I have worked for years using a breakdown potential for air (dry?) of
15KV/cm to estimate the potential of my VDGs. and I certainly cannot recall
my source for this figure . Karl has quoted a value of 8KV/cm which is

Can someone supply a confirmation of either/neither figure or source where a
reasonable value for the voltage can be obtained ? Ta.
