This video-based self-paced course available at Electrician U helps viewers gain a deeper understanding of transformers. This course is a deep dive into the theory of how transformers work, what they are, how to size them, the various types, reading nameplates, sound levels, ventilation, harmonics and k-ratings, and much more. All of our courses are free to our members as well as our yearly continuing education, and all practice exams. Non-members can purchase these courses individually if they’re not interested in membership. We drop a new course like this every month!
