Electric transformers are complicated pieces of equipment that can be built to fit a variety of constraints. Every transformer has the basic purpose of transferring electrical energy from one circuit to another using inductively coupled conductors. These mechanisms rely upon two important principles, namely: electromagnetism and electromagnetic induction. In other words, it is first important that electric currents can produce magnetic fields and second that those magnetic fields can change in a coil of wire and induce a voltage at the ends of that coil.

While the basic structure of electric transformers is essentially the same across the board, the exact specifications are extremely varied. Transformer cores come in a variety of shapes and materials and they can range in size from the miniscule ones that might be found in household electronics to the enormous ones that are used for entire power grids. The size of the transformer greatly effects how efficient it is. Energy dissipates into the cores, windings, and surrounding structures of the mechanisms making them less than 100% efficient. In general, the larger the transformer, the more efficient it is. Small electric transformers tend to lose more power than larger ones in the process of energy transfer. While size is an important factor, it is hardly the only thing that must be considered.

You can classify electric transformers by frequency range, by application, by power capacity, by voltage class, by cooling type, and by several other categorizations. Understanding exactly which type of transformer is ideal for your needs can be a challenge. At the Coil Winding, Insulations & Electrical Manufacturing Exhibitions in Mumbai, Chicago, and Berlin, you will be able to find experts in their field who can give you all of the information you need to get the right equipment for your purposes. Before the exhibition is over, you will find exactly what you need and you will have made valuable contacts in the industry.
