Distribution Transformers

it depends of the type of connection of coil,

draw the vector system of the primary and resulting vector of secondary with respect to coils winding input, you will see the cause

in a DY connection , the vector representation show a 30 deg lagging

Mr.La Noble,

why ?

Mr.Luv123,

La noble is out of station and his secretary is replying. He will be back next year and reply you as soon as possible.

thanks

Why the the earth is round?

if you use Y-Y connection, there is no lagging, with DY connection you have 30 deg,

why? it is mathematics

Mail me thro this forum's mailbox; I will send you a detailed article - authored by me - on Transformer Vector Group. The article is too long to be directly pasted here.

U always ask for mail ids......but don't mail actually!!!

Not really so! I am so naive that I do not know how to attach files thro this forum's mailbox. I do not find an "attach" button while I try to reply messages in this forum's mailbox - as I find in Yahoo or Indiatimes. Please excuse me. That's why I might have asked for your other mail ID so that I can mail thro my other mail IDs.

Moreover you have also to understand that I am also busy with my regular official work and am in a place where net connectivity is not so good.

So rather than simply pointing an accusing finger, if you can be more specific as to what promises I have not kept for you, even after your abiding my above conditions, I will be able to help you.

"In distribution transformer, the secondary lags to primary" – this is not a true statement. The use of the transformer of vector group Dyn11 is very common in distribution and the phase angle of the LV winding leads the HV by (360-11x30) 30 degrees in this case. However, you can use the transformer of vector group Dyn1 in which case the LV winding lags the HV by 30 degrees.
