... The principle of operation of IRTs is as basic as Ohm’s Law: V=IR or R=V/I. The tester generates a known dc voltage (250 V, 500 V, 1k V or higher), chosen by the user, and measures the leakage current from the conductor through the insulation. The resistance is then calculated. The better the insula ...

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.
