... If the gain of the differential amplifier is set to one, then the R3 and R4 resistors form a voltage divider with the ratio of 0.5. Because of this, the voltage on the non-inverting pin of the operational amplifier is equal to Vb, therefore the circuit can be simplified to the form shown in figure ...

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.
