Statistical Analysis of Impulsive Flashover Voltages Across Solid-Air Interfaces [PDF]
2020 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2020 Within the pulsed power industry, a key factor determining the achievable output voltage of a HV system is the flashover voltage of the insulating parts. Statistical analysis of the breakdown voltages associated with solid-gas interfaces can reveal useful information to aid system designers in the selection of solid materials.
