Hydraulic-Electric Analogies — Part 7: Variable Electrical Transformers (.PDF Download)

    Oct. 9, 2014
    Analogies between hydraulic and electric transformers, though not considered practical, revolve around magnetism and flux.

    Variable electrical transformers, often constructed as “auto-transformers,” are available from a number of manufacturers. They’re constructed much like that of a normal ferromagnetic, toroidal (donut-shaped) core as a...
