Multi-pulse nanosecond electrical breakdown in perfluorinated liquids at 140 kV

Abstract

In this work, we present the results of measurements of the electrical breakdown velocity in perfluorinated liquids of several chemical classes. Breakdown is initiated from point anode by 8-ns pulses with a rise time less than 0.5 ns at voltage of 140 kV. We show that perfluorinated esters have close values of breakdown velocity over a wide range of gaps, and demonstrate relatively low jitter in gaps for which time to breakdown is comparable to pulse duration.
