Answer / k.prakashchandra
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)
