Fmj. Mccluskey et A. Denat, BUBBLE FORMATION IN SYNTHETIC INSULATING LIQUIDS IN A PULSED DIVERGENT ELECTRIC-FIELD, IEEE transactions on dielectrics and electrical insulation, 1(4), 1994, pp. 672-679
This is a study of high field conduction phenomena in two aromatic ins
ulating liquids (monobenzyltoluene and dibenzyltoluene) in a point-pla
ne electrode geometry. These liquids behave qualitatively like saturat
ed hydrocarbons; current instability (electron avalanche) for high eno
ugh fields near the negative point giving rise to a current pulse regi
me, which causes the formation of bubbles by local heating. The genera
tion and dynamics of these bubbles as a function of various parameters
(injected energy, hydrostatic pressure and the nature of the liquid)
are presented and discussed.
