Comprehensive Guide to Transformer Mechanics

This course covers the fundamental and advanced concepts of electrical machines, with a special focus on transformers. It starts with the basics of bolt per turn in transformers and moves on to the calculation of primary current in transformers with two secondaries. The course also explains the concept of reflected components in currents and power balance in AC circuits. It further delves into the practical aspects of transformers, discussing the realities of a practical transformer, such as finite magnetizing current, and how to model these realities in an ideal transformer. The course also covers the concept of Eddy current and hysteresis loss in transformers, explaining why they occur and how they can be reduced. Towards the end, the course introduces the concept of equivalent circuit of a transformer, explaining the primary and secondary sides of the circuit, the resistance and reactance of the primary and secondary windings, and the core loss.
