The thesis constitutes a systematic theoretical and experimental investigation into impulse breakdown voltage-time curves of coaxial-cylinder gaps in SF(,6) and a 50% SF(,6) - 50% N(,2) mixture. The breakdown time delay probability is treated as a bivariate distribution in statistical and formative time lags. A method is developed to deduce the marginal breakdown voltage probability curve from statistics of time delay. The experimental work was performed on 2.54/7.0-cm diameter, 60-cm long coaxial-cylinder electrodes using SF(,6) or SF(,6)-N(,2) mixtures at pressures of 0.1 - 0.3 MPa subjected to 0.5/50-(mu)s and 1.2/50-(mu)s impulses of both polarities. The effect of a spherical conducting particle attached to the central electrode of the coaxial-cylinder gap on the voltage-time characteristics is also investigated.
