Industrial Voltage Stabilizer | Faridabad

Jindal is one of the leading producer & supplier of Industrial Voltage Stabilizer/Servo Stabilizer in Faridabad (Haryana). Our Ranges Of Industrial Voltage Stabilizer is starting from 30 KVA & ends up to 5000KVA

Only selling the product is not our purpose, Our primary aim is to make 100% Fluctuation Free India. Because voltage fluctuation is a common phenomenon in every part of the country. Apart From this, Voltage is low at day time and high at night. So, Becoming South Asia’s Largest Power Control Company, ”it’s our prime duty to provide a constant voltage (400V ±1%)” to every individual industry suffering from Voltage Fever.

Why Industrial Voltage Stabilizer/Servo Stabilizer is Essential For Any Industry.


The industrial units running 24 hours, face the problem of both low as well as high voltage variation. 90% of the industrial load is of motors.

Electric motors draw considerably high current at low and high voltage. This higher current affects the electrical motors (particularly smaller motors up to 7.5 H.P.)

High Current produces higher losses in electrical motors which causes premature failure of winding.

These higher losses of electric motors also increase the losses of cables, switches, transformers, and other associated equipment

For smooth continuous operation of motors, overload relays are usually set at a 20% higher setting. If a single phasing occurs:

  • The line current increase by 1.5 times.
  • If the relay setting is at 15-20% higher than actual running current then the relay will take 4-6 minutes to trip.
  • The motor (particularly smaller motors up to 7.5 H.P.) cannot withstand this high current for such a long time and in most of the cases it burns out before the relay trips.
  • Heavy short circuit current flows through the relays, contactors, cables tec. This further damages the switchgear, and in some of cases may cause Fire also.

With the installation of an Industrial voltage stabilizer and maintaining 390/400 volts, the motor will run smoothly drawing 15-20% lesser current and correspondingly the relay setting can be reduced by 15-20%. In case single phasing occurs, the relay will trip in 40-50 seconds. The motor can withstand the high current for this period and will be safe. Also, the relays, contactors, switchgear, etc. incorporated with the motor will be safe.

Description Of Jindal’s Make Automatic Voltage Controller:-


Jindal’s Automatic Servo Voltage Stabilizer Primarily consists of the following:

  1. Linear type continuously Variable Voltage Regulator.
  2. Double wound buck-boost Transformer.
  3. Electronic control circuit and meter panel.

The regulator and buck-boost transformer are oil-cooled, housed in the same or separate sheet steel tanks. Radiators, if necessary, are provided for effective cooling. The core is built from grain-oriented silicon steel Laminations which keep losses to the minimum and these are wound with electrolytic grade copper to minimize the losses vacuum impregnated and oven dried as per IS.

  • Types Of Voltage Stabilizer/Three-phase Voltage Regulatormanufacturer of Industrial Voltage Stabilizer/servo stabilizer

 

The Jindal’s make Stabilizers are rolling contact type stabilizer with ±254 V &  + 440 V type Regulators.

  1. Series Transformer
  2. Regulator
  3. Control Unit

Series TransformerIt is double wound buck-boost Series Transformers. The primary is fed from the Carbon Rollers of regulator coil. One of Secondary winding is fed with input voltage (Variable) and output is taken from the other end of secondary (fixed).

Regulator The Regulator consists of the Regulator coil, Carbon Roller Assembly, Chain Mechanism and motor gear assembly.

Control Panel It consists of IC Card with suitable Control Transformer for feedback from output and control signals to the motor of a regulator.

The series transformers and regulators are housed in Fabricated Sheet Tank. The tank body is either plane or with radiators according to the requirement of the cooling area. The tank is filled with transformer oil as per IS 335 for the cooling of transformers and regulators. The Control panel is fitted either on the top/front side of the tank or in the separate body according to the size of the stabilizer tank.

The tank has one oil filling hole, One Temp. Guage pocket, two earthing lugs, two lifting lugs, one oil level indicator, 4 unidirectional wheels and one outlet valve for oil.

Working any change in input supply appears at the output which is sensed by the control circuit. The circuit generates a signal according to the variation in the input. This signal operates the motor in the desired direction to achieve the set output voltage. The motor with the gear assembly moves a chain system that moves the carbon roller assembly on the coil. As the rollers move on both sides of the coil simultaneously, the P.D. between the two rollers changes with the movement of rollers. This change in P.D. changes the voltage input to the primary of series transformers which induces a required voltage in the secondary to give constant output.

Benefits of Industrial Voltage Stabilizer


It had been observed that industries usually face the problem of both low as well as high voltage problems. With the installation of AVC and by maintaining 400/230 volts three/single phase – you will certainly achieve the advantages as explained under:

  1. REDUCTION IN BREAKDOWN OF ELECTRICAL EQUIPMENT: Up to 80% depending upon the input voltage variation and working hours of the plant.
  2. ENERGY SAVING: 5-10% depending upon the input voltage variation and working hours of the plant.
  3. REDUCTION IN MDI: There will be a reduction in MDI by 10-15% after the installation of the equipment.
  4. IMPROVEMENT IN POWER FACTOR: There will be a definite improvement in the power factor by 10-15% after the installation of the equipment.
  5. Uniform Quality of End Products.
  6. Better Utilization of Existing Transformer & Cables.
  7. Better production Loss and better efficiency of the plant.
  8. Depreciation allowance @ 80% as per the Income Tax Act.
  • How To Assess The  Possible Savings Before Installing The Automatic Voltage Controller (AVC)

Nowadays every industry is having Electronic Energy Meter installed in your works, you can easily verify and ascertain the ENERGY savings possible by recording the periodic (hourly) readings of KW/KWH corresponding to voltage.

From the recorded readings-different input voltage can be segregated in bands and the corresponding KW consumption. For example, 390-400, 400-410, 410-420, 420-430, 450-460 volts (voltage readings in steps of 10 volts bands) and the relevant KW/KWH consumption readings at particular voltage band can be divided with the number of readings taken to arrive at the average KW/KWH consumption at that voltage band.

From this data-sheet, you will find that overall KW consumption at 390-400 volts by installing the Servo Voltage Stabilizer. (as per the copies of the analysis enclosed)

NOTE: You may be struck out the abnormally High/Low KW/KWH consumption readings from the computed data-sheet, as these may be due to different loading conditions than normal running load. This will result in a more precise and accurate analysis.

Also, you can work out the average monthly failure rate of electrical equipment e.g. electric motors, bulbs, tubes, mercury lights, contactor coils, and electronic circuits, etc. and the expenses incurred in repair/replacement of the same.
