Effect of temperature on the dielectric properties of hydrofluoroethers and fluorinated ketone
Abstract
<p>The AC and DC dielectric properties of hydrofluoroethers (HFE) [C<sub>3</sub>F<sub>7 </sub>OCH<sub>3</sub>] and fluorinated ketone (FK) [C<sub>2</sub>F<sub>5</sub>C(O)CF(CF<sub>3</sub>)<sub>2</sub>] have been characterised by dielectric spectroscopy and DC conductivity at different temperatures. Results show that DC conductivity and imaginary permittivity of both fluids are positively correlated with increasing temperature. However, the real permittivity decreases with increasing temperature. The breakdown voltages of HFE and FK at 295 K are∼10 kV mm<sup>−1</sup>. Reducing temperature is an effective method to increase the breakdown voltage of the FK coolant, but the breakdown voltage of HFE is less temperature dependent. Finally, as expected repeated breakdown had no significant effect on the AC dielectric strength of both liquids.</p>
