Answer / vijay yadav
form factor of ac is a multiple of 11
generation is in average value
while ratings are in rms
and rms value = form factor*avg value
so no matter generation is at which value
rms rating will always be a multiple of 11

Answer / suresh apgenco
For HV lines, insulators used are disc insulators whose each
rating is 11kv. based on the point only we are going to
transmit power in terms of 11kv i.e., 11kv, 22kv,... so on.
hence substation ratings are multiples of 11kv
