More Details

Description of Automatic Voltage Controller:

Linear, Plus/Minus Type Vertical Rolling Contact Voltage Regulator:

In our regulators, we are using heavy section of electrolytic grade rectangular copper strip instead of copper wire to minimize the losses & increase the efficiency of equipment. We are using self lubricating Carbon Roller Assemblies instead of ordinary Carbon Brushes, which offers more reliability and trouble free performance of the equipment.,

Double Wound Buck/Boost Type Series Transformer:

In our Buck/Boost transformers, we are using CRGO lamination to minimize iron losses and coils of Buck Boost transformer are wound with heavy section of multi strips electrolytic copper to minimize copper losses for getting better efficiency of the equipment.

Electronic Control Circuit and Meter Panel:

Power Automatic Voltage Controller consists of very simple electronic control circuit for monitoring and controlling voltage, repair & maintenance of which is very easy. The regulator and Buck/Boost transformer are oil cooled, housed in same or separate sheet steel tanks. Radiators are provided for effective cooling. The coils of voltage regulator & Buck/Boost Transformers are vacuum impregnated and oven dried as per 15.

    Maintenance Free

    Free Earthing

    It is a type of earthing system which is ready made, standardized and scientifically developed. It's benefits are:

  • Maintenance Free: No need to pour water at regular intervals- except in sandy soil.
  • Consistency: Maintain stable and consistent earth resistance around the year.
  • More Surface Area: The conductive compound creates a conductive zone, which provides the increased surface
  • Area for peak current dissipation and also gets stable reference point.
  • Low earth resistance, Highly conductive, caries high peak current repeatedly.
