The most fundamental difference between dry-type and oil-filled transformer is that a dry-type transformer has a solid insulating material to provide insulation between conducting parts of the transformer, whereas an oil-filled transformer is one in which dielectric oil is used as the insulating medium. Both transformers have their own advantages, disadvantages, and applications. In this article, we will learn about the major differences between dry-type transformer and oil-filled transformer. But before that let us get an overview of an electrical transformer, dry-type transformer, and the oil-filled transformer. What is an Electrical Transformer? An electrical transformer is a static ...

What is a Transformer? A transformer is an electrical device whose main function is to transmit alternating current between two circuits at a constant value of frequency, but at varying voltage levels. A transformer is constructed by combining two kinds of coil. The first coil carrying the magnetic flux is called the primary coil, while the second coil placed opposite to it, in which electromotive force (E.M.F) is induced is called as the secondary coil. Figure-1 illustrates a standard representation of a transformer. Input voltage at the primary side of the transformer produces the varying magnetic flux on the primary ... Read More

Power transformers and Distribution transformers are extensively used in power systems for stepping up and down the voltage level for various applications such as transmission and distribution. Read through this article to find out the major differences between power transformers and distribution transformers and how they function.What is a Transformer?A Transformer is a static electrical machine which changes the level of voltage and current in a circuit without changing the frequency of the supply. Transformers works on the principle of electromagnetic induction.Based on the design, operation, purpose of use, transformers are classified into different types such as auto-transformer, current transformer, ...
