How Servo Stabilizer is the Back Boon of rice mills in India

In India around 70% of the population earns its livelihood from agriculture. It fulfils the basic need of human beings and animals. It is an important source of raw material for many agro based industries. India’s geographical condition is unique for agriculture because it provides many favourable conditions. There are plain areas, fertile soil, long growing seasons and wide variation in climatic condition etc. Apart from unique geographical conditions, India has been consistently making innovative efforts by using science and technology to increase production.

Major crops grown in India are :- Rice, Wheat , Corn , Pulses, Coarse cereals.

Rice is the most demanding crop from these entire food crop. Reason behind is easy and fast cooking and taste. People choose Pulao over chappati most of the times. And if we talk about South and eastern parts of the India, majority is dependent on the rice.

For example :- In the eastern parts Bihar, Jharkhand, West Bengal and Oddisa popularly known for rice dishes. Same for Southern part ; Kerala, Tamilnadu and Karnataka also known for their rice made dishes like:- Dosa , Idli , Pulao etc.
From many years , India is a leading exporter of rice in the world. The nation produces Basmati as well as other types of rice. This rice production is then sent to different nations. The top 10 Indian states that grow rice are;

  • West Bengal
  • Uttar Pradesh
  • Andhra Pradesh
  • Punjab
  • Tamil Nadu
  • Bihar
  • Chattisgarh
  • Oddisa
  • Assam
  • Karnataka

  • Our rice mills owner have to face so many problems while production of rice. And it's not because of land , weather or anything. It is because of electricity fluctuation. All the time they have to face many problems with electricity fluctuation. Sometimes there is a huge production loss which results in financial loss thus resulting in negative growth.
    If we focus on the main issue of this article , it is Voltage fluctuation problem which affects production as well as owner's financial growth also. To overcome from this situation we have an alternative which is called "SERVO STABILIZER" . But still everyone is not aware with it. And this is our motive to spread the awareness regarding benefits of usage of " SERVO VOLTAGE STABILISER ".
    Servo Voltage Stabilisers controlled stabilization system that performs using a Buck\Boost transformer booster that captures voltage fluctuations from input and regulates voltage to the rated output. Servo Voltage Stabilisers safe guards the Rice Mill Machinery from the voltage fluctuations .

    What happens in rice machinery mills in the absence of a Stabilizer?

    Production of rice in an industry after the farmer’s part is over which includes cleaning batching, polishing, packing, storing etc various kinds of machines are being used which primarily run on power being supplied by State Electricity boards Supply. Three Phase AC Induction Motors, Conveyors Elevators UPS, PLC SCADA etc are vital equipments installed in the plant and their efficiency and life is dependent on the input voltage conditions. Due to continuous voltage fluctuation sometimes machinery gets damaged or doesn’t give the desired performance. Lot of time, manpower and money is wasted on repairing cost.
    Therefore, many rice mill owners are switching over to servo stabilizers to prevent the unwanted problems of voltage fluctuation. To get a good quality servo stabilizer let us have a look at the main features required inside a servo voltage stabilizer.

    Types of Stabilizer -

    1. Relay Based stabilizer

    It is used for low rating appliances in homes, offices and industries. It helps in providing fairly stable voltage for protecting of equipments. They have a Voltage regulation of 9%.At the same time researcher has developed a latest technology called servo controlled system to stabilize the voltage fluctuation rate very quickly.They have a voltage reugulation of 1 to 2%.

    2. Servo Voltage Stabilizer

    In this stabilizer, buck boost transformer primary is connected to the fixed tap of the auto transformer and other one connects with moving arm which is controlled by the servo motor. Apart from it the buck boost transformer primary of servo stabilizer gets connected in the series of incoming voltage. These stabilizers called servo stabilizer because it uses a servo motor to enable the voltage correction. It is mainly used for high output voltage accuracy.
    These stabilizers can be single-phase, three-phase Oil cooled and Air cooled balanced unit type or three-phase unbalanced. In a single phase servo stabilizer, motor coupled to the variable transformer to achieve voltage correction. Meanwhile, in three-phase balanced type, a servo motor is coupled with three auto transformers such that stabilized output is provided during fluctuations by adjusting the output of the transformers. Whereas in unbalanced servo stabilizers, there are three independent servo motors coupled with three auto transformers.

    If we compare servo stabilizers with relay type stabilizers we can find various advantages of servo voltage stabilizer such as higher correction speed, high precision of stabilized output, capable to withstand inrush currents and most importantly the high reliability.

    Features of Servo Voltage Stabilizer :-

  • A) Automatic restart
  • B) Turn on time delay system
  • C) Single Phase prevention & Phase Reversal
  • D) High/ Low cut off, Auto Resumption
  • E) Trip & alarm for Abnormalities
  • F) Neutral Failure alarm and cut off.
  • Benefits of Servo Voltage Stabilizer :-

  • 1. Prevents electricity fluctuation
  • 2. Allows machinery to draw the desired current.
  • 3. Economically viable
  • 4. Gives long life to your machinery
  • 5. Available in different capacity and different input voltage range

  • Therefore to safeguard the Rice Mills Machinery, you have to install three-phase Servo Stabilizer. Many Rice mills are surviving with the help of Servo voltage stabilizers. Now it has become a boon for Rice Mills Machinery to protect it against overload, short circuit, under voltage, overvoltage and other specific requirements.
