Phasor Diagram

(OP)
Hi ,
    This relates to Clarification for phasor diagram.
    My query is as follows,
  

  I want  the phasor diagram properly displayed according
  to the convention of Zigzag Star 0 ,Zigzag Delta 0,
  Zigzag Delta 6,Zigzag Star 6,Star Delta +90,Star Delta
  -90,Delta Star -90 ,Connection of Three Phase Transformer.
  Plz write down the norms & conventions  of drawing
  Such Phasor Diagram.All notation carry usual and conventional standard meaning.
  

RE: Phasor Diagram

Aradhana,

With Star / Delta or Delta / Star connected transformers, 90 degrees phase shift is not possible. You can only have +/- 30 or +/- 150 degrees phase shift.

I think J&P Transformer Book is a good reference in this regard.

Applicable information in IEEE C57.12.70, indexed at standards.ieee.org/reading/ieee/std_public/description/ dtransformers/C57.12.70-1978_desc.html and C75.105, indexed at standards.ieee.org/reading/ieee/std_public/description/ dtransformers/C57.105-1978_desc.html

Busbar,

If anyone copies and pastes the IEEE links you provided in your post, they'll obtain a 404 error.... not found.

Reason: you inadvertently included a space as follows...

.....  std_public/description/ dtransformers/  .....


Eliminating the space as shown below will make it work.

 .....   std_public/description/dtransformers/  ....
