SP – Introduction to transformers – e-lesson #2: The basics of transformers

Join us for the second lesson of the Basic level of the Introduction to transformers course by Mr Orlando Giraldo.

This transformer lesson provided an in-depth overview of transformer technology and design. The presenter, Orlando Giraldo, has 47 years of experience in the electrical manufacturing industry and specializes in transformer design, production, and testing. The session covered key transformer concepts like electromotive force, electromagnetic flux, and the role of the transformer core. It also explored the various types of losses that occur in transformers, including core, winding, and dielectric losses, and how these impact efficiency and lifespan. The engineering principles applied in transformer design were discussed, spanning disciplines like electromagnetics, electric fields, and heat transfer. Transformer classification based on factors like voltage, cooling, and mobility was also reviewed. The lesson delved into specialized transformer applications, such as distribution, power, network, and mobile transformers. It highlighted the rise of digital transformer technology, which enables real-time monitoring and asset management. The presentation concluded with a look at transformers in renewable energy systems and innovative solid-state transformer designs that leverage power electronics to reduce size and weight.
