... We say that there is a voltage difference between points a and b, with point b at the assumed higher voltage level. We use the words assumed higher voltage level because if this turns out to be a negative number, then a is actually at the higher voltage level. This will be an important concept throu ...

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.
