Transformer parts course, in this course we will learn about the Transformer Parts, focusing on the essential components that make up a transformer and their specific functions. The course will begin with an introduction to transformers, their importance in electrical power distribution, and their basic operating principles. We will then delve into detailed descriptions of each transformer part, starting with the core, which provides a low-reluctance path for magnetic flux, and the windings, which are responsible for voltage transformation through electromagnetic induction. Participants will explore the roles of other critical components such as the insulation system, which prevents electrical short circuits; the tap changer, which adjusts voltage levels; and the bushings, which provide a secure passage for electrical connections. The course will also cover the importance of the transformer tank, which houses and protects the internal components, and the cooling system, which manages the heat generated during operation to ensure efficient performance. Additionally, we will discuss accessories like conservators, breather units, and pressure relief devices, which help maintain the transformer's integrity and longevity. Through practical lessons and visual aids, students will gain a comprehensive understanding of how each part contributes to the overall functionality of a transformer.
