    Hi all,

    Good morning. As we all know that the transformer provides isolation and Just I need to know which part of a transformer provide isolation( core or some thing else)

    Regards,
    Saravanan.K

    It provides isolation because the primary and secondary windings are not electrically connected physically, only induced voltages by the magnetic effect.

    Insulation between primary conductor and secondary conductor.

    Take a conventional transformer: it is made by winding one set of turns (the "primary") around a core material, then adding a seccond set of turns (the "secondary").

    Since these wires are unconnected there is isolation.

    Power is transmitted via the magnetic field the primary induces in the core. This field is also seen by the seccondary, so the output is powered by the input, just not directly as with electrons or any direct current path between the sides.

    AKA Galvanic Isolation.
