High voltages vs. Energy loss

The "top line" Voltage is the I x R voltage drop in the line and the bottom line Voltage is the transmission voltage. So loss ratio is effectively resistive_voltage_drop / line_Voltage. So, for a given conductor of resistance R the percentage of power lost will increase as current increases and will decrease as voltage increases.
