why is electricity produced and distributed in multiples of 11. 440V, 11KV, 22KV, 132KV etc..

Answer / abhi

it is due to form factor....but

form factor = rms value / average value

for a sinusoidal supply of voltage in terms of sine wave

ff = a/root 2 (rms) / 2a/pie (avg)
= 1.11

and hence 11*1 = 11 kv
11*2 = 22 kv
11*12=132 kv and so on....
