Design of distribution transformers – e-lesson #13 Amorphous Transformers
Event Details:
Join us at Transformers Academy for the new lesson of the Design of distribution transformers course titled ‘Amorphous Transformers’.
🗓 Date: 5th November
🕒 Time: 1 pm CET
📍 Lesson’s author is Mario Salano
In this lesson, we will explore the topic of amorphous transformers – a newer transformer technology that utilizes amorphous alloy cores instead of the more common grain-oriented silicon steel. Amorphous transformers offer significant advantages in terms of reduced core losses and improved energy efficiency, but also come with their own set of design considerations and cost implications. By understanding the properties and manufacturing process of amorphous cores, as well as how they compare to conventional transformer designs, we can gain insights into the evolving landscape of transformer technology and its role in meeting future energy demands.

Lesson 14: Cast resin & dry type transformers
This lesson provides an overview of cast resin and dry type distribution transformers, which use no liquid for insulation or cooling unlike traditional oil-filled units. Hosted by transformer expert Mario Salano, the session focuses on the key characteristics and design considerations of the two main dry transformer technologies – cast resin dry transformers (CRT) and vacuum pressure impregnated (VPI) transformers. CRTs, which encapsulate windings in sealed epoxy resin, offer advantages like better seismic performance and reduced fire risk, though they tend to be more costly. The lesson covers critical design parameters, safety features, and environmental factors driving the growing adoption of dry transformers, especially in renewable energy applications. Overall, the session offers a comprehensive look at this increasingly important transformer technology.
Lesson 15: Leakage inductance considerations and proximity losses
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. It 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. Smart transformers are also introduced – 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.
Lesson 16: Advanced methodologies in custom design with special requirements
This transformers design course with instructor Mario Salano explores advanced methodologies and specialized requirements for custom distribution transformer development. The lesson takes participants on a progressive journey, from slightly special to highly specialized transformer designs. The session covers fundamental transformer principles, including energy transfer and loss minimization, emphasizing their critical impact on efficiency and performance. Through a detailed 2000 KVA transformer design example, Salano highlights considerations around material selection, parameter calculations, and balancing cost-performance trade-offs. The focus then shifts to high-frequency distribution transformers and their role in emerging smart grid architectures, discussing key design challenges such as magnetic materials and thermal management. By the end, participants will gain a deeper understanding of the evolving transformer design landscape and its integration of cutting-edge innovations shaping the future of energy distribution.
