Unlocked by Huaming: Design of power transformers – e-lesson #2 – Components and calculations
Hosted by: Aleksandar Lojpur
This is the second e-lesson in the Power Transformer Design course, authored and hosted on basic level by Aleksandar Lojpur. More lessons on advanced levels are about to be open for registration. Here you can get the room link for the e-lesson #2.
This lesson provides an overview of the key components and calculations involved in transformer design. We'll cover the different types of transformer tanks, from the common cover design to the more specialized hood type. The active part of the transformer, including the core and windings, requires careful consideration of materials and configuration to optimize performance. Insulation, both solid and liquid, plays a crucial role in transformer operation and must be properly selected. Transformer accessories like bushings and tap changers significantly impact the overall design. Cooling systems are essential to manage heat generated within the transformer. The design process involves numerous calculations to ensure the transformer can withstand various electrical, mechanical, and thermal stresses. By understanding these fundamental design elements, attendees will gain valuable insights into transformer engineering.
