Differences Between Servo Stabilizer and Static Stabilizer

Stabilizers – the ideal electrical devices for voltage conditioning – have become mandatory in numerous applications. The Voltage rises and dips often appear frequently or occasionally – they can be evident in houses, offices, shopping malls, power plants, or industries. Over and under-voltages, sudden shocks, short-circuits, and many other problems are the results of improper voltage conditioning.

The Best Servo Stabilizer Manufacturers in India have been providing distinctive types of stabilizers to overcome the associated defects and correct the voltage fluctuations. Servo Stabilizers and Static Stabilizers are the prominent models of stabilizers used for miscellaneous applications. But many of us confused about what to choose. This post gives you a clear idea of the differences between servo stabilizers and static stabilizers to make the right choice for voltage stabilization for customized applications.

What is Servo Stabilizer?

Servo stabilizers are the stabilizers that work on servo mechanism. They run by the main component called servo motor. It rotates in a clockwise and anticlockwise direction to manage and correct the voltage fluctuations. Assisted by a buck-boost transformer and a variable transformer, the servo motors regulate and stabilize the voltage levels. Servomax Limited, the famous servo stabilizer manufacturer, and others manufacture oil-cooled and air-cooled servo stabilizers for indoor and outdoor applications.

What is Static Stabilizer?

Static stabilizers, as their name says, are static – they don’t have moving parts. Instead, they have an electronic circuit based on Insulated-Gate Bipolar Transistor (IGBT) technology to control voltage. With the help of microprocessors and buck-boost transformers, these stabilizers correct the voltage fluctuations. Spectacular customized models of these stabilizers are offered to the market by many static stabilizer manufacturers to perfectly suit the diversified power applications.

Now that you got an idea of servo stabilizers and static stabilizers, read on to know the differences between the two.

Differences Between Servo Stabilizers and Static Stabilizers

There are many differences between these stabilizer duos. Find here their variations with respect to certain considerations.

  • Working Principle

The working principle of servo stabilizers is the servo mechanism. The clockwise and anticlockwise movement raised by the servo motor mainly corrects the voltage imbalance. Whereas the static stabilizer works on electronic function – based on microprocessors and IGBT technologies, it regulates voltage control.

  • Reliability

The servo stabilizers have an autotransformer that increases or decreases the voltage levels based on the primary and secondary windings. Also, this controls the movement of a shaft that enables the movement of the servo motor to control the voltage. So the voltage stabilization depends on the reliability of the servo motor. In static stabilizers, voltage correction is based on the reliability of the IGBT power stage.

But, to be frank, the IGBT circuits are more reliable than servo motors. So, the servo voltage stabilizers have higher reliability when compared to static stabilizers.

  • Protection Level

The static stabilizers have advanced means like digital signal processors to automatically sense the voltage fluctuation and correct instantaneously to protect the appliances from short circuits and overcurrents. They don’t need any extra hardware parts to ensure protection. However, in servo stabilizers, additional components like MCB and MCCB are needed. So, the static stabilizers have more protection levels than the servo stabilizers.

  • Sound

Servo stabilizers create a little big sound but static stabilizers have silent operations. So, the static stabilizers are preferable to use indoors and outdoors as well. So, if you are seeking for a stabilizer for indoor applications, then it’s better to check for this sound level and select the apt model.

  • Correction Time and Speed

Static stabilizers have a minimum correction time of 20-30 milliseconds and have a very high correction speed of 360-500V/s. The servo stabilizers have the correction time of 50 milliseconds to 5 seconds with a voltage correction speed of 100V/s. So, static stabilizers allow instantaneous voltage stabilization.

  • Auto bypass speed

Static stabilizers have zero transition time – they avoid the break in the output and hence, transfer the bypass automatically. Therefore, it’s easy to enable auto bypass with static stabilizers. However, such means with servo stabilizers are complicated and costly as well.

  • Size

The size of static voltage stabilizers is very much compact when compared to that of the servo voltage stabilizers.

  • Maintenance

Static stabilizers do not have moving parts and so its maintenance is easy. But, the servo stabilizers have servo motors and shaft that move always – therefore, they face regular wear and tear. It’s necessary to frequently maintain the stabilizers. Therefore, the maintenance risks and the associated costs have to be faced when using servo stabilizers.

Ultimately, using static stabilizers is comparatively beneficial when compared to servo stabilizers. With these characteristic features, one can decide well to pertain efficient and standardized stabilizer units.
