    The transformer I have has a secondary resistance of about 
17,000 ohms and is rated at 4.5 kV and 7.5 VA (I think - I'd have to 
dig it out and look) so the short-circuit current could be  as much 
as a quarter of an amp.  I agree that the operating current would be 
minute in a copier application.
    What's the resistance of your unit and do you know why these 
things have two insulated terminals?
