As there is no rotating or moving parts, a transformer is classified as a static device. Transformer operates on an AC supply. Transformers operate based on the principle of mutual induction.Power transformers are called heart of power system, they are essential part and required for transmission and distribution of power supply.I have prepared this course considering theoretical and practical aspects, you will certainly feel the difference when experience professional is delivering the knowledge. This course consist of 164 Video Lectures and total duration of 11 Hours. This is the most comprehensive training online for transformers.Find below details of topics covered in this training.Topics covered in Part 1:1 Transformer Definition and Uses2 Can transformer
