In these posts, I explain electrical engineering like the working of AC supply, circuit breakers, capacitors, inductors, control systems, Mosfet, thyristors, IGBT, inverters, DC supply, SMPS, power transmission, etc.
I will also cover power factors, reactive power, transformers like PT, SMPS transformer, open circuit current transformer, and also locomotive engine working concepts
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.

We will discuss the need, advantage, and use of neutral in a three-phase induction motor in the complex VVVF (Variable voltage variable frequency) drive system.
You will learn how the use of neutral in an induction motor can make fault finding easy and improve protection and the reliability of the system

I will explain the difference between neutral wire and earth in the AC supply in this technical article. A total of 17 differences between neutral and earth are discussed in this article.
The three-phase AC supply consists of 4 wires. R phase, Y phase, B phase wire, and a neutral wire. In addition to that, we have earth wire also. The neutral wire and earth wire of the AC supply have totally different purpose.

In this post, I discuss: why “power factor correction” and its method, the causes and problems of low power factor, and how to correct power factor and its advantages. You will also learn fixed step type and continuous variable PF correction, the need for fast correction (SVC), and the need for an extra inductor.
There are many more advantages of power factor correction discussed in this article.
I will also discuss extra knowledge as per my industry experience of designing such control equipment. The power factor correction is done for many reasons.
