... As you increase the voltage the current through the ladder goes through a rapid rise around 2 V. If it rises quickly to 5 A, pause to allow the system to equilibrate and then continue without allowing the current to pass 5 A. You’ll notice after the system is powered up, the current will drift down ...

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.
