Electronic mechanism of propagation of nanosecond breakdown channel in liquid organic dielectrics

The mechanism of anode-initiated breakdown in liquid organic dielectrics with long molecular chains is proposed on the basis experimental data high velocities channel propagation organosilicon and organofluorine liquids (~10 7 cm/s), which are comparable to that obtained earlier crystals same conditions. satisfactory explained within model cascade Auger transitions, developed for crystalline materials. According this model, velocity proportional electrical field strength. time delay formation relative voltage pulse rise does not exceed ~5·10 -10 s margin error Keywords: liquid, nanosecond breakdown, mechanism.
