In this article, uniform field electric strength measurements on a range of fluorocarbon vapours were reported, over a temperature range of −40°C to temperatures just below the respective boiling points and for gap spacings in the range 1.5-5 mm.Abstract:
Uniform-field electric-strength measurements on a range of fluorocarbon vapours are reported. The fully fluorinated compounds were examined over a temperature range of −40°C to temperatures just below the respective boiling points and for gap spacings in the range 1.5–5 mm. The electric strengths and breakdown distributions are interpreted in terms of the ionisation and attachment processes taking place. The utilisation of the exceptionally good dielectric properties of these materials when operated as evaporative coolants/insulants is discussed.read more

A comparison of the electrical breakdown characteristics of hydro- and fluorocarbon liquids
TL;DR: In this paper, the substitution of fluorine is seen to enhance the electric strength under uniform field conditions, although it produces and increase only for low molecular weight materials in divergent fields.

Breakdown Probability of a Low Pressure Gas Discharge
TL;DR: In this paper, the probability distribution of the number of electrons in an "avalanche" in a low pressure gas discharge is calculated and the result applied to the calculation of the breakdown probability.

TL;DR: In this paper, a study of the steady-state current in electron-attaching gases suggests that this equation is nearly that for which the ionization and attachment coefficients are equal.

Electric Strength of Saturated Hydrocarbon Gases

TL;DR: In this article, an attempt has been made to correlate the sparking potentials of nonattaching polyatomic gases with molecular structure, using a Townsend-like criterion for breakdown, with certain assumptions, to calculate from the measurements relative cross sections for electron scattering by these molecules.
