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.

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.
