y u ppl bother abt step up or step down,,,,,,,
d question is only concerned with transmission,not with
distribution n use,
so transmission of DC is cost effective when it is used for
large distancess,
but it involves costaly converter stations so it is only
cost effective for large distance,,,
n offcourse it has following advantage over AC transmission
1. it requires only two conductor
2.loss is vey lessthan ac supply
3.no need of capacitor ,inductor
4.corona loss,skin effect are not occur in case of dc
current
now a days HVDC lines are required for grid stability
