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 / hemanth

While we transmitting the power there is some harmonic
losses so we take multiple of 11kv and also due to form factor
