How is an oil transformer diagram structured?

An oil transformer diagram typically includes key components such as the core, windings, oil tank, tap changer, cooling system, and bushings. The diagram illustrates the primary and secondary windings, showing how electrical energy is transferred and transformed between voltage levels. Additionally, it depicts the circulation of insulating oil, which cools the transformer and provides insulation. Properly indicating the connections, grounding, and protective devices enhances the diagram’s clarity. Understanding the structure of the oil transformer is essential for effective maintenance and oil testing of transformers to ensure optimal performance and longevity.
