    I am Designing the Linear power supply using Three CTs arranged in the STAR-DELTA form.
    Each CTs are 10A/1.5A Rated.
    I have struggled to calculate the voltage in the Delta windings.
    Pls any one HELP.......

    Please provide additional information, as your post makes very little sense as is.

    By "CT" do you mean "current transformer?" What do you mean by "star-delta" configuration? (Perhaps "star or delta?) What does this have to do with a linear regulator?

    Can you provide a schematic?

    Isn't that confusing? IIRC we use CT for measurement purpose only. A supply using CT is somewhat unorthodox. Using CT's as CT It might be hard to determine the voltage anyways. Of course I'm thinking from a theoretical point, also, the dangers of using CT but perhaps I'm not thinking in the right direction.

    By star-delta perhaps the OP means: primary;wye & secondary;delta?
