What is Servo Voltage Stabilizer?

A servo voltage stabilizer is stabilizers, which constantly monitors as well as provide the constant output voltage. In addition, it controls the variations in the input voltage by the movements of a motor. Motor Movement is either in Clockwise or in the Anti Clockwise direction.

In short, it automatically regulates the voltage. It also considers a cheap as well as a good voltage stabilizer. Moreover, this is a perfect solution to protect the appliances from voltage fluctuations.

Thus, We Balaji Power Automation are leaders in servo voltage stabilizers manufacturers in Delhi, India, And offer best Servo stabilizers.

Types Of Servo Voltage Stabilizer?

Basically servo voltage stabilizer is of two type on basis of Voltage:

  • LT Servo voltage stabilizer/ Regulator 
  • HT Servo voltage stabilizer/ Regulator  

LT Stabilizer/Regulator:

LT Automatic Voltage Stabilizers hold their potential too for units having either LT Supply or low capacity HT connections also. In short LT Servo Stabilizers prevents direct exposure of fluctuating voltage to critical electrical equipment in any establishment.

It also prevents frequent tripping of overload and over/under voltage relays to ensure uninterrupted production. These designs for Balance Supply & Unbalance Loads as well as Unbalance Supply & Unbalance Loads. Even so, The range of input supply for the stabilizer depends upon the voltage condition at the supply point.

What are problems due to Fluctuation?

HT Stabilizer/Regulator:

In short, the High Tension Automatic Voltage Regulator or built-in AVR is the high-tension stabilizer. Whose job is to protect the electrical/electronic devices & to conserve energy also by supplying a stable and continuous input voltage. We at Balaji Power Automation, manufacture a wide range of HT-Automatic Voltage Regulators.

Usually, a distribution transformer generally Steps-Down the voltage from H.T. to L.T. However, it cannot take care of the fluctuating voltage and most of the time and at most of the sites. In addition, It realizes that the problem of fluctuating voltage remains, which resulting in improper function of electrical systems.

Thus HT Transformer with Built-In HT Automatic Voltage Stabilizer provides total solutions for voltage fluctuation and stabilization. Actually, the unit is a combination of HT Automatic Voltage Stabilizer as well as standard Distribution Transformer working in conjunction.

What is the importance of a servo voltage stabilizer?

It is always important that you have an electrical supply with a steady voltage. However, Fluctuation is Occurs due to Long Transmission Line in India as well as in World.

Industrial motors are heavy motor, which needs very stable AC voltage & current all the time for a smooth function. However, as usual due to fluctuation, the industries have to face a huge loss. Due to High/Low Voltage Supply, the failure of the motor or voltage-sensitive devices Occurs. The Whole Production Unit effects due to this.

A stabilizer is highly important for optimum performance of any electrical/electronic equipment that also maintains input mains voltage stability. For overcoming such a grave situation, choose Balaji Power Automation Voltage Stabilizer.

 Therefore, as Servo stabilizer manufacturers, we ensure that the load is operating within safety limits. And machines operate at a better efficiency with avoiding losses by choosing our Servo Stabilizer.

Especially, When you have a workplace running 24/7, the Servo voltage stabilizers are Highly recommending. Moreover, We Servo Stabilizer India offer Servo Voltage Stabilizer for all industrial needs

Need of Voltage Stabilizer?

Although, there is no surprise in saying that voltage stabilizers use for providing right and stable voltage. To different types of electrical appliances. The electrical equipment is design for a wide range of input voltage. So, depending on the sensitivity working range of appliances is limit. Therefore, voltage stabilizer helps in ensuring that fluctuation in voltage does not affect the load of the electrical appliance. At the coming power supply.

Circuit Diagram

Components Of Servo Stabilizer Or Automatic Voltage Regulator.

Servo motor controlled Automatic voltage stabilizer consists of following components There are main components in a Linear servo voltage stabilizer:-

(Please refer servo stabilizer circuit diagram shown below)

  1. Linear ± Type Vertical Rolling contact voltage Regulator
  2. Double Wound Buck /Boost Transformer
  3. Servomotor – Synchronizing Motors.
  4. Electronic Control Circuit and meter panel

Linear ± Type Vertical Rolling contact voltage Regulator:

This is Vertical in shape & this Section consists of an Electrolytic grade rectangular copper strip instead of copper wire. To minimize the losses & increase the efficiency of the equipment. When the Vertical Coils ready then it dips in transformer varnish to enhance the life of the coil.

Basically this consists of the Carbon Roller Assembly. The Carbon Roller is Moving part in servo stabilizer. The voltage fluctuation totally depends on the carbon roller. So, as a servo stabilizer manufacturer, we suggest & use the high-Quality carbon roller of Reputed manufacture in India. Actually, This is also self-lubricating carbon roller assemblies, which offer more reliability and trouble-free performance of the Equipment.

Double Wound Buck /Boost Transformer:

This Transformer connects between mains input and output of load terminals. This knows as Series Transformer also. Especially, We are using CRGO lamination to minimize iron losses & coils of Buck/Boost transformer. This also contains the heavy section of multi strips, electrolytic copper, to minimize copper losses. For getting better efficiency of the equipment too.

Servo Motor- Synchronizing Motor:

The Servomotor is an also valuable part of the servo stabilizer. Because of the motor move in either clockwise or anticlockwise direction. This moves the carbon roller assembly in Vertical Upward or downward according to the input voltage. Generally, Servo motor is an AC Synchronous motor that fits on top of the Voltage Regulator part.

Electronic Control Circuit and meter panel:

Especially, the Electronic control circuit is the main part of servo stabilizers. Because of its analysis of the input voltage & feeds the signal to various parts like Servo motor, Regulators, etc.

So, all parts work according to that signal after that we will get a constant output voltage.

Balaji Power Automation Meter Panel also consists of a very simple electronic control circuit. For monitoring and also controlling voltage, repair & maintenance of which is very easy.
