Answer / arvind

see there is formula, u must be knowing that
V=4.44FBN, BECAUSE OF THIS 4.44 ONLY U GOT the voltage in
term sof 11, 22 etc this 4.44 u will get from form factor
which has a value of 1.11.

Answer / nilesh dalvadi

Thers is syatem voltage line is of 400 KV and 750 Kvb which
is ot in multiplication of 11 so thers is something more
behinmd 11

Answer / arun

VOLTAGE LINE ONLY DEPEND UPON FORM FACTOR, THEN FORM FACTOR RATIO IS =RMS VALUE /AVG VALUE= 1.11. THEN ONLY HIGH VOTAGE LINE IN MULTIPLICTION OF 11 SERIES.

Answer / prasad

because form factor is the ratio of rms value to the avg
value.normally for AC current we will consider RMS VALUES
ONLY,because of this we will get 11kv,22kv,33kv...etc

I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics. Now I have to select vector group of This transformer. To minimise 3rd harmonics, what care should I take in selection of Transformer Vecrtor group? If it is Y-Y with open Delta tertiary then what should be the rating & voltage of Tertiary Winding?
