    Is it good idea to put shield (thin layer of copper) between primary and secondary windings to decrease capacitance effects?

    hi sil,
    It is often added to Isolation transformers, it should be grounded.
    NOTE: Do not make it a closed conductive path, as it will be seen as a 'shorted turn'...:eek:
    Use insulating tape to ensure that the ends/body of shield do not touch.
