# System Loss In Terms of I why not V?

We all know that the system loss in transmission line is i^2R. So, in order to reduce the loss we diminish the current flow through the line by means of transformer.
My question is i can also calculate system loss by the formula v^2/R where v is the potential across transmission line. So, shouldn't we reduce the voltage instead of current in that sense?
