... resistor values you choose. Is it better to choose high values, or low ones? There are disadvantages on both sides of the spectrum. If very low values are chosen, large currents flow through the divider, which loads the power supply. If very high values are chosen, then the center node doesn’t maint ...

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.
