Why we transmit the power at the voltage in the multiple of
11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told
me that it is due to fomr factor 1.1 of sine wave. its fine
but while transforming we can choose any voltage, so why
only multiple of 1.1 there also.......? plz tell me.

Answer Posted / sharan dilip

it is due to form factor.
FORM FACTOR is the ratio of rms value to average value (
voltage or current)
