All,
I am in the process of constructing a plate cap and need to know
the
breakdown voltage of polypropylene. I know that as the thickness
decreases the
breakdown voltages increases but have no way of getting a good estimate
for how
much of a safety margin I should build into my caps. I'd like to
over-engineer these
babies a little bit but on the other hand don't want to waste a ton of
money.
I plan on using two layers of 2.4 mil poly between each layer of
foil and building a number of sections that will will connected in
series to obtain the proper voltage rating.
Any help would be appreciated.
