3 Phase Transformers and Their Role in Power Distribution

One may be forced to think that 3 phase transformer is indispensable and are extremely important in stepping up and down of voltage. This is in fact partially true, no one can deny the importance of 3 phase transformer in this regards but in reality the same work can be done with the help of a group of single phase transformers as well. In reality regular single phase transformers can be merged together to transform power between two 3 phase transformer in numerous variety of configurations. But everyone and everything has its place of importance. 

The lesser amount of material required to construct a 3 phase transformer and their greater efficiency make them the perfect suited transformer for undertaking these power distribution work. This is a fact that they are of small size & weigh less than their modular counterparts and because they are more in demand.

A three phase transformer is made basically from three sets of primary and secondary windings. One leg of iron core assembly is wound by each set of windings. The structure looks more or less 3 single phase transformers which are sharing a single joined core. The power transformed and stepped down from the main power station is send for domestic and industrial purpose via the thick cabled wires. The fact that 20KV of high voltage is quickly turned into 220V of power is an astonishing achievement in itself and 3 phase transformer is perfected to do this speaks volume of its importance.
