... Resistance is proportional to the length of wire. Thus as the length increases, so does the resistance. It is most efficient to use low current at high voltage. A high current would make P = I2R very large. A lower power loss is obtained for high voltages, since P = (DV)2 / R would not be as large s ...

Voltage optimisation

Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage 'optimisation' devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply.
