Multi Tap Transformers


  • K Rated transformer for converter application
  • Equivalent rating calculation considering overloading and Harmonics
  • Designed for reduced harmonics
  • Complete range of Perfect Harmony series
  • Earth shield between HV & LV windings to avoid transfer of high frequency transients to HV/LV side
  • Suitable for Solar load profile
  • Inverter windings are specifically designed to withstand voltages excursions that arise due to pulsed mode inverter operation
  • Inverter windings are capable of withstanding voltages with rate of rise (dV/dt ) up to 500V/µs to ground
  • Galvanic ally isolated inverter winding for each inverter
  • Electrostatic shield between inverter winding and MV winding
  • Inverter winding could be star/delta. In case of star winding neutral not to be grounded
  • Low no load losses


Power transformers are available for both indoor and outdoor applications.

  • Renewable energy (Solar applications)
  • Multi Tap Transformers are used in heating element applications
  • Industries (Sugar, Mining, Transportation, Textile, cement, steel & Automobile)
  • All Drive OEMs
