why transmission line 11Kv OR 33KV,66Kv not in 10kv 20kv?

Answer Posted / kishore

FORM FACTOR of sine wave is 1.11
rms/avg=(im/root2)/(2*im/pi) = 1.11
FF of square wave is 1.00 n triangular is 1.15
so i think form factor is not the only logic behind
11kv/33kv but while the generator o/p formula suggest there
are certain terms multiplied with the form factor(1.11) n
it is forcibly made to a standadadised value by changing
certain parameters..
