Question

construction of transformer​

Answer 1

Generally, the name associated with the construction of a transformer is dependant upon how the primary and secondary windings are wound around the central laminated steel core. ... In the “closed-core” type (core form) transformer, the primary and secondary windings are wound outside and surround the core ring.

Answer 2

answer in detail with explanation given below

transformer construction

there are generally two types of transformer

1. core type transformer
2. shell type transformer

These two transformer are differ from each other by the manner in which the winding are wound around the magnetic core.

core type transformer:->

transformer generally contain two winding( primary and secondary winding) .

• in core type transformer winding are in two side of core of transformer .
• The shape are made up of I or T shape .
• it consume more energy then shell type transformer.
• it is less efficient then she'll type transformer.
• it is used in large devices .
• It require less coolant.

Shell type transformer

• In shell type transformer the winding are in between the core of transformer ( that is sandwich like structure )
• it is E ,T and i like shape .
• it consume less energy .
• Efficiency is more .
• required coolant .
• used in small devices generally .
