why our power production in multiple of 11, in strictlly
asking why our o/p voltage of alternators is 11kv only and
whynot graterthan 15 and016KV?

Answer Posted / somesh upadhyay

the insulater is design for 11kv in xn line so the xn line
vtg are of the multiple of 11.for example 11kv*n=xn line vtg .
if there is a 12 insulater in one string then the xn vtg
will be 11kv*12=132kv.
