  hi frnz
  can any one tell me about how to make connection taking the main line from the home to directly to transformer??

  Pls tell the input and output rating of the transformers Its turns ratio The output voltage it must provide and stuff
  
  Other than that this is like a blindly letting us in some forest

  i am talking about the 3 phase transformer the current thow which is drawn into our homes

  A transformer has a primary side and secondary side. The input goes to the primary and the output is taken from the secondary. Based on the number of turns in coil in primary and secondary, the transformer may be step-up or step-down.
  
  Distribution transformers have a star connected secondary so that the neutral is available. The three phases at the distribution side will not be uniformly loaded (that is practically impossible as loads tend to fluctuate a lot) and that is why the secondary is star connected to get the neutral. Well, there has to be a return path for the current!
  
  You may elaborate your query so that we'll get a much clearer picture.

  ok lets start from the beg....
  at 1st
  
  why 3 phase??? why not 6 or 9 phase

  Each phase has a dedicated winding in the alternator. These windings will be displaced 120 degrees electrically for three phase output. Say if you need six or nine phases, there has a to be a lot of space to accommodate six windings at 60 electrical degrees or nine windings at 30 electrical degrees for the same output as the three phase. Practically isn't possible as the machine will have to be constructed with huge dimensions. And besides, a six phase system can be considered as two 3 phase systems and a nine phase system as three 3 phase systems. It is all basically three phases!

  i am very sory but i am not so much clear by this explaination..
  will you please elaborate??

  I wasn't talking about the transformer, but the alternator. I hope you are familiar with the alternator basics and working. Do ask if it still isn't clear.
