Understanding Transformers and Electrical Machines

This course covers the comprehensive study of electrical machines, with a special focus on transformers and phase conversion. It delves into the different connections of three-phase transformers, such as star, zig zag, and delta connections. The course also explores the concept of phase conversion, particularly the Scott connection, which is used to convert a three-phase balanced voltage to a two-phase balanced voltage. It further discusses the application of two-phase induction motors in control systems and other applications. The course also provides an in-depth understanding of the parallel operation of transformers, their construction, and operation. It concludes with a detailed discussion on the cooling mechanisms and tap changers in transformers.
