I explain about working on the ac supply system, single and 3 phase supply-related concepts like line neutral earthing concept, power afctor and rreactive power.
We use the ungrounded electrical system in many places. We will discuss in this post, what is ungrounded electrical system, the differences from a grounded system, its advantages and disadvantages and its applications.

In this article, we will discuss the application of the autotransformer. As an autotransformer is small in size, cost, and weight, and also can provide variable voltage.
So both the step type and variac type of the autotransformer find use in home, industry, and high voltage labs.

In this article, I explain the advantages and disadvantages of the Autotransformer (Auto-transformer).
I will also explain the disadvantage of the autotransformer during fault at the output and also due to damage in a winding.

It is very important to do earthing of the neutral of the substation transformer. You will learn, what are the problems if there is no earthing in the transformer.
I will explain, how the high voltage comes in the transformer without earthing during fault. I will also suggest a very simple DIY project to learn problems.
