What Are The Different Types Of Transformers?

Summary

The power transformer company in India be it the ones working for the requirements of the commercial standards, they provide a range of power transformers which would suit the levels of required outputs for the optimal rates of inputs. The categories available for transformer include electrical power transformer and dry type transformers. As per one of the leading power transformer manufacturers, the range of transformers can only be beneficial if it suits the requirements of the consumers. For instance, if the consumer wants high voltage power transformers but their power transformer suppliers is not in a position to offer it, the latter's credibility will be questioned.

The different types of transformers are based on the network's requirements and the consumer's necessities. Various factors such as environment and voltage levels have to be considered before reaching on the conclusion of which transformer is to be chosen. It is advised to explore the alternatives available for the transformer before selecting any one type, do check the credibility of the transformer supplier.

• Air core transformer

The flux linkage between the primary and secondary windings in an air core transformer is maintained by wounding both of these primary and secondary windings around a nonmagnetic strip. The setup of the primary and secondary windings in an air core transformer facilitates efficiency by eliminating the hysteresis and eddy current losses but the mutual inductance is less when compared to the iron core transformer.

• Autotransformers

On contrary to the prominently used standard transformers, the autotransformers have both the primary and secondary windings connected to each other in series. While the autotransformers are engineered, it is ensured that physical and magnetic linkage between both the primary and secondary windings are connected properly in a series.

• Distribution transformer

The small area required for installation of the distribution transformer makes it perfect for remote locations. In fact, the distribution transformer is also small in size and has a low loss of magnetic energy. Distribution transformer can be used for both domestic and industrial purposes. For the former case, distribution transformer is engineered to handle the range of 440 v to 220 v while for industrial purpose, it is equipped to handle Voltage less than 33KV. The outdoor transformer is a type of distribution transformer.

• Iron core transformer

Since the reluctance provided to the generated flux is high in the air core transformer, the iron core transformers are used for high efficiency which offers smooth linkage between primary and secondary windings. In an iron core transformer, many iron plates are used to wound the primary and secondary windings.

• Power transformer

Whenever the availability for the supply of high voltage is required, the power transformer is used. The power transformer can handle voltage even greater than 33KV. To make sure that safety is not comprised while the high voltage is in function, the power transformers are insulted with proper coverings.

• Step-down transformer

In a step-down transformer, the number of turns in the primary winding is more than that of the secondary windings. As the name of the transformer suggests in itself, step-down transformer necessarily lowers the voltage ratio which is received from the primary voltage. The function of the step-down transformer makes its usage quite common in the electricity distribution network for residential units.

• Step up transformer

The step-up transformers work opposite to the step-down transformer which makes their usage prominent in the connecting transformer of the generator to the grid. The elevation of the voltage ratio from the primary voltage is facilitated by the comparatively higher numbers of turns in the secondary windings than the primary winding in the transformer.
