Three-Phase Transformers Circuits Diagram

In the 1880′s the development of transformers contributed essentially to the enforcement of alternating and three-phase current technology. Transformers enable the transmission of electrical energy using the voltage adapted to power and distance. A three-phase transformer is made of three sets of primary and secondary windings, each set wound around one leg of an iron […]

Spark Firing Circuitry Using a Transformer

The figure below presents an example how a transformer is used to generate the 40kV that fires your car spark plugs. The transformer which is “coil” in the above circuit diagram, used to generate the spark voltage with a very high secondary-to-primary turns ratio.
