HT-Automatic Voltage Regulators

Servokon offers a comprehensive range of HT-automatic voltage regulators that are used for the protection of electric appliances or devices or equipments from overloading of voltage. It mainly consists of two interconnected tanks; one for the buck-book transformers and for housing distribution and the other for covering the servo voltage controller. The main function of the regulator is to filter the fluctuation before feeding it to the transformer. These HT-Automatic Voltage Regulators find its extensive use in industries and chimerical arena for achieving a stable input voltage.


  • In High Tension-Automatic Voltage Regulators, there are helical coils mounted on a conventional laminated core
  • Carbon rollers goes around the length of the coil track & are assembled on a fiber glass carrier board
  • The rollers are connected to the electric output terminals
  • Parallel connection of compensating winding near the regulating coil is done
  • The connection between the windings and regulating coils is short circuited so as to reduce the effect of core-flux fringing
  • It keeps the reactance of the regulator constant at any position of the rolling contact

Technical Specification

  • Solid state relay can sense variations: ± 1% of the rated output voltage
  • Relay operates on: 230 V, 1Ø supply
  • Output Accuracy: +/- 1%
  • Efficiency: above 98%


  • Low maintenance and replacement cost
  • 5% to 10% saving on energy consumption
  • Reduction in breakdown period of the machines
  • 100% capacity
  • On Load step-less voltage variation


These HT-Automatic Voltage Regulators are widely used in industries and chimerical sector for getting a stable input voltage .
