Description,
I have covered in this course topics that is not covered in any book or online course before.
Explanation is fairly simple yet crystal clear.
You will be able to draw vector diagram and connection of winding without memorizing the diagrams.
Answered why delta is necessary in transformer
What is difference between auto and power transformer
Where auto transformer is preferred over power transformers
What are advantages & disadvantages of auto & power transformer
What are different characteristics of star delta
what is difference between magnetic & electrical coupling
What is advantage of magnetic coupling
what is disadvantage of electrical coupling
What is graded insulation levels.
What is mutual & self induction
Zero Sequence current & neutral current

The generating side of power transformer is generally connected in delta whereas star connection is made on load side. Star-star is commonly used, as it saves neutral insulation and eliminates grounding transformer, in transmission purpose transformers. This configuration is used in most of the systems. For all unit connected generators, Yd or Dy connection is considered as standard connections. Factors useful in designing a system, are many in number, that are associated with the transformer connections. And so the best selection of the transformer connections are determined by the application of these factors.
I hope you will get knowledge of these unique concept.
I am always available to answer your questions online.
