“…Despite its long history, the theory of the electric breakdown of a gas-the abrupt transition of the insulating state into an electrically conducting plasma when a certain voltage threshold between the electrodes is exceeded-remained a subject of intense study throughout the 20th century up to the present time. Besides scientific curiosity, the sustained interest in the phenomenon is certainly also driven by its high practical relevance in numerous areas of technology, ranging from the design of particle detectors [3] to the dimensioning of new nanosecond pulsed ignition systems for internal combustion engines [4], to the determination of appropriate clearance distances in high voltage apparatus [5].…”

This paper provides a theoretical and conceptual framework for the determination of static breakdown inception thresholds in quasi-uniform gas gaps bounded by dielectric layers of thickness s and relative permittivity eps'. The special case of uncoated metallic electrodes is included in the limit s/eps' -> 0. Moreover, a review of breakdown mechanisms and the underlying physical processes in quasi-uniform gas gaps is provided, and the applicability of the associated breakdown criteria is discussed. The results include a parametrization of the partial discharge inception voltage of wedge-shaped air gaps at atmospheric pressure as a function of the reduced coating thickness s/eps'. The predicted results for this prototypical insulation geometry agree well with a broad array of literature data and own measurements. Finally, a physically motivated parametrization of the ionization threshold K(d) is suggested for atmospheric pressure air in terms of secondary electron feedback by energetic photons and ion-enhanced field emission. This contrasts with the ad hoc introduction of modified "streamer constants'' often found in literature to explain breakdown voltages that deviate from the predictions of the classical Raether-Meek-Loeb criterion.
