The document discusses the significance of installing Automatic Voltage Controllers (AVC) to manage voltage fluctuations in industrial settings, emphasizing the adverse effects of low and high voltage on operational efficiency. It outlines the advantages of AVCs, including energy savings, reduced equipment breakdown, and improved production quality. Voltstar is highlighted as a leader in manufacturing various electrical equipment, including transformers and servo voltage stabilizers, with specific models designed for different applications and operational needs.

2. About Us
Voltage variation is common phenomenon. The input voltage is generally low during day time and high during night hours.
Apart from above, few months in a year/few days in a month/few hours in a day the voltage is eighter low or high due to the
following reasons :
Therefore for smooth function, it is suggested to install AVC with ± 15% or 20% input voltage variation range i.e. 340-460
volts or 320-480 different types of models.
In India all electrical equipments are designed for 230/400 volts single/three phase on 50 Hz Indian Standard. After
installation of Automatic Voltage Controller you will have the following Advantages :-
Holidays Peak Hours Rainy Days Agricultural Load Weather Conditions etc.
High Voltage
Low Voltage
Suggestion :
At low voltage you will not be able to operate your machines at rated capacity resulting in lower production.
You need to run the machines on DG set. The power cost of DG set is three times as compared to charge by electricity board.
It is suggested to note down hourly input voltage by installing digital voltmeter at the security gate of
your factory premises for a week.
Check: Failure rate of Electrical Equipments such as Bulbs, Tubes, Chokes, Contactor Coil & Electronic Equipments etc.

The VoltStar is recognized as a leader in the design and manufacturing of
transformers intended to cover the widest spectrum of the world's transformer
applications. Whether it is general purpose requirements for the commercial,
industrial, and utility customer to designing for the unique conditions of India.
VoltStar is considered as one of the upcoming name in the field of Electrical &
Power Equipments. We are engaged in Manufacturing Distribution & Power
Transformers, Servo Voltage Stabilizers, ElectroPlating Rectifiers,
Hydrogenation Rectifiers, Isolation Transformers, Ultra Isolation
Transformers, HT Two in One Systems, HT Servo Voltage Stabilizers,
Automatic Voltage Controller and Regulators, Power Distribution
Transformers, Furnace Transformers, Variable Transformers & Special
Purpose Transformer under VoltStar’s Brand.
Now a days, Fluctuations in the voltage is a constant feature of Electricity supply. The constant fluctuation of a voltage leads to frequent
breakdown and higher rejection in end product manufacturing. We know that 90% of industrial load is of motor. It draws high current at
high & low voltage. This higher current produce higher losses in electrical motors. These losses in motor increase the losses in Cables,
Switches, Transformers, Machine Circuit and other associated equipments & Parts.
This higher current effects the electrical motor (particularly smaller capacity motor up to 7.5 H.P).

3. Specifications
Volt Star's Servo Stabilizers are available in a wide range and various models. The standard Three phase models are suitable
for balanced & unbalanced supply and loads.

Pay Back
It is a equipment, which pays back its cost within 1 - 2 years. Even if you appoint a supervisor to monitor the voltage variation
round the clock. It will cost more than Rs. 10,000/- per month and will be able to record the voltage variation, but shall not be
able to do any rectification.
With the expenses of Rs. 6667/- per month, you will be able to achieve savings of more than Rs. 25,000 / 50,000/- per
month depending upon the input voltage variation and working hours of the plant due to the following advantages;
Energy saving up to 5%
Uniform quality of end product
Improvement in power factor and reduction in MDI
