A distribution transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. If mounted on a utility pole, they are called pole-mount transformers (or colloquially a pole pig). If the distribution lines are located underground, distribution transformers are mounted on concrete pads and locked in steel cases, thus known as pad-mount transformers. Because of weight restrictions transformers for pole mounting are only built for primary voltages under 30 KV.
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 an added significance since in most of the states; electric supplies are not only erratic but are also characterized 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, upgradation 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.
With some fast moves at launching fast track projects to augment supplies, the Indian industry needs to improve its competitiveness. The Indian market is growing and multinationals with newer technologies are now more active. The industry, as a consequence, needs strategic alliances and tie-ups with technology suppliers to upgrade their supplies. Thus, due to demand it is a good project for entrepreneurs to invest.
