Hi Rich and all others:
Thanks a lot for clarifying this issue. I was living with one wrong idea about
electro-static build-up mechanisms until you guys got me the right explanation.
This to me is another confirmation of the value of this forum.
Thank you again,
Paolo

Hi Paolo:
>From the other responses to your question, it appears
that there are several phenomena that apply.
Upon reading the other responses, and reading the
referenced web sites, it appears that, in a humid
atmosphere, build-up of electrostatic charge is
limited by micro-condensation on material surfaces,
which tend to bleed off charge before it can build
to a value sufficient to break down the electric
strength of the air.
So, there appears to be no conflict between the fact
that humid air has a slightly higher dielectric
strength than dry air, and the fact that humid air
limits the build-up of surface charge compared to
dry air.
(I have not copied the list with this response, but
I did want to reply to you personally since you had
ask a question of me personally.)
Best regards,
Rich
