Dielectric Strength of Liquids for Short Pulses of Voltage

Abstract

EXPERIMENTS in progress here show a systematic increase in the dielectric strength of pure organic liquids as the duration of the pulse of voltage is decreased. In other words, between the instant of applying a field and the instant of breakdown there is a time-delay which becomes less as the field-strength is raised above the normal breakdown value. A suggestion of this delay can be seen in the early oscillograms of Rogowski, Flegler and Tamm¹.
