Open Delta Transformers


An open Delta Transformer is a conventional three phase transformer manufactured to give a single phase output. The specialist windings used produce a single phase output (which is not in phase with any of the inputs, isolated from all phases (and until tied down earth), any voltage).



Technical Details:


  • 3Ph Power Range : 1KVA to 250KVA
  • 1Ph Power Range : ….
  • Insulation Class : Class H or Class F
  • Frequency : 50Hz/ 60Hz
  • Cooing Type : Dry Type/Air Cooled
  • Conductor : Strips/Wires of Copper or Aluminum as per customer’s requirement
  • Core : CRGO or CRNGO type

Application Areas:


Infrastructure, UPS, Invertors, Telecom, Solar Inverters, Laboratories, Health Care, Data Centers

Key Highlights:


  • Lower loss and greater efficiency
  • Customized Compact Designs
  • Cost effective prices
  • Excellent mechanical and short-circuit strength due to the VPI Process
  • Moisture Ingress Resistant & Immune to polluted atmosphere
  • High grade iron core and winding can be wire or foil.
  • Isolated Local Ground Bonded Neutral
  • There is no relative shift in output, so can be used for unbalanced loads and where harmonics are involved.

These types of transformers are also available with cubicle.
