Construction of single-phase transformers- A single-phase transformer consists of two winding, called primary and secondary windings mounted on a magnetic core. To confine flux to a definite path magnetic flux is used. Transformer cores are made from thin sheets (called lamination) of high-grade silicon steel. The laminations reduce eddy-current loss Read more…
Oil conservator It is a drum shaped cylindrical vessel mounted on the top of the transformer. it is connected to a pipe to the transformer tank containing oil. the oil expands and contracts to depend upon the heat produced and the oil level in the conservator rises and fails. so, Read more…
Drying of oil- If the dielectric strength of oil is low, then the oil is treated in a filtering plant and drying plant will increase its dielectric strength. The oil should be drawn from near the bottom and deliver back into the transformer tank at the top. This process is Read more…
The following factors are taken into consideration at the time of installing transformers. Proper foundation- The foundation must be strong enough to bear the load of transformer without any vibration and must be made with proper floor label and plinth label. The label of concrete plinth should be above the Read more…
