HV Conduction and Breakdown in Perfluorothreeethylamine at DC Stresses

摘要

In HV experiments with perfluorothreeethylamine one was obtained:rn1. The conductivity was increased 100 times approximately with the electric field up to 250 kV/cm and it wasn't exceed 10~(-14) Ohm~(-1) cm~(-1).rn2. The electric field kept its homogeneity.rn3. The breakdown strength depended on history. In case of power breakdown (electrode area S≈0.5 cm~2) with energy release W≈20-50 J/cm~3 E ≈ 300-350 kV/cm if electrode materials are steel and E ≈s 170-200 kV/cm if electrode material is aluminum. In case of non-power breakdowns E didn't depend on. electrode material nature E ≈ 450-550 kV/cm.
