works within a specific applicable voltage range.
- Moderate output voltage accuracy.
- Provides basic overvoltage protection.
Digital Voltage Stabilizers
Digital stabilizers use microcontrollers and digital circuits to regulate primary voltage variations efficiently. They provide improved precision in maintaining constant voltage.
Unique functions of digital voltage stabilizers are as follows:
- Used for modern electronic equipment like air conditioning units and stabilizer for inverter AC.
- Offers additional features like power rating indication, power consumption tracking, and automatic cut-off.
- Ensures stable flow of electricity with high efficiency.
Choosing the Right Voltage Stabilizer
Selecting the right stabilizer depends on several factors, including the power ratings of the appliance, incoming supply voltage range, and electrical usage. These include the wattage required by the appliance, the level of voltage fluctuations in the installation area, the type of appliance, the type of stabilizer, the working range of the stabilizer, the overvoltage and undervoltage cutoff settings, the type of control circuit, the type of mounting, and other relevant factors.
To choose the right stabilizer, consider the following:
- Identify the power ratings of your appliances.
- Determine the input voltage range.
- Consider the type of appliances.
- Look for additional features like surge protection, overload protection, and energy-efficient design.
Benefits of Using a Voltage Stabilizer
Using a stabilizer for your electronic appliances and electrical equipment provides numerous advantages, including:
- Extended lifespan: Reduces wear and tear on electronic components.
- Cost saving: Prevents frequent breakdowns, reducing replacement costs.
- Better performance: Maintains a steady power supply for uninterrupted performance.
- Protection against voltage fluctuations: Shields devices from unexpected voltage surges.
Common Applications of Voltage Stabilizers
Voltage stabilizers are widely used in various applications, including residential, commercial, industrial, healthcare, and telecommunications.
The voltage stabilizers can be used in various applications, including electronic computers, precision machine tools, computed tomography (CT), precision instruments, testing devices, elevator lighting, and imported equipment. It is beneficial in production lines and other environments where a stable voltage supply is crucial.
This device is also suitable for users located at the end of low-voltage distribution networks, especially in situations where the power supply voltage is either too low or too high, and where there are significant fluctuations. It is ideal for electrical equipment that experiences large load changes and is especially effective in locations that require high-quality voltage stabilization. Additionally, high-power compensation-type stabilizers can be connected to thermal power, hydraulic power, and small generators.
Conclusion
In a nutshell, a voltage stabilizer is an essential device that protects electronic appliances and electrical equipment from voltage fluctuations. Whether for residential, commercial, or industrial applications, a voltage stabilizer is a crucial investment for ensuring the performance of electrical equipment.
