Introduction To 3 Phase Transformer

The discussion on three-phase systems naturally progresses into a lecture series on three-phase transformers. The lecture centres around the assumption of having three single-phase transformers connected various configurations. The professor goes on to discuss the delta-delta, delta-star, star-delta and star-star connections for primary and secondary coils in a three-phase transformer. Prof. L. Umanand of Power Electronics Group-IISc Bangalore conducted this lecture. Discuss this topic with fellow electrical & electronics engineers, share your ideas, ask questions and doubts in this discussion.
