Capacitor charge/ discharge
My understanding of a hv discharge cap (oil filled type) was that it's
construction was essentially the same as a normal oil filled capacitor
except for much heavier multiple connections to the internal structure
and possibly a non rolled construction so as to withstand higher
currents and minimize parasitic inductance. What is the mechanism by
which these caps will not tolerate low current charging? Is the internal
construction different to what I have described?
