You can not lower the load ,capacity, and voltage. To save
energy ,you are left with only reduction of line current to
lessen the I^2R losses.The pf of motor is highest at
full ,or nearly full load.At 35% load ,the pf is less and
hence, the line current is more than required to take the
load (HP)

I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics. Now I have to select vector group of This transformer. To minimise 3rd harmonics, what care should I take in selection of Transformer Vecrtor group? If it is Y-Y with open Delta tertiary then what should be the rating & voltage of Tertiary Winding?
