Design of Distribution Transformers: Introduction – Mutual inductance phenomenon – available on demand!

This is the first e-lesson in the Design of Distribution Transformers course at the Transformers Academy, authored and presented by Mario Salano.

If you have missed it live, attend it on demand here.


In this e-lesson you will learn the fundamental concepts related to the induction phenomenon with a simple analytical approximation of the inductance of two close cylindrical wires and calculation of the mutual inductance between the two wires.

Then basic types of transformers will be illustrated. Finally, principle of operation, equations of transformer MMF and EMF, voltage ratio and the equivalent transformer circuit will be presented.

Each paragraph will be submitted both in general and with reference to distribution line frequency transformer.

Keywords: induction, calculation, equivalent circuit
