    Design of distribution transformers – e-lesson #15: Leakage inductance considerations and proximity losses

    Design of distribution transfomrers - e-lesson #15 - illustration - 850 x 400 px
    Course: Master’s level

    Hosted by: Mario Salano / Master's level

    This is the fifteenth e-lesson in the Design of distribution transformers course, conducted on the Master's level. Here you can save your seat.

    This transformers academy lesson focuses on leakage inductance, a key feature affecting power factor, voltage, and fault currents in distribution transformers. Leakage inductance depends on the transformer's geometry. The lesson reviews the inductance concept, explaining how changing magnetic fields induce electromotive forces. Leakage inductance arises from imperfect winding coupling, causing voltage changes under load, but can also limit current flow. The lesson introduces smart transformers - high-frequency transformers used in smart grids to convert renewable energy. The smart transformer market is growing rapidly. The next lesson will cover design examples of traditional and smart transformers. Calculating leakage inductance involves complex geometric formulas. Minimizing inductance discrepancies is crucial for power converter controllability and efficiency. The future may involve amorphous cores and solid-state components for smart grids.

    The lesson #15 is also the third e-lesson conducted on the Master’s level. This time the author, Mr. Mario Salano, will discuss leakage inductance considerations and proximity losses.

    As in all of the previous and upcoming lessons of this course, here too the author’s main intention is to provide an overview of transformer design by taking into account stakeholders’ wishes and preferences.

    The lesson stays available on-demand upon the live broadcasting.

    About the author

    Mario Salano

    Mario Salano

    Mario Salano was born in Genoa on 13 January 1950. His expertise in the field of power transformers comes from well-established engineering skills acquired in “Salano transformers”, a renowned Italian company that manufactured line-frequency power transformers for Italian power utilities. He is a freelancer in the fi eld of Project Management, Transformers and Electronics, and Outreach Director in NIC-PMI. He has authored two books and has been collaborating with various publishing companies for the past four years.
    His current interests include high-efficiency distribution transformers, the impact of nonlinear loads on power transformers, novel materials for transformer cores and high-frequency power transformers for the use in conjunction with power electronics topologies
