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
About the author
Mario Salano
Mr. Salano’s expertise in the field of power transformers comes from a well established engineering skills acquired in “Salano transformers”, renowned Italian company that manufactured line-frequency power transformers for Italian power utilities. While inheriting the company from his father, Sig. Mario Salano used his vast engineering skills and he managed to maintain the company in rough period of seventies, adding new technologies and novel approaches to traditional values and products of “Salano transformers”.
His current interests include high-efficiency distribution transformers, the impact of nonlinear loads on power transformers, novel materials for transformer cores and also high-frequency power transformers for the use in conjunction with power electronics topologies.
