About Transformers

Transformers are one of our main products and it is considered as the most important electrical machinery. We are offering step-up and step-down power and distribution transformers, amongst the other products. These are used for converting the low voltage to high voltage or vice versa. The principle of working of transformers is electro-magnetic induction. This is possible only in static devices that too if the magnetic flux varies continuously.

There is a single core on which the primary as well as secondary windings are wound. Also for both windings, the magnetic flux remains same. This flux is dependent on the on the magnetized current in the primary winding along with the number of turns present in it. Consequently, the value of induced voltage is same as that the primary & secondary winding. Adding on, the number of turns in respective windings is proportional to the absolute value of induced voltage.

Parts of a Transformer

There are nine basic parts or components of a transformer that are core, windings, insulating material, transformer oil, tap changer, oil conservator, breather, buchholz relay and explosion vent. more
