Malcolm,
I have experienced it also. I think it is a charge stored in the secondary
plastic form or the coating over the wire. My capacitor is connected in
series with the primary (spark gaps across the HV mains) so the capacitor
should be shorted when the system is turned off, through the HV transformer
secondary and the low resistance primary.
