This water has led to a hydroponic system where the by products from the aquaculture are filtered out by the plants as vital nutrients, after which the cleans ...
Current Transformers
Current Transformers

... A current transformer is an instrument that transforms one current value to another current value (e.g. 100A to 5A.) The advantage of using a current transformer in an industrial context is that it provides galvanic isolation from the voltage on the primary winding while simultaneously furnishing a ...

... Lenz’s Law is a result of conservation of energy. We know that energy cannot be created or destroyed and as a result of this, Lenz's law applies to the generation of back emf in motors (and the motor effect). It applies as following: If we have a current flowing through a wire in the presence magnet ...

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.
