In this, I explain about working concept of electrical transformers like a current transformer, voltage transformer, potential transformer, SMPS transformer auto transformer, etc.
You wonder why the electrical transformer rating is in KVA. Why don’t we specify the transformer rating in kW? If you want to know this then this article is for you. Why is the transformer rating in KVA We always specify transformer ratings in KVA or VA. We do not specify the transformer rating in […]

We can check and do a few simple tests of the electrical transformer at home using a Multimeter in a very easy way at home or lab. These simple checks will be useful to find the proper functioning and working of the transformer in any electrical appliances or equipment.
Electrical transformers are used in many electrical equipment. There are many checks and tests performed by the manufacturer of the transformer for the proper function of the transformer using many methods including the multimeter.

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.

In this post, I explain, how to use a CT transformer (current transformer) with an open circuit secondary under certain conditions with a few examples. I will also explain, why high voltage comes in an open circuit, voltage limiting factors, electrical and flux equivalent circuit of the open circuit CT.
