Design of Distribution Transformers – e-lesson #20 – Death valley in transformer projects: when requirements are too demanding

Hosted by: Mario Salano / Master's level
This is the 20th lesson in the Design of distribution transformers course, authored and hosted live by Mario Salano. It is presented on Master's level. You can save your seat here.
This lesson explores the challenges faced by transformer designers when requirements are highly demanding. The presenter introduces the concept of the "Death Valley" - a metaphorical place where designers struggle to meet specifications. The lesson covers the different types of requirements, from mandatory to supplementary and additional. It then walks through a practical 250 KVA transformer design example, highlighting the difficulties in meeting stringent loss and dimensional constraints.The presenter demonstrates how meeting these requirements can push the design process to its limits, requiring creative solutions. He emphasizes the crucial role of clear specifications in guiding the design and aligning manufacturers with customers.The lesson also touches on the influence of standards and other factors like geomagnetic currents. In conclusion, the presenter stresses the importance of overcoming the "Death Valley" challenges for successful transformer designs.
Unauthorized message
Lesson #20 is also the eight e-lesson presented on the Master’s level. It aims to help attendees find a solution when faced with too demanding requirements.
Like in all other lessons of this course, it’s crucial to enhance that the author’s main intention is to provide an overview of transformer design by taking into account stakeholders’ wishes and preferences.

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.
