A High Tension Transformer is generally used in power transmission applications, where voltages are very high sufficient to present a safety hazard (for protecting electric equipments from breakdown). High Tension Transformer is used when the current is too high in a circuit to directly apply to the measuring instruments. They are extensively used in meeting and protective relays in the electric power industry.

Key Features

  • Even after the installation of standard off circuit distribution transformer, the voltage fluctuation on the LT side persists due to limited range of voltage correction of the transformer
  • To control the voltage fluctuations, it is ideal to install servo controlled automatic voltage controller either on LT side or HT side Suitable for indoor/outdoor installation
  • Copper wound HT two-in-one system.
  • Problem of low/high voltage on the LT side persists which results in improper operation of the Electrical equipments, premature failure & production loss of a plant
  • The standard off – circuit tapping of transformers can correct limited voltage variation
  • We have developed state of the art technology two-in-one system with transformers having built-in HT automatic voltage regulator
  • L.T. output within /- 1% accuracy
  • Higher efficiency make the distribution transformer to utilize up to 100% capacity

The Unit Consists of:

  • Step down double wound in copper construction
  • On load step less rolling contact type voltage regulator
  • Buck/boost transformers

Advantages of Built-in HT:

  • Space Saving
  • Better Efficiency
  • Protection of Motor etc
  • Reduced Installation Cost
  • Reduction in Electricity Bill

H.T. Stabilizer Comprises of:

  • Step down unit, double wound
  • Buck/boost unit, double wound
  • Stabilizer unit are automatic and motor driven,attached with rolling contacts which helps in winding
  • Manual mechanism for regulation of the voltage at the output side. Control unit
