BENEFITS OF INSTALLING AUTOMATIC VOLTAGE CONTROLLER ON LIGHTING LOAD
By maintaining 365 / 210 volts - three / single phase output through Automatic Voltage Controller for Lighting Load, there will be definite saving in power bill & reduction in failure rate of lighting equipments. Higher the input voltage - more will be the savings. The overall effect on the reduction in brightness of the lamp at 210 volts will be negligible.
PAYBACK PERIOD
Owing to its high efficiency and associated benefits, the payback period for the cost of Jindal’s Servo Voltage Stabilizer is from 6-12 months depending upon the input voltage variation and number of working hours of the plant. The HIGHER the input voltage the SHORTER will be the payback period.
DESCRIPTION OF JINDAL'S MAKE  AUTOMATIC VOLTAGE CONTROLLER
Jindal’s Servo Stabilizer primarily consists of the following:

carbon roller assembly : jindal electrical

close view of regulator : jindal electrical

1

Linear Type Plus/Minus type Vertical Rolling Contact type 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 same or separate steel tanks. Radiators, if necessary are provided for effective cooling. Their core is built from grain oriented silicon steel Laminations which keep losses to the minimum and they are wound with electrolytic grade copper to minimise the losses, vacuum impregnated and oven dried as per IS.
 
 
APPLICATION
Though stabilizers are useful for any kind of application, these are most suitable for 24 hour continuous process plants where breakdowns due to fluctuation results in heavy financial losses. These include :
  • Cement Plants
  • Flour Mills
  • Engineering Units
  • Pharmaceutical     Units
  • Cold storages
  • Rolling Plants
  • Textile Mills
  • Paper Mills
  • Tube Mills
  • Rice Sheller's
  • Rubber Industries
  • Tea Estates
  • Food Processing    Units.
  • Oil and Vanaspati     Plants.
  • Footwear and    Leather Units
  • Distilleries &    Beverages
  • Hospitals
  • Nursing Homes
  • Clubs
  • Hotels
  • High Rise Buildings
