Answer / t. arun kumar

Basically classified based on useage requirements,
* step up
* step down
further based on phase as,
* 1 phase
* 3 phase
one more important type is,
## auto transformer

Answer / kavitha

types of transformer depends on different factors
ie its contruction,type of cooling, no of turns etc.....

construction:
shell type
core type

type of cooling:
oil filled
oil filled air cooled
oil filled air blast type

NO OF TURNS:
step down transformer
step transformer

Answer / praveen

main types are 1)step down and step up transformers
2)single phase and three phase transformers
again subdivided in core type and shell type....

one more catagory is
1)distribution and power transformers
2)instrument transformer
a)current transformer
b)potential transformer
3)constant voltage transformer
4)constant voltage transformer
5)tap changing transformer

Answer / kiranmai
