Answer Posted / shahul snfa
if we use 230v,50hz for a load say 100kw. the current for
this supply will be small when compared with 110v,60hz. but
the cable size for 110v,60hz is large due to insulation
size. an most interesting thing is only the cold countries
will use 110v,6ohz supply because the heat dissipated due
to large current will acceptable to their climatical
condition but not for india.. so the supply is depended
upon the country climatical condition and about adv &
disadv........
