if we consider the construction of transformer there are two
type......as stated over.......shell type and core type. But
if we see it by its use...there are three types of
transformers....1)current transformers....2)Potential
transformers....3)Power transformers.....and if we see it by
its working principle, then there are two type of
transformers...1)step up....2)step down....there is another
type of transformer .....auto transformer
