POWER TRANSFORMER (50 KVA TO 2000 KVA)
[EIRI/EDPR/1408] J.C.184
INTRODUCTION
Over the past hundred years Transformers have played a major role in the growth of almost all industries in the world. The foundation for the ideal of a "Transformer" was laid by Micheal Faraday in the year 1931. While at that time these transformers were having moving parts, the present day Transformer is basically a `Static" device in the sense that they do not have any moving parts that are continuously in motion. Due to continuous efforts of physicists and engineers in the past year, Transformers, underwent many changes, to keep pace with the rapid growth of electrical industries. Now there exists a variety of transformers each differing from the other in its operation, construction, size and applications.
POWER TRANSFORMERS:-
The transformers is a device that transfers electricity or energy from one electric circuit to another without change of frequency and usually, but not always, with a change in voltage.
In India the role of transformers assumes and added significance since in most of the states, electric supplies is are not only erratic but are also characterised by wide variations in frequencies or voltages. These causes enormous damage to the electrical appliance like refrigerators, television and other industrial machinery engaged in the production of commodities. The transformer industry with the help of innovative methods, up gradation in technology etc., will have to manufacture transformers which offer maximum functional efficiency and are at the same time less hazardous or dangerous and economically viable.
