I mean to say by simply having a common ground for both primary and secondary can i avoid isolation property of transformer?

If you want to have no isolation, then use a autotransformer. BTW, why do you want to avoid 'isolation'?

You will still have the energy isolation of the transformer. This is useful for breaking up a ground-loop or defining a new neutral/ground point for the secondary power circuit.

@anyone,

OP did not say why he wants to avoid isolation. If he wants no isolation, he can use a autotransformer.
