Design of distribution transformers – e-lesson #11: Practical transformer design calculation (elective)

This is the eleventh e-lesson in the Design of distribution transformers course, conducted on the Intermediate level. Here you can save your seat.

This lesson provides a deep dive into the practical design calculations for oil-immersed distribution transformers. The instructor, Mario, guides us through the key concepts and considerations that go into transformer sizing and optimization. We'll learn how temperature is the critical limiting factor, as it directly impacts the transformer's lifespan through an exponential aging process. The design process involves iterative calculations to balance factors like core dimensions, winding configurations, and cooling requirements. Particular attention is paid to managing short-circuit voltage and ensuring parallel operation compatibility. The instructor also highlights emerging green trends, with new efficiency regulations driving transformer designs to become increasingly optimized. By the end, you'll have a solid grasp of the intricate tradeoffs and engineering principles that transformer designers must navigate. This is a challenging but essential lesson for anyone seeking to truly understand distribution transformer technology.
