It is has advantage?let see
power= VICOS(@)
when voltage is reduced,current increases to keep the power
constant,
consider that ur going to export 500w power to user
current(i)=500*0.8/110=3.63A
if its is 230 v
current(i)=500*0.8/230=1.73 A
note that current is nearly doubled it will increase the
conductor cost and breaker rating etc.
110 v transmission line requires conductor of more capacity
when compared to 230 v
