why we not using 230kv directly why we are stepping down and
then stepping up
Answer Posted / a.p.nanjappa
high voltages are safe method to trasfer power generations
bulk power .
High vloltahe are directly used in iron steel factory arc
furnaces -400kv,230kv to 60,30kv arc furnaces, where
generation source very near or long distace net work.
industries adopt bulk supply.
domestic, medium comsummers are 400v,4W,and 230v -mobile
charger ,tv,washing machines, frinders, .....
