    Hi! What will be happen if in the below circuit null and one of phases of three phase are replaced, that is, if we have two phases in the primary of transformer?!!

    Are you thinking that the transformer will work on Two phases, it wont, it will burn out and blow up.

    I suspect he means replacing the "null" neutral and phase with with two phase across transformer primary?
    In that case it usually means you will have about double the volts on the primary, double the volts out of the secondary, you most likely blow the fuse and possibly destroy the VDR and maybe the filter caps (depends on their volt rating). Probably won't do the transformer any good either.
    Why would anyone want to do that anyway????
