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

why HT line voltage is multiple of 11.eg11kva,33kva,132kva
