    Galvanic Isolation is all about preventing the 'current flow' within the circuit or assembly. But note that energy will still flow within the system through other means - capacitance, inductance, optic or other means. The best example of galvanic isolation is your regular transformer - note that the primary and secondary windings aren't 'connected' to permit current flow, but they still form a part of the connected system. Is that what you want to know? It'd help if you could ask specific questions about the parts that you found difficult to understand.

    why galvanic isolation is done? does it make use of 1:1 turns ratio transformer?

    Transformer action is not related here friend. Galvanic Isolation is used to prevent a material contact made up of two or more metals from corroding due to environmental effects.

    This isolation prevents the setting up of Galvanic cells based on the EMF series being formed.

    Again adding to whats said above, it's the property of magnetism and mutual inductance that makes it happen.
